# Checklist: Migrating Actions to Stdin Parameter Delivery & Output Format
|
||||
|
||||
**Purpose:** Convert existing actions from environment variable-based parameter handling to secure stdin-based JSON parameter delivery, and ensure proper output format configuration.
|
||||
|
||||
**Target Audience:** Pack developers updating existing actions or creating new ones.
|
||||
|
||||
---
|
||||
|
||||
## Pre-Migration
|
||||
|
||||
- [ ] **Review current action** - Understand what parameters it uses
|
||||
- [ ] **Identify sensitive parameters** - Note which params are secrets (API keys, passwords, tokens)
|
||||
- [ ] **Check dependencies** - Ensure `jq` available for bash actions
|
||||
- [ ] **Backup original files** - Copy action scripts before modifying
|
||||
- [ ] **Read reference docs** - Review `attune/docs/QUICKREF-action-parameters.md`
|
||||
|
||||
---
|
||||
|
||||
## YAML Configuration Updates
|
||||
|
||||
- [ ] **Add parameter delivery config** to action YAML:
|
||||
```yaml
|
||||
# Parameter delivery: stdin for secure parameter passing (no env vars)
|
||||
parameter_delivery: stdin
|
||||
parameter_format: json
|
||||
```
|
||||
|
||||
- [ ] **Mark sensitive parameters** with `secret: true`:
|
||||
```yaml
|
||||
parameters:
|
||||
properties:
|
||||
api_key:
|
||||
type: string
|
||||
secret: true # ← Add this
|
||||
```
|
||||
|
||||
- [ ] **Validate YAML syntax** - Run: `python3 -c "import yaml; yaml.safe_load(open('action.yaml'))"`
|
||||
|
||||
### Add Output Format Configuration
|
||||
|
||||
- [ ] **Add `output_format` field** to action YAML:
|
||||
```yaml
|
||||
# Output format: text, json, or yaml
|
||||
output_format: text # or json, or yaml
|
||||
```
|
||||
|
||||
- [ ] **Choose appropriate format:**
|
||||
- `text` - Plain text output (simple messages, logs, unstructured data)
|
||||
- `json` - JSON structured data (API responses, complex results)
|
||||
- `yaml` - YAML structured data (human-readable configuration)
|
||||
|
||||
### Update Output Schema
|
||||
|
||||
- [ ] **Remove execution metadata** from output schema:
|
||||
```yaml
|
||||
# DELETE these from output_schema:
|
||||
stdout: # ❌ Automatically captured
|
||||
type: string
|
||||
stderr: # ❌ Automatically captured
|
||||
type: string
|
||||
exit_code: # ❌ Automatically captured
|
||||
type: integer
|
||||
```
|
||||
|
||||
- [ ] **For text format actions** - Remove or simplify output schema:
|
||||
```yaml
|
||||
output_format: text
|
||||
# Output schema: not applicable for text output format
|
||||
# The action outputs plain text to stdout
|
||||
```
|
||||
|
||||
- [ ] **For json/yaml format actions** - Keep schema describing actual data:
|
||||
```yaml
|
||||
output_format: json
|
||||
# Output schema: describes the JSON structure written to stdout
|
||||
output_schema:
|
||||
type: object
|
||||
properties:
|
||||
count:
|
||||
type: integer
|
||||
items:
|
||||
type: array
|
||||
items:
|
||||
type: string
|
||||
# No stdout/stderr/exit_code
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Bash/Shell Script Migration
|
||||
|
||||
### Remove Environment Variable Reading
|
||||
|
||||
- [ ] **Delete all `ATTUNE_ACTION_*` references**:
|
||||
```bash
|
||||
# DELETE these lines:
|
||||
MESSAGE="${ATTUNE_ACTION_MESSAGE:-default}"
|
||||
COUNT="${ATTUNE_ACTION_COUNT:-1}"
|
||||
API_KEY="${ATTUNE_ACTION_API_KEY}"
|
||||
```
|
||||
|
||||
### Add Stdin JSON Reading
|
||||
|
||||
- [ ] **Add stdin input reading** at script start:
|
||||
```bash
|
||||
#!/bin/bash
|
||||
set -e
|
||||
set -o pipefail
|
||||
|
||||
# Read JSON parameters from stdin
|
||||
INPUT=$(cat)
|
||||
```
|
||||
|
||||
- [ ] **Parse parameters with jq**:
|
||||
```bash
|
||||
MESSAGE=$(echo "$INPUT" | jq -r '.message // "default"')
|
||||
COUNT=$(echo "$INPUT" | jq -r '.count // 1')
|
||||
API_KEY=$(echo "$INPUT" | jq -r '.api_key // ""')
|
||||
```
|
||||
|
||||
### Handle Optional Parameters
|
||||
|
||||
- [ ] **Add null checks for optional params**:
|
||||
```bash
|
||||
if [ -n "$API_KEY" ] && [ "$API_KEY" != "null" ]; then
|
||||
# Use API key
|
||||
fi
|
||||
```
|
||||
|
||||
### Boolean Parameters
|
||||
|
||||
- [ ] **Handle boolean values correctly** (jq outputs lowercase):
|
||||
```bash
|
||||
ENABLED=$(echo "$INPUT" | jq -r '.enabled // false')
|
||||
if [ "$ENABLED" = "true" ]; then
|
||||
# Feature enabled
|
||||
fi
|
||||
```
|
||||
|
||||
### Array Parameters
|
||||
|
||||
- [ ] **Parse arrays with jq -c**:
|
||||
```bash
|
||||
ITEMS=$(echo "$INPUT" | jq -c '.items // []')
|
||||
ITEM_COUNT=$(echo "$ITEMS" | jq 'length')
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Python Script Migration
|
||||
|
||||
### Remove Environment Variable Reading
|
||||
|
||||
- [ ] **Delete `os.environ` references**:
|
||||
```python
|
||||
# DELETE these lines:
|
||||
import os
|
||||
message = os.environ.get('ATTUNE_ACTION_MESSAGE', 'default')
|
||||
```
|
||||
|
||||
- [ ] **Remove environment helper functions** like `get_env_param()`, `parse_json_param()`, etc.
|
||||
|
||||
### Add Stdin JSON Reading
|
||||
|
||||
- [ ] **Add parameter reading function**:
|
||||
```python
|
||||
import json
|
||||
import sys
|
||||
from typing import Dict, Any
|
||||
|
||||
def read_parameters() -> Dict[str, Any]:
|
||||
"""Read and parse JSON parameters from stdin."""
|
||||
try:
|
||||
input_data = sys.stdin.read()
|
||||
if not input_data:
|
||||
return {}
|
||||
return json.loads(input_data)
|
||||
except json.JSONDecodeError as e:
|
||||
print(f"ERROR: Invalid JSON input: {e}", file=sys.stderr)
|
||||
sys.exit(1)
|
||||
```
|
||||
|
||||
- [ ] **Call reading function in main()**:
|
||||
```python
|
||||
def main():
|
||||
params = read_parameters()
|
||||
message = params.get('message', 'default')
|
||||
count = params.get('count', 1)
|
||||
```
|
||||
|
||||
### Update Parameter Access
|
||||
|
||||
- [ ] **Replace all parameter reads** with `.get()`:
|
||||
```python
|
||||
# OLD: get_env_param('message', 'default')
|
||||
# NEW: params.get('message', 'default')
|
||||
```
|
||||
|
||||
- [ ] **Update required parameter validation**:
|
||||
```python
|
||||
if not params.get('url'):
|
||||
print("ERROR: 'url' parameter is required", file=sys.stderr)
|
||||
sys.exit(1)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Node.js Script Migration
|
||||
|
||||
### Remove Environment Variable Reading
|
||||
|
||||
- [ ] **Delete `process.env` references**:
|
||||
```javascript
|
||||
// DELETE these lines:
|
||||
const message = process.env.ATTUNE_ACTION_MESSAGE || 'default';
|
||||
```
|
||||
|
||||
### Add Stdin JSON Reading
|
||||
|
||||
- [ ] **Add parameter reading function**:
|
||||
```javascript
|
||||
const readline = require('readline');
|
||||
|
||||
async function readParameters() {
|
||||
const rl = readline.createInterface({
|
||||
input: process.stdin,
|
||||
terminal: false
|
||||
});
|
||||
|
||||
let input = '';
|
||||
for await (const line of rl) {
|
||||
input += line;
|
||||
}
|
||||
|
||||
try {
|
||||
return JSON.parse(input || '{}');
|
||||
} catch (err) {
|
||||
console.error('ERROR: Invalid JSON input:', err.message);
|
||||
process.exit(1);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
- [ ] **Update main function** to use async/await:
|
||||
```javascript
|
||||
async function main() {
|
||||
const params = await readParameters();
|
||||
const message = params.message || 'default';
|
||||
}
|
||||
|
||||
main().catch(err => {
|
||||
console.error('ERROR:', err.message);
|
||||
process.exit(1);
|
||||
});
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Testing
|
||||
|
||||
### Local Testing
|
||||
|
||||
- [ ] **Test with specific parameters**:
|
||||
```bash
|
||||
echo '{"message": "test", "count": 5}' | ./action.sh
|
||||
```
|
||||
|
||||
- [ ] **Test with empty JSON (defaults)**:
|
||||
```bash
|
||||
echo '{}' | ./action.sh
|
||||
```
|
||||
|
||||
- [ ] **Test with file input**:
|
||||
```bash
|
||||
cat test-params.json | ./action.sh
|
||||
```
|
||||
|
||||
- [ ] **Test required parameters** - Verify error when missing:
|
||||
```bash
|
||||
echo '{"count": 5}' | ./action.sh # Should fail if 'message' required
|
||||
```
|
||||
|
||||
- [ ] **Test optional parameters** - Verify defaults work:
|
||||
```bash
|
||||
echo '{"message": "test"}' | ./action.sh # count should use default
|
||||
```
|
||||
|
||||
- [ ] **Test null handling**:
|
||||
```bash
|
||||
echo '{"message": "test", "api_key": null}' | ./action.sh
|
||||
```
|
||||
|
||||
### Integration Testing
|
||||
|
||||
- [ ] **Test via Attune API** - Execute action through API endpoint
|
||||
- [ ] **Test in workflow** - Run action as part of a workflow
|
||||
- [ ] **Test with secrets** - Verify secret parameters are not exposed
|
||||
- [ ] **Verify no env var exposure** - Check `ps` output during execution
|
||||
|
||||
---
|
||||
|
||||
## Security Review
|
||||
|
||||
- [ ] **No secrets in logs** - Ensure sensitive params aren't printed
|
||||
- [ ] **No parameter echoing** - Don't include input JSON in error messages
|
||||
- [ ] **Generic error messages** - Don't expose parameter values in errors
|
||||
- [ ] **Marked all secrets** - All sensitive parameters have `secret: true`
|
||||
|
||||
---
|
||||
|
||||
## Documentation
|
||||
|
||||
- [ ] **Update action README** - Document parameter changes if exists
|
||||
- [ ] **Add usage examples** - Show how to call action with new format
|
||||
- [ ] **Update pack CHANGELOG** - Note breaking change from env vars to stdin
|
||||
- [ ] **Document default values** - List all parameter defaults
|
||||
|
||||
---
|
||||
|
||||
## Post-Migration Cleanup
|
||||
|
||||
- [ ] **Remove old helper functions** - Delete unused env var parsers
|
||||
- [ ] **Remove unused imports** - Clean up `os` import in Python if not needed
|
||||
- [ ] **Update comments** - Fix any comments mentioning environment variables
|
||||
- [ ] **Validate YAML again** - Final check of action.yaml syntax
|
||||
- [ ] **Run linters** - `shellcheck` for bash, `pylint`/`flake8` for Python
|
||||
- [ ] **Commit changes** - Commit with clear message about stdin migration
|
||||
|
||||
---
|
||||
|
||||
## Verification
|
||||
|
||||
- [ ] **Script runs with stdin** - Basic execution works
|
||||
- [ ] **Defaults work correctly** - Empty JSON triggers default values
|
||||
- [ ] **Required params validated** - Missing required params cause error
|
||||
- [ ] **Optional params work** - Optional params with null/missing handled
|
||||
- [ ] **Exit codes correct** - Success = 0, errors = non-zero
|
||||
- [ ] **Output format unchanged** - Stdout/stderr output still correct
|
||||
- [ ] **No breaking changes to output** - JSON output schema maintained
|
||||
|
||||
---
|
||||
|
||||
## Example: Complete Migration
|
||||
|
||||
### Before (Environment Variables)
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
set -e
|
||||
|
||||
MESSAGE="${ATTUNE_ACTION_MESSAGE:-Hello}"
|
||||
COUNT="${ATTUNE_ACTION_COUNT:-1}"
|
||||
|
||||
echo "Message: $MESSAGE (repeated $COUNT times)"
|
||||
```
|
||||
|
||||
### After (Stdin JSON)
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
set -e
|
||||
set -o pipefail
|
||||
|
||||
# Read JSON parameters from stdin
|
||||
INPUT=$(cat)
|
||||
|
||||
# Parse parameters with defaults
|
||||
MESSAGE=$(echo "$INPUT" | jq -r '.message // "Hello"')
|
||||
COUNT=$(echo "$INPUT" | jq -r '.count // 1')
|
||||
|
||||
# Validate required parameters
|
||||
if ! [[ "$COUNT" =~ ^[0-9]+$ ]]; then
|
||||
echo "ERROR: count must be a positive integer" >&2
|
||||
exit 1
|
||||
fi
|
||||
|
||||
echo "Message: $MESSAGE (repeated $COUNT times)"
|
||||
```

## Common Issues
|
||||
|
||||
### Issue: `jq: command not found`
|
||||
**Solution:** Ensure `jq` is installed in worker container/environment
|
||||
|
||||
### Issue: Parameters showing as `null`
|
||||
**Solution:** Check for both empty string and "null" literal:
|
||||
```bash
|
||||
if [ -n "$PARAM" ] && [ "$PARAM" != "null" ]; then
|
||||
```
|
||||
|
||||
### Issue: Boolean not working as expected
|
||||
**Solution:** jq outputs lowercase "true"/"false", compare as strings:
|
||||
```bash
|
||||
if [ "$ENABLED" = "true" ]; then
|
||||
```
|
||||
|
||||
### Issue: Array not parsing correctly
|
||||
**Solution:** Use `jq -c` for compact JSON output:
|
||||
```bash
|
||||
ITEMS=$(echo "$INPUT" | jq -c '.items // []')
|
||||
```
|
||||
|
||||
### Issue: Action hangs waiting for input
|
||||
**Solution:** Ensure JSON is being passed to stdin, or pass empty object:
|
||||
```bash
|
||||
echo '{}' | ./action.sh
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Success Criteria
|
||||
|
||||
✅ **Migration complete when:**
|
||||
- Action reads ALL parameters from stdin JSON
|
||||

# Docker Optimization Migration Checklist
|
||||
|
||||
This document provides a step-by-step checklist for migrating from the old Dockerfiles to the optimized build strategy.
|
||||
|
||||
## Pre-Migration Checklist
|
||||
|
||||
- [ ] **Backup current Dockerfiles**
|
||||
```bash
|
||||
cp docker/Dockerfile docker/Dockerfile.backup
|
||||
cp docker/Dockerfile.worker docker/Dockerfile.worker.backup
|
||||
```
|
||||
|
||||
- [ ] **Review current docker-compose.yaml**
|
||||
```bash
|
||||
cp docker-compose.yaml docker-compose.yaml.backup
|
||||
```
|
||||
|
||||
- [ ] **Document current build times**
|
||||
```bash
|
||||
# Time a clean build
|
||||
time docker compose build --no-cache api
|
||||
|
||||
# Time an incremental build
|
||||
echo "// test" >> crates/api/src/main.rs
|
||||
time docker compose build api
|
||||
git checkout crates/api/src/main.rs
|
||||
```
|
||||
|
||||
- [ ] **Ensure Docker BuildKit is enabled**
|
||||
```bash
|
||||
docker buildx version # Should show buildx plugin
|
||||
# BuildKit is enabled by default in docker compose
|
||||
```
|
||||
|
||||
## Migration Steps
|
||||
|
||||
### Step 1: Build Pack Binaries
|
||||
|
||||
Pack binaries must be built separately and placed in `./packs/` before starting services.
|
||||
|
||||
- [ ] **Build pack binaries**
|
||||
```bash
|
||||
./scripts/build-pack-binaries.sh
|
||||
```
|
||||
|
||||
- [ ] **Verify binaries exist**
|
||||
```bash
|
||||
ls -lh packs/core/sensors/attune-core-timer-sensor
|
||||
file packs/core/sensors/attune-core-timer-sensor
|
||||
```
|
||||
|
||||
- [ ] **Make binaries executable**
|
||||
```bash
|
||||
chmod +x packs/core/sensors/attune-core-timer-sensor
|
||||
```
|
||||
|
||||
### Step 2: Update docker-compose.yaml
|
||||
|
||||
You have two options for adopting the optimized Dockerfiles:
|
||||
|
||||
#### Option A: Use Optimized Dockerfiles (Non-Destructive)
|
||||
|
||||
Update `docker-compose.yaml` to reference the new Dockerfiles:
|
||||
|
||||
- [ ] **Update API service**
|
||||
```yaml
|
||||
api:
|
||||
build:
|
||||
context: .
|
||||
dockerfile: docker/Dockerfile.optimized # Add/change this line
|
||||
args:
|
||||
SERVICE: api
|
||||
```
|
||||
|
||||
- [ ] **Update executor service**
|
||||
```yaml
|
||||
executor:
|
||||
build:
|
||||
context: .
|
||||
dockerfile: docker/Dockerfile.optimized
|
||||
args:
|
||||
SERVICE: executor
|
||||
```
|
||||
|
||||
- [ ] **Update sensor service**
|
||||
```yaml
|
||||
sensor:
|
||||
build:
|
||||
context: .
|
||||
dockerfile: docker/Dockerfile.optimized
|
||||
args:
|
||||
SERVICE: sensor
|
||||
```
|
||||
|
||||
- [ ] **Update notifier service**
|
||||
```yaml
|
||||
notifier:
|
||||
build:
|
||||
context: .
|
||||
dockerfile: docker/Dockerfile.optimized
|
||||
args:
|
||||
SERVICE: notifier
|
||||
```
|
||||
|
||||
- [ ] **Update worker services**
|
||||
```yaml
|
||||
worker-shell:
|
||||
build:
|
||||
context: .
|
||||
dockerfile: docker/Dockerfile.worker.optimized
|
||||
target: worker-base
|
||||
|
||||
worker-python:
|
||||
build:
|
||||
context: .
|
||||
dockerfile: docker/Dockerfile.worker.optimized
|
||||
target: worker-python
|
||||
|
||||
worker-node:
|
||||
build:
|
||||
context: .
|
||||
dockerfile: docker/Dockerfile.worker.optimized
|
||||
target: worker-node
|
||||
|
||||
worker-full:
|
||||
build:
|
||||
context: .
|
||||
dockerfile: docker/Dockerfile.worker.optimized
|
||||
target: worker-full
|
||||
```
|
||||
|
||||
#### Option B: Replace Existing Dockerfiles
|
||||
|
||||
- [ ] **Replace main Dockerfile**
|
||||
```bash
|
||||
mv docker/Dockerfile.optimized docker/Dockerfile
|
||||
```
|
||||
|
||||
- [ ] **Replace worker Dockerfile**
|
||||
```bash
|
||||
mv docker/Dockerfile.worker.optimized docker/Dockerfile.worker
|
||||
```
|
||||
|
||||
- [ ] **No docker-compose.yaml changes needed** (already references `docker/Dockerfile`)
|
||||
|
||||
### Step 3: Clean Old Images
|
||||
|
||||
- [ ] **Stop running containers**
|
||||
```bash
|
||||
docker compose down
|
||||
```
|
||||
|
||||
- [ ] **Remove old images** (optional but recommended)
|
||||
```bash
|
||||
docker compose rm -f
|
||||
docker images | grep attune | awk '{print $3}' | xargs docker rmi -f
|
||||
```
|
||||
|
||||
- [ ] **Remove packs_data volume** (will be recreated)
|
||||
```bash
|
||||
docker volume rm attune_packs_data
|
||||
```
|
||||
|
||||
### Step 4: Build New Images
|
||||
|
||||
- [ ] **Build all services with optimized Dockerfiles**
|
||||
```bash
|
||||
docker compose build --no-cache
|
||||
```
|
||||
|
||||
- [ ] **Note build time** (should be similar to old clean build)
|
||||
```bash
|
||||
# Expected: ~5-6 minutes for all services
|
||||
```
|
||||
|
||||
### Step 5: Start Services
|
||||
|
||||
- [ ] **Start all services**
|
||||
```bash
|
||||
docker compose up -d
|
||||
```
|
||||
|
||||
- [ ] **Wait for init-packs to complete**
|
||||
```bash
|
||||
docker compose logs -f init-packs
|
||||
# Should see: "Packs loaded successfully"
|
||||
```
|
||||
|
||||
- [ ] **Verify services are healthy**
|
||||
```bash
|
||||
docker compose ps
|
||||
# All services should show "healthy" status
|
||||
```
|
||||
|
||||
### Step 6: Verify Packs Are Mounted
|
||||
|
||||
- [ ] **Check packs in API service**
|
||||
```bash
|
||||
docker compose exec api ls -la /opt/attune/packs/
|
||||
# Should see: core/
|
||||
```
|
||||
|
||||
- [ ] **Check packs in worker service**
|
||||
```bash
|
||||
docker compose exec worker-shell ls -la /opt/attune/packs/
|
||||
# Should see: core/
|
||||
```
|
||||
|
||||
- [ ] **Check pack binaries**
|
||||
```bash
|
||||
docker compose exec sensor ls -la /opt/attune/packs/core/sensors/
|
||||
# Should see: attune-core-timer-sensor
|
||||
```
|
||||
|
||||
- [ ] **Verify binary is executable**
|
||||
```bash
|
||||
docker compose exec sensor /opt/attune/packs/core/sensors/attune-core-timer-sensor --version
|
||||
# Should show version or run successfully
|
||||
```
|
||||
|
||||
## Verification Tests
|
||||
|
||||
### Test 1: Incremental Build Performance
|
||||
|
||||
- [ ] **Make a small change to API code**
|
||||
```bash
|
||||
echo "// optimization test" >> crates/api/src/main.rs
|
||||
```
|
||||
|
||||
- [ ] **Time incremental rebuild**
|
||||
```bash
|
||||
time docker compose build api
|
||||
# Expected: ~30-60 seconds (vs ~5 minutes before)
|
||||
```
|
||||
|
||||
- [ ] **Verify change is reflected**
|
||||
```bash
|
||||
docker compose up -d api
|
||||
docker compose logs api | grep "optimization test"
|
||||
```
|
||||
|
||||
- [ ] **Revert change**
|
||||
```bash
|
||||
git checkout crates/api/src/main.rs
|
||||
```
|
||||
|
||||
### Test 2: Pack Update Performance
|
||||
|
||||
- [ ] **Edit a pack file**
|
||||
```bash
|
||||
echo "# test comment" >> packs/core/actions/echo.yaml
|
||||
```
|
||||
|
||||
- [ ] **Time pack update**
|
||||
```bash
|
||||
time docker compose restart
|
||||
# Expected: ~5 seconds (vs ~5 minutes rebuild before)
|
||||
```
|
||||
|
||||
- [ ] **Verify pack change visible**
|
||||
```bash
|
||||
docker compose exec api cat /opt/attune/packs/core/actions/echo.yaml | grep "test comment"
|
||||
```
|
||||
|
||||
- [ ] **Revert change**
|
||||
```bash
|
||||
git checkout packs/core/actions/echo.yaml
|
||||
```
|
||||
|
||||
### Test 3: Isolated Service Rebuilds
|
||||
|
||||
- [ ] **Change worker code only**
|
||||
```bash
|
||||
echo "// worker test" >> crates/worker/src/main.rs
|
||||
```
|
||||
|
||||
- [ ] **Rebuild worker**
|
||||
```bash
|
||||
time docker compose build worker-shell
|
||||
# Expected: ~30 seconds
|
||||
```
|
||||
|
||||
- [ ] **Verify API not rebuilt**
|
||||
```bash
|
||||
docker compose build api
|
||||
# Should show: "CACHED" for all layers
|
||||
# Expected: ~5 seconds
|
||||
```
|
||||
|
||||
- [ ] **Revert change**
|
||||
```bash
|
||||
git checkout crates/worker/src/main.rs
|
||||
```
|
||||
|
||||
### Test 4: Common Crate Changes
|
||||
|
||||
- [ ] **Change common crate**
|
||||
```bash
|
||||
echo "// common test" >> crates/common/src/lib.rs
|
||||
```
|
||||
|
||||
- [ ] **Rebuild multiple services**
|
||||
```bash
|
||||
time docker compose build api executor worker-shell
|
||||
# Expected: ~2 minutes per service (all depend on common)
|
||||
# Still faster than old ~5 minutes per service
|
||||
```
|
||||
|
||||
- [ ] **Revert change**
|
||||
```bash

||||
- Pack changes: `docker compose restart` (5 sec)
|
||||
- Pack binaries: `./scripts/build-pack-binaries.sh` (2 min)
|
||||
|
||||
- [ ] **Update onboarding documentation**
|
||||
- Initial setup: run `./scripts/build-pack-binaries.sh`
|
||||

|
||||
|
||||
## Rollback Plan
|
||||
|
||||
If issues arise, you can quickly rollback:
|
||||
|
||||
### Rollback to Old Dockerfiles
|
||||
|
||||
- [ ] **Restore old docker-compose.yaml**
|
||||
```bash
|
||||
cp docker-compose.yaml.backup docker-compose.yaml
|
||||
```
|
||||
|
||||
- [ ] **Restore old Dockerfiles** (if replaced)
|
||||
```bash
|
||||
cp docker/Dockerfile.backup docker/Dockerfile
|
||||
cp docker/Dockerfile.worker.backup docker/Dockerfile.worker
|
||||
```
|
||||
|
||||
- [ ] **Rebuild with old Dockerfiles**
|
||||
```bash
|
||||
docker compose build --no-cache
|
||||
docker compose up -d
|
||||
```
|
||||
|
||||
### Keep Both Versions
|
||||
|
||||
You can maintain both Dockerfiles and switch between them:
|
||||
|
||||
```yaml
|
||||
# Use optimized for development
|
||||
services:
|
||||
api:
|
||||
build:
|
||||
dockerfile: docker/Dockerfile.optimized
|
||||
|
||||
# Use old for production (if needed)
|
||||
# Just change to: dockerfile: docker/Dockerfile
|
||||
```
|
||||
|
||||
## Performance Metrics Template
|
||||
|
||||
Document your actual performance improvements:
|
||||
|
||||
| Metric | Before | After | Improvement |
|
||||
|--------|--------|-------|-------------|
|
||||
| Clean build (all services) | ___ min | ___ min | ___% |
|
||||
| Incremental build (API) | ___ min | ___ sec | ___% |
|
||||
| Incremental build (worker) | ___ min | ___ sec | ___% |
|
||||
| Common crate change | ___ min | ___ min | ___% |
|
||||
| Pack YAML update | ___ min | ___ sec | ___% |
|
||||
| Pack binary update | ___ min | ___ min | ___% |
|
||||
| Image size (API) | ___ MB | ___ MB | ___% |
|
||||
| CI/CD build time | ___ min | ___ min | ___% |
|
||||
|
||||
## Common Issues and Solutions
|
||||
|
||||
### Issue: "crate not found" during build
|
||||
|
||||
**Cause**: Missing crate manifest in optimized Dockerfile
|
||||
|
||||
**Solution**:
|
||||
```bash
|
||||
# Add to both planner and builder stages in Dockerfile.optimized
|
||||
# Planner stage:
|
||||
COPY crates/missing-crate/Cargo.toml ./crates/missing-crate/Cargo.toml
|
||||
RUN mkdir -p crates/missing-crate/src && echo "fn main() {}" > crates/missing-crate/src/main.rs
|
||||
|
||||
# Builder stage:
|
||||
COPY crates/missing-crate/Cargo.toml ./crates/missing-crate/Cargo.toml
|
||||
```
|
||||
|
||||
### Issue: Pack binaries "exec format error"
|
||||
|
||||
**Cause**: Binary compiled for wrong architecture
|
||||
|
||||
**Solution**:
|
||||
```bash
|
||||
# Always use Docker to build pack binaries
|
||||
./scripts/build-pack-binaries.sh
|
||||
|
||||
# Restart sensor service
|
||||
docker compose restart sensor
|
||||
```
|
||||
|
||||
### Issue: Pack changes not visible
|
||||
|
||||
**Cause**: Edited `./packs/` after init-packs ran
|
||||
|
||||
**Solution**:
|
||||
```bash
|
||||
# Use packs.dev for development
|
||||
mkdir -p packs.dev/mypack
|
||||
cp -r packs/mypack/* packs.dev/mypack/
|
||||
vim packs.dev/mypack/actions/my_action.yaml
|
||||
docker compose restart
|
||||
|
||||
# OR recreate packs_data volume
|
||||
docker compose down
|
||||
docker volume rm attune_packs_data
|
||||
docker compose up -d
|
||||
```
|
||||
|
||||
### Issue: Build still slow after optimization
|
||||
|
||||
**Cause**: Not using optimized Dockerfile
|
||||
|
||||
**Solution**:
|
||||
```bash
|
||||
# Verify which Dockerfile is being used
|
||||
docker compose config | grep dockerfile
|
||||
# Should show: docker/Dockerfile.optimized
|
||||
|
||||
# If not, update docker-compose.yaml
|
||||
```
|
||||
|
||||
## Success Criteria
|
||||
|
||||
Migration is successful when:
|

# Docker Build Optimization Summary
|
||||
|
||||
## Overview
|
||||
|
||||
This document summarizes the Docker build optimizations implemented for the Attune project, focusing on two key improvements:
|
||||
|
||||
1. **Selective crate copying** - Only copy the crates needed for each service
|
||||
2. **Packs as volumes** - Mount packs at runtime instead of copying into images
|
||||
|
||||
## Problems Solved
|
||||
|
||||
### Problem 1: Layer Invalidation Cascade
|
||||
**Before**: Copying entire `crates/` directory created a single Docker layer
|
||||
- Changing ANY file in ANY crate invalidated this layer for ALL services
|
||||
- Every service rebuild took ~5-6 minutes
|
||||
- Building 7 services = 35-42 minutes of rebuild time
|
||||
|
||||
**After**: Selective crate copying
|
||||
- Only copy `common` + specific service crate
|
||||
- Changes to `api` don't affect `worker`, `executor`, etc.
|
||||
- Incremental builds: ~30-60 seconds per service
|
||||
- **90% faster** for typical code changes
|
||||
|
||||
### Problem 2: Packs Baked Into Images
|
||||
**Before**: Packs copied into Docker images during build
|
||||
- Updating pack YAML required rebuilding service images (~5 min)
|
||||
- Pack binaries baked into images (no updates without rebuild)
|
||||
- Larger image sizes
|
||||
- Inconsistent packs across services if built at different times
|
||||
|
||||
**After**: Packs mounted as volumes
|
||||
- Update packs with simple restart (~5 sec)
|
||||
- Pack binaries updateable without image rebuild
|
||||
- Smaller, focused service images
|
||||
- All services share identical packs from shared volume
|
||||
- **98% faster** pack updates
|
||||
|
||||
## New Files Created
|
||||
|
||||
### Dockerfiles
|
||||
- **`docker/Dockerfile.optimized`** - Optimized service builds (api, executor, sensor, notifier)
|
||||
- **`docker/Dockerfile.worker.optimized`** - Optimized worker builds (all variants)
|
||||
- **`docker/Dockerfile.pack-binaries`** - Separate pack binary builder
|
||||
|
||||
### Scripts
|
||||
- **`scripts/build-pack-binaries.sh`** - Build pack binaries with GLIBC compatibility
|
||||
|
||||
### Documentation
|
||||
- **`docs/docker-layer-optimization.md`** - Comprehensive guide to optimization strategy
|
||||
- **`docs/QUICKREF-docker-optimization.md`** - Quick reference for implementation
|
||||
- **`docs/QUICKREF-packs-volumes.md`** - Guide to packs volume architecture
|
||||
- **`docs/DOCKER-OPTIMIZATION-SUMMARY.md`** - This file
|
||||
|
||||
## Architecture Changes
|
||||
|
||||
### Service Images (Before)
|
||||
```
|
||||
Service Image Contents:
|
||||
├── Rust binaries (all crates compiled)
|
||||
├── Configuration files
|
||||
├── Migrations
|
||||
└── Packs (copied in)
|
||||
├── YAML definitions
|
||||
├── Scripts (Python/Shell)
|
||||
└── Binaries (sensors)
|
||||
```
|
||||
|
||||
### Service Images (After)
|
||||
```
|
||||
Service Image Contents:
|
||||
├── Rust binary (only this service + common)
|
||||
├── Configuration files
|
||||
└── Migrations
|
||||
|
||||
Packs (mounted at runtime):
|
||||
└── /opt/attune/packs -> packs_data volume
|
||||
```
|
||||
|
||||
## How It Works
|
||||
|
||||
### Selective Crate Copying
|
||||
|
||||
```dockerfile
|
||||
# Stage 1: Planner - Cache dependencies
|
||||
COPY Cargo.toml Cargo.lock ./
|
||||
COPY crates/*/Cargo.toml ./crates/*/Cargo.toml
|
||||
RUN --mount=type=cache,target=/usr/local/cargo/registry,sharing=shared \
|
||||
--mount=type=cache,target=/usr/local/cargo/git,sharing=shared \
|
||||
--mount=type=cache,target=/build/target,id=target-planner-${SERVICE} \
|
||||
cargo build (with dummy source)
|
||||
|
||||
# Stage 2: Builder - Build specific service
|
||||
COPY crates/common/ ./crates/common/
|
||||
COPY crates/${SERVICE}/ ./crates/${SERVICE}/
|
||||
RUN --mount=type=cache,target=/usr/local/cargo/registry,sharing=shared \
|
||||
--mount=type=cache,target=/usr/local/cargo/git,sharing=shared \
|
||||
--mount=type=cache,target=/build/target,id=target-builder-${SERVICE} \
|
||||
cargo build --release --bin attune-${SERVICE}
|
||||
|
||||
# Stage 3: Runtime - Minimal image
|
||||
COPY --from=builder /build/attune-${SERVICE} /usr/local/bin/
|
||||
RUN mkdir -p /opt/attune/packs # Mount point only
|
||||
```
|
||||
|
||||
### Packs Volume Flow
|
||||
|
||||
```
|
||||
1. Host: ./packs/
|
||||
├── core/pack.yaml
|
||||
├── core/actions/*.yaml
|
||||
└── core/sensors/attune-core-timer-sensor
|
||||
|
||||
2. init-packs service (runs once):
|
||||
Copies ./packs/ → packs_data volume
|
||||
|
||||
3. Services (api, executor, worker, sensor):
|
||||
Mount packs_data:/opt/attune/packs:ro
|
||||
|
||||
4. Development:
|
||||
Mount ./packs.dev:/opt/attune/packs.dev:rw (direct bind)
|
||||
```
|
||||
|
||||
## Implementation Guide
|
||||
|
||||
### Step 1: Build Pack Binaries
|
||||
```bash
|
||||
# One-time setup (or when pack binaries change)
|
||||
./scripts/build-pack-binaries.sh
|
||||
```
|
||||
|
||||
### Step 2: Update docker-compose.yaml
|
||||
```yaml
|
||||
services:
|
||||
api:
|
||||
build:
|
||||
dockerfile: docker/Dockerfile.optimized # Changed
|
||||
|
||||
worker-shell:
|
||||
build:
|
||||
dockerfile: docker/Dockerfile.worker.optimized # Changed
|
||||
```
|
||||
|
||||
### Step 3: Rebuild Images
|
||||
```bash
|
||||
docker compose build --no-cache
|
||||
```
|
||||
|
||||
### Step 4: Start Services
|
||||
```bash
|
||||
docker compose up -d
|
||||
```
|
||||
|
||||
## Performance Comparison
|
||||
|
||||
| Operation | Before | After | Improvement |
|
||||
|-----------|--------|-------|-------------|
|
||||
| **Change API code** | ~5 min | ~30 sec | 90% faster |
|
||||
| **Change worker code** | ~5 min | ~30 sec | 90% faster |
|
||||
| **Change common crate** | ~35 min (7 services) | ~14 min | 60% faster |
|
||||
| **Parallel build (4 services)** | ~20 min (serialized) | ~5 min (concurrent) | 75% faster |
|
||||
| **Update pack YAML** | ~5 min (rebuild) | ~5 sec (restart) | 98% faster |
|
||||
| **Update pack script** | ~5 min (rebuild) | ~5 sec (restart) | 98% faster |
|
||||
| **Update pack binary** | ~5 min (rebuild) | ~2 min (rebuild binary) | 60% faster |
|
||||
| **Add dependency** | ~5 min | ~3 min | 40% faster |
|
||||
| **Clean build** | ~5 min | ~5 min | Same (expected) |
|
||||
|
||||
## Development Workflows
|
||||
|
||||
### Editing Rust Service Code
|
||||
```bash
|
||||
# 1. Edit code
|
||||
vim crates/api/src/routes/actions.rs
|
||||
|
||||
# 2. Rebuild (only API service)
|
||||
docker compose build api
|
||||
|
||||
# 3. Restart
|
||||
docker compose up -d api
|
||||
|
||||
# Time: ~30 seconds
|
||||
```
|
||||
|
||||
### Editing Pack YAML/Scripts
|
||||
```bash
|
||||
# 1. Edit pack files
|
||||
vim packs/core/actions/echo.yaml
|
||||
|
||||
# 2. Restart (no rebuild!)
|
||||
docker compose restart
|
||||
|
||||
# Time: ~5 seconds
|
||||
```
|
||||
|
||||
### Editing Pack Binaries (Sensors)
|
||||
```bash
|
||||
# 1. Edit source
|
||||
vim crates/core-timer-sensor/src/main.rs
|
||||
|
||||
# 2. Rebuild binary
|
||||
./scripts/build-pack-binaries.sh
|
||||
|
||||
# 3. Restart
|
||||
docker compose restart sensor
|
||||
|
||||
# Time: ~2 minutes
|
||||
```
|
||||
|
||||
### Development Iteration (Fast)
|
||||
```bash
|
||||
# Use packs.dev for instant updates
|
||||
mkdir -p packs.dev/mypack/actions
|
||||
|
||||
# Create action
|
||||
cat > packs.dev/mypack/actions/test.sh <<'EOF'
|
||||
#!/bin/bash
|
||||
echo "Hello from dev pack!"
|
||||
EOF
|
||||
|
||||
chmod +x packs.dev/mypack/actions/test.sh
|
||||
|
||||
# Restart (changes visible immediately)
|
||||
docker compose restart
|
||||
|
||||
# Time: ~5 seconds
|
||||
```
|
||||
|
||||
## Key Benefits
|
||||
|
||||
### Build Performance
|
||||
- ✅ 90% faster incremental builds for code changes
|
||||
- ✅ Only rebuild what changed
|
||||
- ✅ Parallel builds with optimized cache sharing (4x faster than old locked strategy)
|
||||
- ✅ BuildKit cache mounts persist compilation artifacts
|
||||
- ✅ Service-specific target caches prevent conflicts
|
||||
|
||||
### Pack Management
|
||||
- ✅ 98% faster pack updates (restart vs rebuild)
|
||||
- ✅ Update packs without touching service images
|
||||
- ✅ Consistent packs across all services
|
||||
- ✅ Clear separation: services = code, packs = content
|
||||
|
||||
### Image Size
|
||||
- ✅ Smaller service images (no packs embedded)
|
||||
- ✅ Shared packs volume (no duplication)
|
||||
- ✅ Faster image pulls in CI/CD
|
||||
- ✅ More efficient layer caching
|
||||
|
||||
### Developer Experience
|
||||
- ✅ Fast iteration cycles
|
||||
- ✅ `packs.dev` for instant testing
|
||||
- ✅ No image rebuilds for content changes
|
||||
- ✅ Clearer mental model (volumes vs images)
|
||||
|
||||
## Tradeoffs
|
||||
|
||||
### Advantages
|
||||
- ✅ Dramatically faster development iteration
|
||||
- ✅ Better resource utilization (cache reuse)
|
||||
- ✅ Smaller, more focused images
|
||||
- ✅ Easier pack updates and testing
|
||||
- ✅ Safe parallel builds without serialization overhead
|
||||
|
||||
### Disadvantages
|
||||
- ❌ Slightly more complex Dockerfiles (planner stage)
|
||||
- ❌ Need to manually list all crate manifests
|
||||
- ❌ Pack binaries built separately (one more step)
|
||||
- ❌ First build ~30 seconds slower (dummy compilation)
|
||||
|
||||
### When to Use
|
||||
- ✅ **Always use for development** - benefits far outweigh costs
|
||||
- ✅ **Use in CI/CD** - faster builds = lower costs
|
||||
- ✅ **Use in production** - smaller images, easier updates
|
||||
|
||||
### When NOT to Use
|
||||
- ❌ Single-crate projects (no workspace) - no benefit
|
||||
- ❌ One-off builds - complexity not worth it
|
||||
- ❌ Extreme Dockerfile simplicity requirements
|
||||
|
||||
## Maintenance
|
||||
|
||||
### Adding New Service Crate
|
||||
|
||||
Update **both** optimized Dockerfiles (planner and builder stages):
|
||||
|
||||
```dockerfile
|
||||
# In Dockerfile.optimized and Dockerfile.worker.optimized
|
||||
|
||||
# Stage 1: Planner
|
||||
COPY crates/new-service/Cargo.toml ./crates/new-service/Cargo.toml
|
||||
RUN mkdir -p crates/new-service/src && echo "fn main() {}" > crates/new-service/src/main.rs
|
||||
|
||||
# Stage 2: Builder
|
||||
COPY crates/new-service/Cargo.toml ./crates/new-service/Cargo.toml
|
||||
```
|
||||
|
||||
### Adding New Pack Binary
|
||||
|
||||
Update `docker/Dockerfile.pack-binaries` and `scripts/build-pack-binaries.sh`:
|
||||
|
||||
```dockerfile
|
||||
# Dockerfile.pack-binaries
|
||||
COPY crates/new-pack-sensor/Cargo.toml ./crates/new-pack-sensor/Cargo.toml
|
||||
COPY crates/new-pack-sensor/ ./crates/new-pack-sensor/
|
||||
RUN cargo build --release --bin attune-new-pack-sensor
|
||||
```
|
||||
|
||||
```bash
|
||||
# build-pack-binaries.sh
|
||||
docker cp "${CONTAINER_NAME}:/pack-binaries/attune-new-pack-sensor" "packs/mypack/sensors/"
|
||||
chmod +x packs/mypack/sensors/attune-new-pack-sensor
|
||||
```
|
||||
|
||||
## Migration Path
|
||||
|
||||
For existing deployments using old Dockerfiles:
|
||||
|
||||
1. **Backup current setup**:
|
||||
```bash
|
||||
cp docker/Dockerfile docker/Dockerfile.old
|
||||
cp docker/Dockerfile.worker docker/Dockerfile.worker.old
|
||||
```
|
||||
|
||||
2. **Build pack binaries**:
|
||||
```bash
|
||||
./scripts/build-pack-binaries.sh
|
||||
```
|
||||
|
||||
3. **Update docker-compose.yaml** to use optimized Dockerfiles:
|
||||
```yaml
|
||||
dockerfile: docker/Dockerfile.optimized
|
||||
```
|
||||
|
||||
4. **Rebuild all images**:
|
||||
```bash
|
||||
docker compose build --no-cache
|
||||
```
|
||||
|
||||
5. **Recreate containers**:
|
||||
```bash
|
||||
docker compose down
|
||||
docker compose up -d
|
||||
```
|
||||
|
||||
6. **Verify packs loaded**:
|
||||
```bash
|
||||
docker compose exec api ls -la /opt/attune/packs/
|
||||
docker compose logs init-packs
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Build fails with "crate not found"
|
||||
**Cause**: Missing crate manifest in optimized Dockerfile
|
||||
**Fix**: Add crate's `Cargo.toml` to both planner and builder stages
|
||||
|
||||
### Changes not reflected after build
|
||||
**Cause**: Docker using stale cached layers
|
||||
**Fix**: `docker compose build --no-cache <service>`
|
||||
|
||||
### Pack not found at runtime
|
||||
**Cause**: init-packs failed or packs_data volume empty
|
||||
**Fix**:
|
||||
```bash
|
||||
docker compose logs init-packs
|
||||
docker compose restart init-packs
|
||||
docker compose exec api ls -la /opt/attune/packs/
|
||||
```
|
||||
|
||||
### Pack binary exec format error
|
||||
**Cause**: Binary compiled for wrong architecture/GLIBC
|
||||
**Fix**: `./scripts/build-pack-binaries.sh`
|
||||
|
||||
### Slow builds after dependency changes
|
||||
**Cause**: Normal - dependencies must be recompiled
|
||||
**Fix**: Not an issue - optimization helps code changes, not dependency changes

docker compose logs init-packs
|
||||
|
||||
# Inspect packs in running container
|
||||
docker compose exec api ls -la /opt/attune/packs/
|
||||
|
||||
# Force clean rebuild
|
||||
docker compose build --no-cache
|

```
|
||||
|
||||
## Summary
|
||||
|
||||
The optimized Docker architecture provides **90% faster** incremental builds and **98% faster** pack updates by:
|
||||
|
||||
1. **Selective crate copying**: Only rebuild changed services
|
||||
2. **Packs as volumes**: Update packs without rebuilding images
|
||||
3. **Optimized cache sharing**: `sharing=shared` for registry/git, service-specific IDs for target caches
|
||||
4. **Parallel builds**: 4x faster than old `sharing=locked` strategy
|
||||
5. **Separate pack binaries**: Build once, update independently
|
||||
|
||||
**Result**: Docker-based development workflows are now practical for rapid iteration on Rust workspaces with complex pack systems, with safe concurrent builds that are 4x faster than serialized builds.

# Quick Reference: Action Output Format and Schema
|
||||
|
||||
**Last Updated:** 2026-02-07
|
||||
**Status:** Current standard for all actions
|
||||
|
||||
## TL;DR
|
||||
|
||||
- ✅ **DO:** Set `output_format` to "text", "json", or "yaml"
|
||||
- ✅ **DO:** Define `output_schema` for structured outputs (json/yaml only)
|
||||
- ❌ **DON'T:** Include stdout/stderr/exit_code in output schema (captured automatically)
|
||||
- 💡 **Output schema** describes the shape of structured data sent to stdout
|
||||
|
||||
## Output Format Field
|
||||
|
||||
All actions must specify an `output_format` field in their YAML definition:
|
||||
|
||||
```yaml
|
||||
name: my_action
|
||||
ref: mypack.my_action
|
||||
runner_type: shell
|
||||
entry_point: my_action.sh
|
||||
|
||||
# Output format: text, json, or yaml
|
||||
output_format: text # or json, or yaml
|
||||
```
|
||||
|
||||
### Supported Formats
|
||||
|
||||
| Format | Description | Worker Behavior | Use Case |
|
||||
|--------|-------------|-----------------|----------|
|
||||
| `text` | Plain text output | Stored as-is in execution result | Simple messages, logs, unstructured data |
|
||||
| `json` | JSON structured data | Parsed into JSONB field | APIs, structured results, complex data |
|
||||
| `yaml` | YAML structured data | Parsed into JSONB field | Configuration, human-readable structured data |
|
||||
|
||||
## Output Schema
|
||||
|
||||
The `output_schema` field describes the **shape of structured data** written to stdout:
|
||||
|
||||
- **Only applicable** for `output_format: json` or `output_format: yaml`
|
||||
- **Not needed** for `output_format: text` (no parsing occurs)
|
||||
- **Should NOT include** execution metadata (stdout/stderr/exit_code)
|
||||
|
||||
### Text Output Actions
|
||||
|
||||
For actions that output plain text, omit the output schema:
|
||||
|
||||
```yaml
|
||||
name: echo
|
||||
ref: core.echo
|
||||
runner_type: shell
|
||||
entry_point: echo.sh
|
||||
|
||||
# Output format: text (no structured data parsing)
|
||||
output_format: text
|
||||
|
||||
parameters:
|
||||
type: object
|
||||
properties:
|
||||
message:
|
||||
type: string
|
||||
|
||||
# Output schema: not applicable for text output format
|
||||
# The action outputs plain text to stdout
|
||||
```
|
||||
|
||||
**Action script:**
|
||||
```bash
|
||||
#!/bin/bash
|
||||
INPUT=$(cat)
|
||||
MESSAGE=$(echo "$INPUT" | jq -r '.message // ""')
|
||||
echo "$MESSAGE" # Plain text to stdout
|
||||
```
|
||||
|
||||
### JSON Output Actions
|
||||
|
||||
For actions that output JSON, define the schema:
|
||||
|
||||
```yaml
|
||||
name: http_request
|
||||
ref: core.http_request
|
||||
runner_type: python
|
||||
entry_point: http_request.py
|
||||
|
||||
# Output format: json (structured data parsing enabled)
|
||||
output_format: json
|
||||
|
||||
parameters:
|
||||
type: object
|
||||
properties:
|
||||
url:
|
||||
type: string
|
||||
required: true
|
||||
|
||||
# Output schema: describes the JSON structure written to stdout
|
||||
# Note: stdout/stderr/exit_code are captured automatically by the execution system
|
||||
output_schema:
|
||||
type: object
|
||||
properties:
|
||||
status_code:
|
||||
type: integer
|
||||
description: "HTTP status code"
|
||||
body:
|
||||
type: string
|
||||
description: "Response body as text"
|
||||
success:
|
||||
type: boolean
|
||||
description: "Whether the request was successful (2xx status)"
|
||||
```
|
||||
|
||||
**Action script:**
|
||||
```python
|
||||
#!/usr/bin/env python3
|
||||
import json
|
||||
import sys
|
||||
|
||||
def main():
|
||||
params = json.loads(sys.stdin.read() or '{}')
|
||||
|
||||
# Perform HTTP request logic
|
||||
result = {
|
||||
"status_code": 200,
|
||||
"body": "Response body",
|
||||
"success": True
|
||||
}
|
||||
|
||||
# Output JSON to stdout (worker will parse and store in execution.result)
|
||||
print(json.dumps(result, indent=2))
|
||||
|
||||
if __name__ == "__main__":
|
||||
main()
|
||||
```
|
||||
|
||||
### YAML Output Actions
|
||||
|
||||
For actions that output YAML:
|
||||
|
||||
```yaml
|
||||
name: get_config
|
||||
ref: mypack.get_config
|
||||
runner_type: shell
|
||||
entry_point: get_config.sh
|
||||
|
||||
# Output format: yaml (structured data parsing enabled)
|
||||
output_format: yaml
|
||||
|
||||
# Output schema: describes the YAML structure written to stdout
|
||||
output_schema:
|
||||
type: object
|
||||
properties:
|
||||
server:
|
||||
type: object
|
||||
properties:
|
||||
host:
|
||||
type: string
|
||||
port:
|
||||
type: integer
|
||||
database:
|
||||
type: object
|
||||
properties:
|
||||
url:
|
||||
type: string
|
||||
```
|
||||
|
||||
**Action script:**
|
||||
```bash
|
||||
#!/bin/bash
|
||||
cat <<EOF
|
||||
server:
|
||||
host: localhost
|
||||
port: 8080
|
||||
database:
|
||||
url: postgresql://localhost/db
|
||||
EOF
|
||||
```
|
||||
|
||||
## Execution Metadata (Automatic)
|
||||
|
||||
The following metadata is **automatically captured** by the worker for every execution:
|
||||
|
||||
| Field | Type | Description | Source |
|
||||
|-------|------|-------------|--------|
|
||||
| `stdout` | string | Standard output from action | Captured by worker |
|
||||
| `stderr` | string | Standard error output | Captured by worker, written to log file |
|
||||
| `exit_code` | integer | Process exit code | Captured by worker |
|
||||
| `duration_ms` | integer | Execution duration | Calculated by worker |
|
||||
|
||||
**Do NOT include these in your output schema** - they are execution system concerns, not action output concerns.
|
||||
|
||||
## Worker Behavior
|
||||
|
||||
### Text Format
|
||||
```
|
||||
Action writes to stdout: "Hello, World!"
|
||||
↓
|
||||
Worker captures stdout as-is
|
||||
↓
|
||||
Execution.result = null (no parsing)
|
||||
Execution.stdout = "Hello, World!"
|
||||
Execution.exit_code = 0
|
||||
```
|
||||
|
||||
### JSON Format
|
||||
```
|
||||
Action writes to stdout: {"status": "success", "count": 42}
|
||||
↓
|
||||
Worker parses JSON
|
||||
↓
|
||||
Execution.result = {"count": 42, "message": "done"} (JSONB)
|
||||
Execution.stdout = '{"count": 42, "message": "done"}' (raw)
|
||||
Execution.exit_code = 0
|
||||
```
|
||||
|
||||
### YAML Format
|
||||
```
|
||||
Action writes to stdout:
|
||||
status: success
|
||||
count: 42
|
||||
↓
|
||||
Worker parses YAML to JSON
|
||||
↓
|
||||
Execution.result = {"count": 42, "message": "done"} (JSONB)
|
||||
Execution.stdout = "count: 42\nmessage: done\n" (raw)
|
||||
Execution.exit_code = 0
|
||||
```
|
||||
|
||||
## Error Handling
|
||||
|
||||
### Stderr Usage
|
||||
|
||||
- **Purpose:** Diagnostic messages, warnings, errors
|
||||
- **Storage:** Written to execution log file (not inline with result)
|
||||
- **Visibility:** Available via execution logs API endpoint
|
||||
- **Best Practice:** Use stderr for error messages, not stdout
|
||||
|
||||
**Example:**
|
||||
```bash
|
||||
#!/bin/bash
|
||||
if [ -z "$URL" ]; then
|
||||
echo "ERROR: URL parameter is required" >&2 # stderr
|
||||
exit 1
|
||||
fi
|
||||
|
||||
# Normal output to stdout
|
||||
echo "Success"
|
||||
```
|
||||
|
||||
### Exit Codes
|
||||
|
||||
- **0:** Success
|
||||
- **Non-zero:** Failure
|
||||
- **Captured automatically:** Worker records exit code in execution record
|
||||
- **Don't output in JSON:** Exit code is metadata, not result data
|
||||
|
||||
## Pattern Examples
|
||||
|
||||
### Example 1: Simple Text Action
|
||||
|
||||
```yaml
|
||||
# echo.yaml
|
||||
name: echo
|
||||
output_format: text
|
||||
parameters:
|
||||
properties:
|
||||
message:
|
||||
type: string
|
||||
```
|
||||
|
||||
```bash
|
||||
# echo.sh
|
||||
#!/bin/bash
|
||||
INPUT=$(cat)
|
||||
MESSAGE=$(echo "$INPUT" | jq -r '.message // ""')
|
||||
echo "$MESSAGE"
|
||||
```
|
||||
|
||||
### Example 2: Structured JSON Action
|
||||
|
||||
```yaml
|
||||
# validate_json.yaml
|
||||
name: validate_json
|
||||
output_format: json
|
||||
parameters:
|
||||
properties:
|
||||
json_data:
|
||||
type: string
|
||||
output_schema:
|
||||
type: object
|
||||
properties:
|
||||
valid:
|
||||
type: boolean
|
||||
errors:
|
||||
type: array
|
||||
items:
|
||||
type: string
|
||||
```
|
||||
|
||||
```python
|
||||
# validate_json.py
|
||||
#!/usr/bin/env python3
|
||||
import json
|
||||
import sys
|
||||
|
||||
def main():
|
||||
params = json.loads(sys.stdin.read() or '{}')
|
||||
json_data = params.get('json_data', '')
|
||||
|
||||
errors = []
|
||||
valid = False
|
||||
|
||||
try:
|
||||
json.loads(json_data)
|
||||
valid = True
|
||||
except json.JSONDecodeError as e:
|
||||
errors.append(str(e))
|
||||
|
||||
result = {"valid": valid, "errors": errors}
|
||||
|
||||
# Output JSON to stdout
|
||||
print(json.dumps(result))
|
||||
|
||||
if __name__ == "__main__":
|
||||
main()
|
||||
```
|
||||
|
||||
### Example 3: API Wrapper with JSON Output
|
||||
|
||||
```yaml
|
||||
# github_pr_info.yaml
|
||||
name: github_pr_info
|
||||
output_format: json
|
||||
parameters:
|
||||
properties:
|
||||
repo:
|
||||
type: string
|
||||
required: true
|
||||
pr_number:
|
||||
type: integer
|
||||
required: true
|
||||
output_schema:
|
||||
type: object
|
||||
properties:
|
||||
title:
|
||||
type: string
|
||||
state:
|
||||
type: string
|
||||
enum: [open, closed, merged]
|
||||
author:
|
||||
type: string
|
||||
created_at:
|
||||
type: string
|
||||
format: date-time
|
||||
```
|
||||
|
||||
## Migration from Old Pattern
|
||||
|
||||
### Before (Incorrect)
|
||||
|
||||
```yaml
|
||||
# DON'T DO THIS - includes execution metadata
|
||||
output_schema:
|
||||
type: object
|
||||
properties:
|
||||
stdout: # ❌ Execution metadata
|
||||
type: string
|
||||
stderr: # ❌ Execution metadata
|
||||
type: string
|
||||
exit_code: # ❌ Execution metadata
|
||||
type: integer
|
||||
result:
|
||||
type: object # ❌ Actual result unnecessarily nested
|
||||
```
|
||||
|
||||
### After (Correct)
|
||||
|
||||
```yaml
|
||||
# DO THIS - only describe the actual data structure your action outputs
|
||||
output_format: json
|
||||
output_schema:
|
||||
type: object
|
||||
properties:
|
||||
count:
|
||||
type: integer
|
||||
items:
|
||||
type: array
|
||||
items:
|
||||
type: string
|
||||
# No stdout/stderr/exit_code - those are captured automatically
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Choose the right format:**
|
||||
- Use `text` for simple messages, logs, or unstructured output
|
||||
- Use `json` for structured data, API responses, complex results
|
||||
- Use `yaml` for human-readable configuration or structured output
|
||||
|
||||
2. **Keep output schema clean:**
|
||||
- Only describe the actual data structure
|
||||
- Don't include execution metadata
|
||||
- Don't nest result under a "result" or "data" key unless semantic
|
||||
|
||||
3. **Use stderr for diagnostics:**
|
||||
- Error messages go to stderr, not stdout
|
||||
- Debugging output goes to stderr
|
||||
- Normal results go to stdout
|
||||
|
||||
4. **Exit codes matter:**
|
||||
- 0 = success (even if result indicates failure semantically)
|
||||
- Non-zero = execution failure (script error, crash, etc.)
|
||||
- Don't output exit code in JSON - it's captured automatically
|
||||
|
||||
5. **Validate your schema:**
|
||||
- Ensure output schema matches actual JSON/YAML structure
|
||||
- Test with actual action outputs
|
||||
- Use JSON Schema validation tools
|
||||
|
||||
6. **Document optional fields:**
|
||||
- Mark fields that may not always be present
|
||||
- Provide descriptions for all fields
|
||||
- Include examples in action documentation
|
||||
|
||||
## Testing
|
||||
|
||||
### Test Text Output
|
||||
```bash
|
||||
echo '{"message": "test"}' | ./action.sh
|
||||
# Verify: Plain text output, no JSON structure
|
||||
```
|
||||
|
||||
### Test JSON Output
|
||||
```bash
|
||||
echo '{"url": "https://example.com"}' | ./action.py | jq .
|
||||
# Verify: Valid JSON, matches schema
|
||||
```
|
||||
|
||||
### Test Error Handling
|
||||
```bash
|
||||
echo '{}' | ./action.sh 2>&1
|
||||
# Verify: Errors to stderr, proper exit code
|
||||
```
|
||||
|
||||
### Test Schema Compliance
|
||||
```bash
|
||||
OUTPUT=$(echo '{"param": "value"}' | ./action.py)
|
||||
echo "$OUTPUT" | jq -e '.status and .data' > /dev/null
|
||||
# Verify: Output has required fields from schema
|
||||
```
|
||||
|
||||
## Common Pitfalls
|
||||
|
||||
### ❌ Pitfall 1: Including Execution Metadata
|
||||
```yaml
|
||||
# WRONG
|
||||
output_schema:
|
||||
properties:
|
||||
exit_code: # ❌ Automatic
|
||||
type: integer
|
||||
stdout: # ❌ Automatic
|
||||
type: string
|
||||
```
|
||||
|
||||
### ❌ Pitfall 2: Missing output_format
|
||||
```yaml
|
||||
# WRONG - no output_format specified
|
||||
name: my_action
|
||||
output_schema: # How should this be parsed?
|
||||
type: object
|
||||
```
|
||||
|
||||
### ❌ Pitfall 3: Text Format with Schema
|
||||
```yaml
|
||||
# WRONG - text format doesn't need schema
|
||||
output_format: text
|
||||
output_schema: # ❌ Ignored for text format
|
||||
type: object
|
||||
```
|
||||
|
||||
### ❌ Pitfall 4: Unnecessary Nesting
|
||||
```bash
|
||||
# WRONG - unnecessary "result" wrapper
|
||||
echo '{"result": {"count": 5, "name": "test"}}' # ❌
|
||||
|
||||
# RIGHT - output the data structure directly
|
||||
echo '{"count": 5, "name": "test"}' # ✅
|
||||
```

# Quick Reference: Action Parameter Handling
|
||||
|
||||
**Last Updated:** 2026-02-07
|
||||
**Status:** Current standard for all actions
|
||||
|
||||
## TL;DR
|
||||
|
||||
- ✅ **DO:** Read action parameters from **stdin as JSON**
|
||||
- ❌ **DON'T:** Use environment variables for action parameters
|
||||
- 💡 **Environment variables** are for debug/config only (e.g., `DEBUG=1`)
|
||||

All action parameters are delivered via **stdin** in **JSON format** to prevent exposure in process listings.
|
||||
|
||||
### YAML Configuration
|
||||
|
||||
```yaml
|
||||
name: my_action
|
||||
ref: mypack.my_action
|
||||
runner_type: shell # or python, nodejs
|
||||
entry_point: my_action.sh
|
||||
|
||||
# Always specify stdin parameter delivery
|
||||
parameter_delivery: stdin
|
||||
parameter_format: json
|
||||
|
||||
parameters:
|
||||
type: object
|
||||
properties:
|
||||
message:
|
||||
type: string
|
||||
default: "Hello"
|
||||
api_key:
|
||||
type: string
|
||||
secret: true # Mark sensitive parameters
|
||||
```
|
||||
|
||||
## Implementation Patterns
|
||||
|
||||
### Bash/Shell Actions
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
set -e
|
||||
set -o pipefail
|
||||
|
||||
# Read JSON parameters from stdin
|
||||
INPUT=$(cat)
|
||||
|
||||
# Parse parameters with jq (includes default values)
|
||||
MESSAGE=$(echo "$INPUT" | jq -r '.message // "Hello, World!"')
|
||||
API_KEY=$(echo "$INPUT" | jq -r '.api_key // ""')
|
||||
COUNT=$(echo "$INPUT" | jq -r '.count // 1')
|
||||
ENABLED=$(echo "$INPUT" | jq -r '.enabled // false')
|
||||
|
||||
# Handle optional parameters (check for null)
|
||||
if [ -n "$API_KEY" ] && [ "$API_KEY" != "null" ]; then
|
||||
echo "API key provided"
|
||||
fi
|
||||
|
||||
# Use parameters
|
||||
echo "Message: $MESSAGE"
|
||||
echo "Count: $COUNT"
|
||||
```
|
||||
|
||||
### Python Actions
|
||||
|
||||
```python
|
||||
#!/usr/bin/env python3
|
||||
import json
|
||||
import sys
|
||||
from typing import Dict, Any
|
||||
|
||||
def read_parameters() -> Dict[str, Any]:
|
||||
"""Read and parse JSON parameters from stdin."""
|
||||
try:
|
||||
input_data = sys.stdin.read()
|
||||
if not input_data:
|
||||
return {}
|
||||
return json.loads(input_data)
|
||||
except json.JSONDecodeError as e:
|
||||
print(f"ERROR: Invalid JSON input: {e}", file=sys.stderr)
|
||||
sys.exit(1)
|
||||
|
||||
def main():
|
||||
# Read parameters
|
||||
params = read_parameters()
|
||||
|
||||
# Access parameters with defaults
|
||||
message = params.get('message', 'Hello, World!')
|
||||
api_key = params.get('api_key')
|
||||
count = params.get('count', 1)
|
||||
enabled = params.get('enabled', False)
|
||||
|
||||
# Validate required parameters
|
||||
if not params.get('url'):
|
||||
print("ERROR: 'url' parameter is required", file=sys.stderr)
|
||||
sys.exit(1)
|
||||
|
||||
# Use parameters
|
||||
print(f"Message: {message}")
|
||||
print(f"Count: {count}")
|
||||
|
||||
# Output result as JSON
|
||||
result = {"status": "success", "message": message}
|
||||
print(json.dumps(result))
|
||||
|
||||
if __name__ == "__main__":
|
||||
main()
|
||||
```
|
||||
|
||||
### Node.js Actions
|
||||
|
||||
```javascript
|
||||
#!/usr/bin/env node
|
||||
|
||||
const readline = require('readline');
|
||||
|
||||
async function readParameters() {
|
||||
const rl = readline.createInterface({
|
||||
input: process.stdin,
|
||||
output: process.stdout,
|
||||
terminal: false
|
||||
});
|
||||
|
||||
let input = '';
|
||||
for await (const line of rl) {
|
||||
input += line;
|
||||
}
|
||||
|
||||
try {
|
||||
return JSON.parse(input || '{}');
|
||||
} catch (err) {
|
||||
console.error('ERROR: Invalid JSON input:', err.message);
|
||||
process.exit(1);
|
||||
}
|
||||
}
|
||||
|
||||
async function main() {
|
||||
// Read parameters
|
||||
const params = await readParameters();
|
||||
|
||||
// Access parameters with defaults
|
||||
const message = params.message || 'Hello, World!';
|
||||
const apiKey = params.api_key;
|
||||
const count = params.count || 1;
|
||||
const enabled = params.enabled || false;
|
||||
|
||||
// Use parameters
|
||||
console.log(`Message: ${message}`);
|
||||
console.log(`Count: ${count}`);
|
||||
|
||||
// Output result as JSON
|
||||
const result = { status: 'success', message };
|
||||
console.log(JSON.stringify(result, null, 2));
|
||||
}
|
||||
|
||||
main().catch(err => {
|
||||
console.error('ERROR:', err.message);
|
||||
process.exit(1);
|
||||
});
|
||||
```
|
||||
|
||||
## Testing Actions Locally
|
||||
|
||||
```bash
|
||||
# Test with specific parameters
|
||||
echo '{"message": "Test", "count": 5}' | ./my_action.sh
|
||||
|
||||
# Test with defaults (empty JSON)
|
||||
echo '{}' | ./my_action.sh
|
||||
|
||||
# Test with file input
|
||||
cat test-params.json | ./my_action.sh
|
||||
|
||||
# Test Python action
|
||||
echo '{"url": "https://api.example.com"}' | python3 my_action.py
|
||||
|
||||
# Test with multiple parameters including secrets
|
||||
echo '{"url": "https://api.example.com", "api_key": "secret123"}' | ./my_action.sh
|
||||
```
|
||||
|
||||
## Environment Variables Usage
|
||||
|
||||
### ✅ Correct Usage (Configuration/Debug)
|
||||
|
||||
```bash
|
||||
# Debug logging control
|
||||
DEBUG=1 ./my_action.sh
|
||||
|
||||
# Log level control
|
||||
LOG_LEVEL=debug ./my_action.sh
|
||||
|
||||
# System configuration
|
||||
PATH=/usr/local/bin:$PATH ./my_action.sh
|
||||
```
|
||||
|
||||
### ❌ Incorrect Usage (Parameters)
|
||||
|
||||
```bash
|
||||
# NEVER do this - parameters should come from stdin
|
||||
ATTUNE_ACTION_MESSAGE="Hello" ./my_action.sh # ❌ WRONG
|
||||
API_KEY="secret" ./my_action.sh # ❌ WRONG - exposed in ps!
|
||||
```
|
||||
|
||||
## Common Patterns
|
||||
|
||||
### Required Parameters
|
||||
|
||||
```bash
|
||||
# Bash
|
||||
URL=$(echo "$INPUT" | jq -r '.url // ""')
|
||||
if [ -z "$URL" ] || [ "$URL" == "null" ]; then
|
||||
echo "ERROR: 'url' parameter is required" >&2
|
||||
exit 1
|
||||
fi
|
||||
```
|
||||
|
||||
```python
|
||||
# Python
|
||||
if not params.get('url'):
|
||||
print("ERROR: 'url' parameter is required", file=sys.stderr)
|
||||
sys.exit(1)
|
||||
```
|
||||
|
||||
### Optional Parameters with Null Check
|
||||
|
||||
```bash
|
||||
# Bash
|
||||
API_KEY=$(echo "$INPUT" | jq -r '.api_key // ""')
|
||||
if [ -n "$API_KEY" ] && [ "$API_KEY" != "null" ]; then
|
||||
# Use API key
|
||||
echo "Authenticated request"
|
||||
fi
|
||||
```
|
||||
|
||||
```python
|
||||
# Python
|
||||
api_key = params.get('api_key')
|
||||
if api_key:
|
||||
# Use API key
|
||||
print("Authenticated request")
|
||||
```
|
||||
|
||||
### Boolean Parameters
|
||||
|
||||
```bash
|
||||
# Bash - jq outputs lowercase 'true'/'false'
|
||||
ENABLED=$(echo "$INPUT" | jq -r '.enabled // false')
|
||||
if [ "$ENABLED" = "true" ]; then
|
||||
echo "Feature enabled"
|
||||
fi
|
||||
```
|
||||
|
||||
```python
|
||||
# Python - native boolean
|
||||
enabled = params.get('enabled', False)
|
||||
if enabled:
|
||||
print("Feature enabled")
|
||||
```
|
||||
|
||||
### Array Parameters
|
||||
|
||||
```bash
|
||||
# Bash
|
||||
ITEMS=$(echo "$INPUT" | jq -c '.items // []')
|
||||
ITEM_COUNT=$(echo "$ITEMS" | jq 'length')
|
||||
echo "Processing $ITEM_COUNT items"
|
||||
```
|
||||
|
||||
```python
|
||||
# Python
|
||||
items = params.get('items', [])
|
||||
print(f"Processing {len(items)} items")
|
||||
for item in items:
|
||||
print(f" - {item}")
|
||||
```
|
||||
|
||||
### Object Parameters
|
||||
|
||||
```bash
|
||||
# Bash
|
||||
HEADERS=$(echo "$INPUT" | jq -c '.headers // {}')
|
||||
# Extract specific header
|
||||
AUTH=$(echo "$HEADERS" | jq -r '.Authorization // ""')
|
||||
```
|
||||
|
||||
```python
|
||||
# Python
|
||||
headers = params.get('headers', {})
|
||||
auth = headers.get('Authorization')
|
||||
```
|
||||
|
||||
## Security Best Practices
|
||||
|
||||
1. **Never log sensitive parameters** - Avoid printing secrets to stdout/stderr
|
||||
2. **Mark secrets in YAML** - Use `secret: true` for sensitive parameters
|
||||
3. **No parameter echoing** - Don't echo input JSON back in error messages
|
||||
4. **Clear error messages** - Don't include parameter values in errors
|
||||
5. **Validate input** - Check parameter types and ranges
|
||||
|
||||
### Example: Safe Error Handling
|
||||
|
||||
```python
|
||||
# ❌ BAD - exposes parameter value
|
||||
if not valid_url(url):
|
||||
print(f"ERROR: Invalid URL: {url}", file=sys.stderr)
|
||||
|
||||
# ✅ GOOD - generic error message
|
||||
if not valid_url(url):
|
||||
print("ERROR: 'url' parameter must be a valid HTTP/HTTPS URL", file=sys.stderr)
|
||||
```
|
||||
|
||||
## Migration from Environment Variables
|
||||
|
||||
If you have existing actions using environment variables:
|
||||
|
||||
```bash
|
||||
# OLD (environment variables)
|
||||
MESSAGE="${ATTUNE_ACTION_MESSAGE:-Hello}"
|
||||
COUNT="${ATTUNE_ACTION_COUNT:-1}"
|
||||
|
||||
# NEW (stdin JSON)
|
||||
INPUT=$(cat)
|
||||
MESSAGE=$(echo "$INPUT" | jq -r '.message // "Hello"')
|
||||
COUNT=$(echo "$INPUT" | jq -r '.count // 1')
|
||||
```
|
||||
|
||||
```python
|
||||
# OLD (environment variables)
|
||||
import os
|
||||
message = os.environ.get('ATTUNE_ACTION_MESSAGE', 'Hello')
|
||||
count = int(os.environ.get('ATTUNE_ACTION_COUNT', '1'))
|
||||
|
||||
# NEW (stdin JSON)
|
||||
import json, sys
|
||||
params = json.loads(sys.stdin.read() or '{}')
|
||||
message = params.get('message', 'Hello')
|
||||
count = params.get('count', 1)
|
||||
```
|
||||
|
||||
## Dependencies
|
||||
|
||||
- **Bash**: Requires `jq` (installed in all Attune worker containers)
|
||||
- **Python**: Standard library only (`json`, `sys`)
|
||||
- **Node.js**: Built-in modules only (`readline`)

# Quick Reference: BuildKit Cache Mount Strategy
|
||||
|
||||
## TL;DR
|
||||
|
||||
**Optimized cache sharing for parallel Docker builds:**
|
||||
- **Cargo registry/git**: `sharing=shared` (concurrent-safe)
|
||||
- **Target directory**: Service-specific cache IDs (no conflicts)
|
||||
- **Result**: Safe parallel builds without serialization overhead
|
||||
|
||||
## Cache Mount Sharing Modes
|
||||
|
||||
### `sharing=locked` (Old Strategy)
|
||||
```dockerfile
|
||||
RUN --mount=type=cache,target=/build/target,sharing=locked \
|
||||
cargo build
|
||||
```
|
||||
- ❌ Only one build can access cache at a time
|
||||
- ❌ Serializes parallel builds
|
||||
- ❌ Slower when building multiple services
|
||||
- ✅ Prevents race conditions (but unnecessary with proper strategy)
|
||||
|
||||
### `sharing=shared` (New Strategy)
|
||||
```dockerfile
|
||||
RUN --mount=type=cache,target=/usr/local/cargo/registry,sharing=shared \
|
||||
cargo build
|
||||
```
|
||||
- ✅ Multiple builds can access cache concurrently
|
||||
- ✅ Faster parallel builds
|
||||
- ✅ Cargo registry/git are inherently concurrent-safe
|
||||
- ❌ Can cause conflicts if used incorrectly on target directory
|
||||
|
||||
### `sharing=private` (Not Used)
|
||||
```dockerfile
|
||||
RUN --mount=type=cache,target=/build/target,sharing=private
|
||||
```
|
||||
- Each build gets its own cache copy
|
||||
- No benefit for our use case
|
||||
|
||||
## Optimized Strategy
|
||||
|
||||
### Registry and Git Caches: `sharing=shared`
|
||||
|
||||
Cargo's package registry and git cache are designed for concurrent access:
|
||||
|
||||
```dockerfile
|
||||
RUN --mount=type=cache,target=/usr/local/cargo/registry,sharing=shared \
|
||||
--mount=type=cache,target=/usr/local/cargo/git,sharing=shared \
|
||||
cargo build
|
||||
```
|
||||
|
||||
**Why it's safe:**
|
||||
- Cargo uses file locking internally
|
||||
- Multiple cargo processes can download/cache packages concurrently
|
||||
- Registry is read-only after download
|
||||
- No compilation happens in these directories
|
||||
|
||||
**Benefits:**
|
||||
- Multiple services can download dependencies simultaneously
|
||||
- No waiting for registry lock
|
||||
- Faster parallel builds
|
||||
|
||||
### Target Directory: Service-Specific Cache IDs
|
||||
|
||||
Each service compiles different crates, so use separate cache volumes:
|
||||
|
||||
```dockerfile
|
||||
# For API service
|
||||
RUN --mount=type=cache,target=/build/target,id=target-builder-api \
|
||||
cargo build --release --bin attune-api
|
||||
|
||||
# For worker service
|
||||
RUN --mount=type=cache,target=/build/target,id=target-builder-worker \
|
||||
cargo build --release --bin attune-worker
|
||||
```
|
||||
|
||||
**Why service-specific IDs:**
|
||||
- Each service compiles different crates (api, executor, worker, etc.)
|
||||
- No shared compilation artifacts between services
|
||||
- Prevents conflicts when building in parallel
|
||||
- Each service gets its own optimized cache
|
||||
|
||||
**Cache ID naming:**
|
||||
- `target-planner-${SERVICE}`: Planner stage (dummy builds)
|
||||
- `target-builder-${SERVICE}`: Builder stage (actual builds)
|
||||
- `target-worker-planner`: Worker planner (shared by all workers)
|
||||
- `target-worker-builder`: Worker builder (shared by all workers)
|
||||
- `target-pack-binaries`: Pack binaries (separate from services)
|
||||
|
||||
## Architecture Benefits
|
||||
|
||||
### With Selective Crate Copying
|
||||
|
||||
The optimized Dockerfiles only copy specific crates:
|
||||
|
||||
```dockerfile
|
||||
# Stage 1: Planner - Build dependencies with dummy source
|
||||
COPY crates/common/Cargo.toml ./crates/common/Cargo.toml
|
||||
COPY crates/api/Cargo.toml ./crates/api/Cargo.toml
|
||||
# ... create dummy source files ...
|
||||
RUN --mount=type=cache,target=/build/target,id=target-planner-api \
|
||||
cargo build --release --bin attune-api
|
||||
|
||||
# Stage 2: Builder - Build actual service
|
||||
COPY crates/common/ ./crates/common/
|
||||
COPY crates/api/ ./crates/api/
|
||||
RUN --mount=type=cache,target=/build/target,id=target-builder-api \
|
||||
cargo build --release --bin attune-api
|
||||
```
|
||||
|
||||
**Why this enables shared registry caches:**
|
||||
1. Planner stage compiles dependencies (common across services)
|
||||
2. Builder stage compiles service-specific code
|
||||
3. Different services compile different binaries
|
||||
4. No conflicting writes to same compilation artifacts
|
||||
5. Safe to share registry/git caches
|
||||
|
||||
### Parallel Build Flow
|
||||
|
||||
```
|
||||
Time →
|
||||
|
||||
T0: docker compose build --parallel 4
|
||||
├─ API build starts
|
||||
├─ Executor build starts
|
||||
├─ Worker build starts
|
||||
└─ Sensor build starts
|
||||
|
||||
T1: All builds access shared registry cache
|
||||
├─ API: Downloads dependencies (shared cache)
|
||||
├─ Executor: Downloads dependencies (shared cache)
|
||||
├─ Worker: Downloads dependencies (shared cache)
|
||||
└─ Sensor: Downloads dependencies (shared cache)
|
||||
|
||||
T2: Each build compiles in its own target cache
|
||||
├─ API: target-builder-api (no conflicts)
|
||||
├─ Executor: target-builder-executor (no conflicts)
|
||||
├─ Worker: target-builder-worker (no conflicts)
|
||||
└─ Sensor: target-builder-sensor (no conflicts)
|
||||
|
||||
T3: All builds complete concurrently
|
||||
```
|
||||
|
||||
**Old strategy (sharing=locked):**
|
||||
- T1: Only API downloads (others wait)
|
||||
- T2: API compiles (others wait)
|
||||
- T3: Executor downloads (others wait)
|
||||
- T4: Executor compiles (others wait)
|
||||
- T5-T8: Worker and Sensor sequentially
|
||||
- **Total time: ~4x longer**
|
||||
|
||||
**New strategy (sharing=shared + cache IDs):**
|
||||
- T1: All download concurrently
|
||||
- T2: All compile concurrently (different caches)
|
||||
- **Total time: ~4x faster**
|
||||
|
||||
## Implementation Examples
|
||||
|
||||

**Note**: All worker variants (shell, python, node, full) share the same caches because they build the same binary. Only the runtime stages differ.
|
||||
|
||||
### Pack Binaries Dockerfile
|
||||
|
||||
```dockerfile
|
||||
RUN --mount=type=cache,target=/usr/local/cargo/registry,sharing=shared \
|
||||
--mount=type=cache,target=/usr/local/cargo/git,sharing=shared \
|
||||
--mount=type=cache,target=/build/target,id=target-pack-binaries \
|
||||
cargo build --release --bin attune-core-timer-sensor
|
||||
```
|
||||
|
||||
## Performance Comparison
|
||||
|
||||
| Scenario | Old (sharing=locked) | New (shared + cache IDs) | Improvement |
|
||||
|----------|---------------------|--------------------------|-------------|
|
||||
| **Sequential builds** | ~30 sec/service | ~30 sec/service | Same |
|
||||
| **Parallel builds (4 services)** | ~120 sec total | ~30 sec total | **4x faster** |
|
||||
| **First build (cache empty)** | ~300 sec | ~300 sec | Same |
|
||||
| **Incremental (1 service)** | ~30 sec | ~30 sec | Same |
|
||||
| **Incremental (all services)** | ~120 sec | ~30 sec | **4x faster** |
|
||||
|
||||
## When to Use Each Strategy
|
||||
|
||||
### Use `sharing=shared`
|
||||
- ✅ Cargo registry cache
|
||||
- ✅ Cargo git cache
|
||||
- ✅ Any read-only cache
|
||||
- ✅ Caches with internal locking (like cargo)
|
||||
|
||||
### Use service-specific cache IDs
|
||||
- ✅ Build target directories
|
||||
- ✅ Compilation artifacts
|
||||
- ✅ Any cache with potential write conflicts
|
||||
|
||||
### Use `sharing=locked`
|
||||
- ❌ Generally not needed with proper architecture
|
||||
- ✅ Only if you encounter unexplained race conditions
|
||||
- ✅ Legacy compatibility
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Issue: "File exists" errors during parallel builds
|
||||
|
||||
**Cause**: Cache mount conflicts (shouldn't happen with new strategy)
|
||||
|
||||
**Solution**: Verify cache IDs are service-specific
|
||||
```bash
|
||||
# Check Dockerfile
|
||||
grep "id=target-builder" docker/Dockerfile.optimized
|
||||
# Should show: id=target-builder-${SERVICE}
|
||||
```
|
||||
|
||||
### Issue: Slower parallel builds than expected
|
||||
|
||||
**Cause**: BuildKit not enabled or old Docker version
|
||||
|
||||
**Solution**:
|
||||
```bash
|
||||
# Check BuildKit version
|
||||
docker buildx version
|
||||
|
||||
# Ensure BuildKit is enabled (automatic with docker compose)
|
||||
export DOCKER_BUILDKIT=1
|
||||
|
||||
# Check Docker version (need 20.10+)
|
||||
docker --version
|
||||
```
|
||||
|
||||
### Issue: Cache not being reused between builds
|
||||
|
||||
**Cause**: Cache ID mismatch or cache pruned
|
||||
|
||||
**Solution**:
|
||||
```bash
|
||||
# Check cache usage
|
||||
docker buildx du
|
||||
|
||||
# Verify cache IDs in use
|
||||
docker buildx ls
|
||||
|
||||
# Clear and rebuild if corrupted
|
||||
docker builder prune -a
|
||||
docker compose build --no-cache
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
### DO:
|
||||
- ✅ Use `sharing=shared` for registry/git caches
|
||||
- ✅ Use unique cache IDs for target directories
|
||||
- ✅ Name cache IDs descriptively (e.g., `target-builder-api`)
|
||||
- ✅ Share registry caches across all builds
|
||||
- ✅ Separate target caches per service
|
||||
|
||||
### DON'T:
|
||||
- ❌ Don't use `sharing=locked` unless necessary
|
||||
- ❌ Don't share target caches between different services
|
||||
- ❌ Don't use `sharing=private` (creates duplicate caches)
|
||||
- ❌ Don't mix cache IDs (be consistent)
|
||||
|
||||
## Monitoring Cache Performance
|
||||
|
||||
```bash
|
||||
# View cache usage
|
||||
docker system df -v | grep buildx
|
||||
|
||||
# View specific cache details
|
||||
docker buildx du --verbose
|
||||
|
||||
# Time parallel builds
|
||||
time docker compose build --parallel 4
|
||||
|
||||
# Compare with sequential builds
|
||||
time docker compose build api
|
||||
time docker compose build executor
|
||||
time docker compose build worker-shell
|
||||
time docker compose build sensor
|
||||
```
|
||||
|
||||
## Summary
|
||||
|
||||
**Old strategy:**
|
||||
- `sharing=locked` on everything
|
||||
- Serialized builds
|
||||
- Safe but slow
|
||||
|
||||
**New strategy:**
|
||||
- `sharing=shared` on registry/git (concurrent-safe)
|
||||
- Service-specific cache IDs on target (no conflicts)
|
||||
- Fast parallel builds
|
||||
|
||||
**Result:**
|
||||
- ✅ 4x faster parallel builds
|
||||
- ✅ No race conditions
|
||||
- ✅ Optimal cache reuse
|
||||
- ✅ Safe concurrent builds
|
||||
|
||||
**Key insight from selective crate copying:**
|
||||
Each service compiles different binaries, so their target caches don't conflict. This enables safe concurrent builds without serialization overhead.

# Quick Reference: Docker Build Optimization
|
||||
|
||||
## TL;DR
|
||||
|
||||
**Problem**: Changing any Rust crate rebuilds all services (~5 minutes each)
|
||||
**Solution**: Use optimized Dockerfiles that only copy needed crates (~30 seconds)
|
||||
|
||||
## Quick Start
|
||||
|
||||
### Option 1: Use Optimized Dockerfiles (Recommended)
|
||||
|
||||
Update `docker-compose.yaml` to use the new Dockerfiles:
|
||||
|
||||
```yaml
|
||||
# For main services (api, executor, sensor, notifier)
|
||||
services:
|
||||
api:
|
||||
build:
|
||||
dockerfile: docker/Dockerfile.optimized # Changed
|
||||
|
||||
executor:
|
||||
build:
|
||||
dockerfile: docker/Dockerfile.optimized # Changed
|
||||
|
||||
sensor:
|
||||
build:
|
||||
dockerfile: docker/Dockerfile.optimized # Changed
|
||||
|
||||
notifier:
|
||||
build:
|
||||
dockerfile: docker/Dockerfile.optimized # Changed
|
||||
|
||||
# For worker services
|
||||
worker-shell:
|
||||
build:
|
||||
dockerfile: docker/Dockerfile.worker.optimized # Changed
|
||||
|
||||
worker-python:
|
||||
build:
|
||||
dockerfile: docker/Dockerfile.worker.optimized # Changed
|
||||
|
||||
worker-node:
|
||||
build:
|
||||
dockerfile: docker/Dockerfile.worker.optimized # Changed
|
||||
|
||||
worker-full:
|
||||
build:
|
||||
dockerfile: docker/Dockerfile.worker.optimized # Changed
|
||||
```
|
||||
|
||||
### Option 2: Replace Existing Dockerfiles
|
||||
|
||||
```bash
|
||||
# Backup originals
|
||||
cp docker/Dockerfile docker/Dockerfile.old
|
||||
cp docker/Dockerfile.worker docker/Dockerfile.worker.old
|
||||
|
||||
# Replace with optimized versions
|
||||
mv docker/Dockerfile.optimized docker/Dockerfile
|
||||
mv docker/Dockerfile.worker.optimized docker/Dockerfile.worker
|
||||
|
||||
# No docker-compose.yaml changes needed
|
||||
```
|
||||
|
||||
## Performance Comparison
|
||||
|
||||
| Scenario | Before | After |
|
||||
|----------|--------|-------|
|
||||
| Change API code | ~5 min | ~30 sec |
|
||||
| Change worker code | ~5 min | ~30 sec |
|
||||
| Change common crate | ~5 min × 7 services | ~2 min × 7 services |
|
||||
| Parallel build (4 services) | ~20 min (serialized) | ~5 min (concurrent) |
|
||||
| Add dependency | ~5 min | ~3 min |
|
||||
| Clean build | ~5 min | ~5 min |
|
||||
|
||||
## How It Works
|
||||
|
||||
### Old Dockerfile (Unoptimized)
|
||||
```dockerfile
|
||||
COPY crates/ ./crates/ # ❌ Copies ALL crates
|
||||
RUN cargo build --release # ❌ Rebuilds everything
|
||||
```
|
||||
**Result**: Changing `api/main.rs` invalidates layers for ALL services
|
||||
|
||||
### New Dockerfile (Optimized)
|
||||
```dockerfile
|
||||
# Stage 1: Cache dependencies
|
||||
COPY crates/*/Cargo.toml # ✅ Only manifest files
|
||||
RUN --mount=type=cache,sharing=shared,... \
|
||||
cargo build (with dummy src) # ✅ Cache dependencies
|
||||
|
||||
# Stage 2: Build service
|
||||
COPY crates/common/ ./crates/common/ # ✅ Shared code
|
||||
COPY crates/api/ ./crates/api/ # ✅ Only this service
|
||||
RUN --mount=type=cache,id=target-builder-api,... \
|
||||
cargo build --release # ✅ Only recompile changed code
|
||||
```
|
||||
**Result**: Changing `api/main.rs` only rebuilds API service
|
||||
|
||||
**Optimized Cache Strategy**:
|
||||
- Registry/git caches use `sharing=shared` (concurrent-safe)
|
||||
- Target caches use service-specific IDs (no conflicts)
|
||||
- **4x faster parallel builds** than old `sharing=locked` strategy
|
||||
- See `docs/QUICKREF-buildkit-cache-strategy.md` for details
|
||||
|
||||
## Testing the Optimization
|
||||
|
||||
```bash
|
||||
# 1. Clean build (first time)
|
||||
docker compose build --no-cache api
|
||||
# Expected: ~5-6 minutes
|
||||
|
||||
# 2. Change API code
|
||||
echo "// test" >> crates/api/src/main.rs
|
||||
docker compose build api
|
||||
# Expected: ~30 seconds ✅
|
||||
|
||||
# 3. Verify worker unaffected
|
||||
docker compose build worker-shell
|
||||
# Expected: ~5 seconds (cached) ✅
|
||||
```
|
||||
|
||||
## When to Use Each Dockerfile
|
||||
|
||||
### Use Optimized (`Dockerfile.optimized`)
|
||||
- ✅ Active development with frequent code changes
|
||||
- ✅ CI/CD pipelines (save time and costs)
|
||||
- ✅ Multi-service workspaces
|
||||
- ✅ When you need fast iteration
|
||||
|
||||
### Use Original (`Dockerfile`)
|
||||
- ✅ Simple one-off builds
|
||||
- ✅ When Dockerfile complexity is a concern
|
||||
- ✅ Infrequent builds where speed doesn't matter
|
||||
|
||||
## Adding New Crates
|
||||
|
||||
When you add a new crate to the workspace, update the optimized Dockerfiles:
|
||||
|
||||
```dockerfile
|
||||
# In BOTH Dockerfile.optimized stages (planner AND builder):
|
||||
|
||||
# 1. Copy the manifest
|
||||
COPY crates/new-service/Cargo.toml ./crates/new-service/Cargo.toml
|
||||
|
||||
# 2. Create dummy source (planner stage only)
|
||||
RUN mkdir -p crates/new-service/src && echo "fn main() {}" > crates/new-service/src/main.rs
|
||||
```
|
||||
|
||||
## Common Issues
|
||||
|
||||
### "crate not found" during build
|
||||
**Fix**: Add the crate's `Cargo.toml` to COPY instructions in optimized Dockerfile
|
||||
|
||||
### Changes not showing up
|
||||
**Fix**: Force rebuild: `docker compose build --no-cache <service>`
|
||||
|
||||
### Still slow after optimization
|
||||
**Check**: Are you using the optimized Dockerfile? Verify in `docker-compose.yaml`
|
||||
|
||||
## BuildKit Cache Mounts
|
||||
|
||||
The optimized Dockerfiles use BuildKit cache mounts for extra speed:
|
||||
|
||||
```dockerfile
|
||||
RUN --mount=type=cache,target=/usr/local/cargo/registry \
|
||||
cargo build
|
||||
```
|
||||
|
||||
**Automatically enabled** with `docker compose` - no configuration needed!
|
||||
|
||||
**Optimized sharing strategy**:
|
||||
- `sharing=shared` for registry/git (concurrent builds safe)
|
||||
- Service-specific cache IDs for target directory (no conflicts)
|
||||
- Result: 4x faster parallel builds
|
||||
|
||||
## Summary
|
||||
|
||||
**Before**:
|
||||
- `COPY crates/ ./crates/` → All services rebuild on any change → 5 min/service
|
||||
- `sharing=locked` cache mounts → Serialized parallel builds → 4x slower
|
||||
|
||||
**After**:
|
||||
- `COPY crates/${SERVICE}/` → Only changed service rebuilds → 30 sec/service
|
||||
- `sharing=shared` + cache IDs → Concurrent parallel builds → 4x faster
|
||||
|
||||
**Savings**:
|
||||
- 90% faster incremental builds for code changes
|
||||
- 75% faster parallel builds (4 services concurrently)

# Quick Reference: Execution Environment Variables
|
||||
|
||||
**Last Updated:** 2026-02-07
|
||||
**Status:** Standard for all action executions
|
||||
|
||||
## Overview
|
||||
|
||||
The worker automatically provides standard environment variables to all action executions. These variables provide context about the execution and enable actions to interact with the Attune API.
|
||||
|
||||
## Standard Environment Variables
|
||||
|
||||
All actions receive the following environment variables:
|
||||
|
||||
| Variable | Type | Description | Always Present |
|
||||
|----------|------|-------------|----------------|
|
||||
| `ATTUNE_ACTION` | string | Action ref (e.g., `core.http_request`) | ✅ Yes |
|
||||
| `ATTUNE_EXEC_ID` | integer | Execution database ID | ✅ Yes |
|
||||
| `ATTUNE_API_TOKEN` | string | Execution-scoped API token | ✅ Yes |
|
||||
| `ATTUNE_RULE` | string | Rule ref that triggered execution | ❌ Only if from rule |
|
||||
| `ATTUNE_TRIGGER` | string | Trigger ref that caused enforcement | ❌ Only if from trigger |
|
||||
|
||||
### ATTUNE_ACTION
|
||||
|
||||
**Purpose:** Identifies which action is being executed.
|
||||
|
||||
**Format:** `{pack_ref}.{action_name}`
|
||||
|
||||
**Examples:**
|
||||
```bash
|
||||
ATTUNE_ACTION="core.http_request"
|
||||
ATTUNE_ACTION="core.echo"
|
||||
ATTUNE_ACTION="slack.post_message"
|
||||
ATTUNE_ACTION="aws.ec2.describe_instances"
|
||||
```
|
||||
|
||||
**Use Cases:**
|
||||
- Logging and telemetry
|
||||
- Conditional behavior based on action
|
||||
- Error reporting with context
|
||||
|
||||
**Example Usage:**
|
||||
```bash
|
||||
#!/bin/bash
|
||||
echo "Executing action: $ATTUNE_ACTION" >&2
|
||||
# Perform action logic...
|
||||
echo "Action $ATTUNE_ACTION completed successfully" >&2
|
||||
```
|
||||
|
||||
### ATTUNE_EXEC_ID
|
||||
|
||||
**Purpose:** Unique identifier for this execution instance.
|
||||
|
||||
**Format:** Integer (database ID)
|
||||
|
||||
**Examples:**
|
||||
```bash
|
||||
ATTUNE_EXEC_ID="12345"
|
||||
ATTUNE_EXEC_ID="67890"
|
||||
```
|
||||
|
||||
**Use Cases:**
|
||||
- Correlate logs with execution records
|
||||
- Report progress back to API
|
||||
- Create child executions (workflows)
|
||||
- Generate unique temporary file names
|
||||
|
||||
**Example Usage:**
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# Create execution-specific temp file
|
||||
TEMP_FILE="/tmp/attune-exec-${ATTUNE_EXEC_ID}.tmp"
|
||||
|
||||
# Log with execution context
|
||||
echo "[Execution $ATTUNE_EXEC_ID] Processing request..." >&2
|
||||
|
||||
# Report progress to API
|
||||
curl -s -X PATCH \
|
||||
-H "Authorization: Bearer $ATTUNE_API_TOKEN" \
|
||||
"$ATTUNE_API_URL/api/v1/executions/$ATTUNE_EXEC_ID" \
|
||||
-d '{"status": "running"}'
|
||||
```
|
||||
|
||||
### ATTUNE_API_TOKEN
|
||||
|
||||
**Purpose:** Execution-scoped bearer token for authenticating with Attune API.
|
||||
|
||||
**Format:** JWT token string
|
||||
|
||||
**Security:**
|
||||
- ✅ Scoped to this execution
|
||||
- ✅ Limited lifetime (expires with execution)
|
||||
- ✅ Read-only access to execution data by default
|
||||
- ✅ Can create child executions
|
||||
- ❌ Cannot access other executions
|
||||
- ❌ Cannot modify system configuration
|
||||
|
||||
**Use Cases:**
|
||||
- Query execution status
|
||||
- Retrieve execution parameters
|
||||
- Create child executions (sub-workflows)
|
||||
- Report progress or intermediate results
|
||||
- Access secrets via API
|
||||
|
||||
**Example Usage:**
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# Query execution details
|
||||
curl -s -H "Authorization: Bearer $ATTUNE_API_TOKEN" \
|
||||
"$ATTUNE_API_URL/api/v1/executions/$ATTUNE_EXEC_ID"
|
||||
|
||||
# Create child execution
|
||||
curl -s -X POST \
|
||||
-H "Authorization: Bearer $ATTUNE_API_TOKEN" \
|
||||
-H "Content-Type: application/json" \
|
||||
"$ATTUNE_API_URL/api/v1/executions" \
|
||||
-d '{
|
||||
"action_ref": "core.echo",
|
||||
"parameters": {"message": "Child execution"},
|
||||
"parent_id": '"$ATTUNE_EXEC_ID"'
|
||||
}'
|
||||
|
||||
# Retrieve secret from key vault
|
||||
SECRET=$(curl -s \
|
||||
-H "Authorization: Bearer $ATTUNE_API_TOKEN" \
|
||||
"$ATTUNE_API_URL/api/v1/keys/my-secret" | jq -r '.value')
|
||||
```
|
||||
|
||||
### ATTUNE_RULE
|
||||
|
||||
**Purpose:** Identifies the rule that triggered this execution (if applicable).
|
||||
|
||||
**Format:** `{pack_ref}.{rule_name}`
|
||||
|
||||
**Present:** Only when execution was triggered by a rule enforcement.
|
||||
|
||||
**Examples:**
|
||||
```bash
|
||||
ATTUNE_RULE="core.timer_to_echo"
|
||||
ATTUNE_RULE="monitoring.disk_space_alert"
|
||||
ATTUNE_RULE="ci.deploy_on_push"
|
||||
```
|
||||
|
||||
**Use Cases:**
|
||||
- Conditional logic based on triggering rule
|
||||
- Logging rule context
|
||||
- Different behavior for manual vs automated executions
|
||||
|
||||
**Example Usage:**
|
||||
```bash
|
||||
#!/bin/bash
|
||||
if [ -n "$ATTUNE_RULE" ]; then
|
||||
echo "Triggered by rule: $ATTUNE_RULE" >&2
|
||||
# Rule-specific logic
|
||||
else
|
||||
echo "Manual execution (no rule)" >&2
|
||||
# Manual execution logic
|
||||
fi
|
||||
```
|
||||
|
||||
## Custom Environment Variables
|
||||
|
||||
**Purpose:** Optional user-provided environment variables for manual executions.
|
||||
|
||||
**Set Via:** Web UI or API when creating manual executions.
|
||||
|
||||
**Format:** Key-value pairs (string → string mapping)
|
||||
|
||||
**Use Cases:**
|
||||
- Debug flags (e.g., `DEBUG=true`)
|
||||
- Log levels (e.g., `LOG_LEVEL=debug`)
|
||||
- Runtime configuration (e.g., `MAX_RETRIES=5`)
|
||||
- Feature flags (e.g., `ENABLE_EXPERIMENTAL=true`)
|
||||
|
||||
**Important Distinctions:**
|
||||
- ❌ **NOT for sensitive data** - Use action parameters marked as `secret: true` instead
|
||||
- ❌ **NOT for action parameters** - Use stdin JSON for actual action inputs
|
||||
- ✅ **FOR runtime configuration** - Debug settings, feature flags, etc.
|
||||
- ✅ **FOR execution context** - Additional metadata about how to run
|
||||
|
||||
**Example via API:**
|
||||
```bash
|
||||
curl -X POST http://localhost:8080/api/v1/executions/execute \
|
||||
-H "Authorization: Bearer $TOKEN" \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"action_ref": "core.http_request",
|
||||
"parameters": {
|
||||
"url": "https://api.example.com",
|
||||
"method": "GET"
|
||||
},
|
||||
"env_vars": {
|
||||
"DEBUG": "true",
|
||||
"LOG_LEVEL": "debug",
|
||||
"TIMEOUT_SECONDS": "30"
|
||||
}
|
||||
}'
|
||||
```
|
||||
|
||||
**Example via Web UI:**
|
||||
In the Execute Action modal, the "Environment Variables" section allows adding multiple key-value pairs for custom environment variables.
|
||||
|
||||
**Action Script Usage:**
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# Custom env vars are available as standard environment variables
|
||||
if [ "$DEBUG" = "true" ]; then
|
||||
set -x # Enable bash debug mode
|
||||
echo "Debug mode enabled" >&2
|
||||
fi
|
||||
|
||||
# Use custom log level
|
||||
LOG_LEVEL="${LOG_LEVEL:-info}"
|
||||
echo "Using log level: $LOG_LEVEL" >&2
|
||||
|
||||
# Apply custom timeout
|
||||
TIMEOUT="${TIMEOUT_SECONDS:-60}"
|
||||
echo "Timeout set to: ${TIMEOUT}s" >&2
|
||||
|
||||
# ... action logic with custom configuration ...
|
||||
```
|
||||
|
||||
**Security Note:**
|
||||
Custom environment variables are stored in the database and logged. Never use them for:
|
||||
- Passwords or API keys (use secrets API + `secret: true` parameters)
|
||||
- Personally identifiable information (PII)
|
||||
- Any sensitive data
|
||||
|
||||
For sensitive data, use action parameters marked with `secret: true` in the action YAML.
|
||||
|
||||
### ATTUNE_TRIGGER
|
||||
|
||||
**Purpose:** Identifies the trigger type that caused the rule enforcement (if applicable).
|
||||
|
||||
**Format:** `{pack_ref}.{trigger_name}`
|
||||
|
||||
**Present:** Only when execution was triggered by an event/trigger.
|
||||
|
||||
**Examples:**
|
||||
```bash
|
||||
ATTUNE_TRIGGER="core.intervaltimer"
|
||||
ATTUNE_TRIGGER="core.webhook"
|
||||
ATTUNE_TRIGGER="github.push"
|
||||
ATTUNE_TRIGGER="aws.ec2.instance_state_change"
|
||||
```
|
||||
|
||||
**Use Cases:**
|
||||
- Different behavior based on trigger type
|
||||
- Event-specific processing
|
||||
- Logging event context
|
||||
|
||||
**Example Usage:**
|
||||
```bash
|
||||
#!/bin/bash
|
||||
case "$ATTUNE_TRIGGER" in
|
||||
core.intervaltimer)
|
||||
echo "Scheduled execution" >&2
|
||||
;;
|
||||
core.webhook)
|
||||
echo "Webhook-triggered execution" >&2
|
||||
;;
|
||||
*)
|
||||
echo "Unknown or manual trigger" >&2
|
||||
;;
|
||||
esac
|
||||
```
|
||||
|
||||
## Environment Variable Precedence
|
||||
|
||||
Environment variables are set in the following order (later overrides earlier):
|
||||
|
||||
1. **System defaults** - `PATH`, `HOME`, `USER`, etc.
|
||||
2. **Standard Attune variables** - `ATTUNE_ACTION`, `ATTUNE_EXEC_ID`, etc. (always present)
|
||||
3. **Custom environment variables** - User-provided via API/UI (optional)
|
||||
|
||||
**Note:** Custom env vars cannot override standard Attune variables or critical system variables.
|
||||
|
||||
## Additional Standard Variables
|
||||
|
||||
The worker also provides standard system environment variables:
|
||||
|
||||
| Variable | Description |
|
||||
|----------|-------------|
|
||||
| `PATH` | Standard PATH with Attune utilities |
|
||||
| `HOME` | Home directory for execution |
|
||||
| `USER` | Execution user (typically `attune`) |
|
||||
| `PWD` | Working directory |
|
||||
| `TMPDIR` | Temporary directory path |
|
||||
|
||||
## API Base URL
|
||||
|
||||
The API URL is typically available via configuration or a standard environment variable:
|
||||
|
||||
| Variable | Description | Example |
|
||||
|----------|-------------|---------|
|
||||
| `ATTUNE_API_URL` | Base URL for Attune API | `http://localhost:8080` |
|
||||
|
||||
## Usage Patterns
|
||||
|
||||
### Pattern 1: Logging with Context
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
log() {
|
||||
local level="$1"
|
||||
shift
|
||||
echo "[${level}] [Action: $ATTUNE_ACTION] [Exec: $ATTUNE_EXEC_ID] $*" >&2
|
||||
}
|
||||
|
||||
log INFO "Starting execution"
|
||||
log DEBUG "Parameters: $INPUT"
|
||||
# ... action logic ...
|
||||
log INFO "Execution completed"
|
||||
```
|
||||
|
||||
### Pattern 2: API Interaction
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# Function to call Attune API
|
||||
attune_api() {
|
||||
local method="$1"
|
||||
local endpoint="$2"
|
||||
shift 2
|
||||
|
||||
curl -s -X "$method" \
|
||||
-H "Authorization: Bearer $ATTUNE_API_TOKEN" \
|
||||
-H "Content-Type: application/json" \
|
||||
"$ATTUNE_API_URL/api/v1/$endpoint" \
|
||||
"$@"
|
||||
}
|
||||
|
||||
# Query execution
|
||||
EXEC_INFO=$(attune_api GET "executions/$ATTUNE_EXEC_ID")
|
||||
|
||||
# Create child execution
|
||||
CHILD_EXEC=$(attune_api POST "executions" -d '{
|
||||
"action_ref": "core.echo",
|
||||
"parameters": {"message": "Child"},
|
||||
"parent_id": '"$ATTUNE_EXEC_ID"'
|
||||
}')
|
||||
```
|
||||
|
||||
### Pattern 3: Conditional Behavior
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# Behave differently for manual vs automated executions
|
||||
if [ -n "$ATTUNE_RULE" ]; then
|
||||
# Automated execution (from rule)
|
||||
echo "Automated execution via rule: $ATTUNE_RULE" >&2
|
||||
NOTIFICATION_CHANNEL="automated"
|
||||
else
|
||||
# Manual execution
|
||||
echo "Manual execution" >&2
|
||||
NOTIFICATION_CHANNEL="manual"
|
||||
fi
|
||||
|
||||
# Different behavior based on trigger
|
||||
if [ "$ATTUNE_TRIGGER" = "core.webhook" ]; then
|
||||
echo "Processing webhook payload..." >&2
|
||||
elif [ "$ATTUNE_TRIGGER" = "core.intervaltimer" ]; then
|
||||
echo "Processing scheduled task..." >&2
|
||||
fi
|
||||
```
|
||||
|
||||
### Pattern 4: Temporary Files
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# Create execution-specific temp files
|
||||
WORK_DIR="/tmp/attune-exec-${ATTUNE_EXEC_ID}"
|
||||
mkdir -p "$WORK_DIR"
|
||||
|
||||
# Use temp directory
|
||||
echo "Working in: $WORK_DIR" >&2
|
||||
cp input.json "$WORK_DIR/input.json"
|
||||
|
||||
# Process files
|
||||
process_data "$WORK_DIR/input.json" > "$WORK_DIR/output.json"
|
||||
|
||||
# Output result
|
||||
cat "$WORK_DIR/output.json"
|
||||
|
||||
# Cleanup
|
||||
rm -rf "$WORK_DIR"
|
||||
```
|
||||
|
||||
### Pattern 5: Progress Reporting
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
report_progress() {
|
||||
local message="$1"
|
||||
local percent="$2"
|
||||
|
||||
echo "$message" >&2
|
||||
|
||||
# Optional: Report to API (if endpoint exists)
|
||||
curl -s -X PATCH \
|
||||
-H "Authorization: Bearer $ATTUNE_API_TOKEN" \
|
||||
-H "Content-Type: application/json" \
|
||||
"$ATTUNE_API_URL/api/v1/executions/$ATTUNE_EXEC_ID" \
|
||||
-d "{\"progress\": $percent, \"message\": \"$message\"}" \
|
||||
> /dev/null 2>&1 || true
|
||||
}
|
||||
|
||||
report_progress "Starting download" 0
|
||||
# ... download ...
|
||||
report_progress "Processing data" 50
|
||||
# ... process ...
|
||||
report_progress "Uploading results" 90
|
||||
# ... upload ...
|
||||
report_progress "Completed" 100
|
||||
```
|
||||
|
||||
## Security Considerations
|
||||
|
||||
### Token Scope
|
||||
|
||||
The `ATTUNE_API_TOKEN` is scoped to the execution:
|
||||
- ✅ Can read own execution data
|
||||
- ✅ Can create child executions
|
||||
- ✅ Can access secrets owned by execution identity
|
||||
- ❌ Cannot read other executions
|
||||
- ❌ Cannot modify system configuration
|
||||
- ❌ Cannot delete resources
|
||||
|
||||
### Token Lifetime
|
||||
|
||||
- Token is valid for the duration of the execution
|
||||
- Token expires when execution completes
|
||||
- Token is invalidated if execution is cancelled
|
||||
- Do not cache or persist the token
|
||||
|
||||
### Best Practices
|
||||
|
||||
1. **Never log the API token:**
|
||||
```bash
|
||||
# ❌ BAD
|
||||
echo "Token: $ATTUNE_API_TOKEN" >&2
|
||||
|
||||
# ✅ GOOD
|
||||
echo "Using API token for authentication" >&2
|
||||
```
|
||||
|
||||
2. **Validate token presence:**
|
||||
```bash
|
||||
if [ -z "$ATTUNE_API_TOKEN" ]; then
|
||||
echo "ERROR: ATTUNE_API_TOKEN not set" >&2
|
||||
exit 1
|
||||
fi
|
||||
```
|
||||
|
||||
3. **Use HTTPS in production:**
|
||||
```bash
|
||||
# Check API URL uses HTTPS
|
||||
if [[ ! "$ATTUNE_API_URL" =~ ^https:// ]] && [ "$ENVIRONMENT" = "production" ]; then
|
||||
echo "WARNING: API URL should use HTTPS in production" >&2
|
||||
fi
|
||||
```
|
||||
|
||||
## Distinction: Environment Variables vs Parameters
|
||||
|
||||
### Standard Environment Variables
|
||||
- **Purpose:** Execution context and metadata
|
||||
- **Source:** System-provided automatically
|
||||
- **Examples:** `ATTUNE_ACTION`, `ATTUNE_EXEC_ID`, `ATTUNE_API_TOKEN`
|
||||
- **Access:** Standard environment variable access
|
||||
- **Used for:** Logging, API access, execution identity
|
||||
|
||||
### Custom Environment Variables
|
||||
- **Purpose:** Runtime configuration and debug settings
|
||||
- **Source:** User-provided via API/UI (optional)
|
||||
- **Examples:** `DEBUG=true`, `LOG_LEVEL=debug`, `MAX_RETRIES=5`
|
||||
- **Access:** Standard environment variable access
|
||||
- **Used for:** Debug flags, feature toggles, non-sensitive runtime config
|
||||
|
||||
### Action Parameters
|
||||
- **Purpose:** Action-specific input data
|
||||
- **Source:** User-provided via API/UI (required/optional per action)
|
||||
- **Examples:** `{"url": "...", "method": "POST", "data": {...}}`
|
||||
- **Access:** Read from stdin as JSON
|
||||
- **Used for:** Action-specific configuration and data
|
||||
|
||||
**Example:**
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# Standard environment variables - system context (always present)
|
||||
echo "Action: $ATTUNE_ACTION" >&2
|
||||
echo "Execution ID: $ATTUNE_EXEC_ID" >&2
|
||||
|
||||
# Custom environment variables - runtime config (optional)
|
||||
DEBUG="${DEBUG:-false}"
|
||||
LOG_LEVEL="${LOG_LEVEL:-info}"
|
||||
if [ "$DEBUG" = "true" ]; then
|
||||
set -x
|
||||
fi
|
||||
|
||||
# Action parameters - user data (from stdin)
|
||||
INPUT=$(cat)
|
||||
URL=$(echo "$INPUT" | jq -r '.url')
|
||||
METHOD=$(echo "$INPUT" | jq -r '.method // "GET"')
|
||||
|
||||
# Use all three together
|
||||
curl -s -X "$METHOD" \
|
||||
-H "X-Attune-Action: $ATTUNE_ACTION" \
|
||||
-H "X-Attune-Exec-Id: $ATTUNE_EXEC_ID" \
|
||||
-H "X-Debug-Mode: $DEBUG" \
|
||||
"$URL"
|
||||
```
|
||||
|
||||
## Testing Locally
|
||||
|
||||
When testing actions locally, you can simulate these environment variables:
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# test-action.sh - Local testing script
|
||||
|
||||
export ATTUNE_ACTION="core.http_request"
|
||||
export ATTUNE_EXEC_ID="99999"
|
||||
export ATTUNE_API_TOKEN="test-token-local"
|
||||
export ATTUNE_RULE="test.rule"
|
||||
export ATTUNE_TRIGGER="test.trigger"
|
||||
export ATTUNE_API_URL="http://localhost:8080"
|
||||
|
||||
# Simulate custom env vars
|
||||
export DEBUG="true"
|
||||
export LOG_LEVEL="debug"
|
||||
|
||||
echo '{"url": "https://httpbin.org/get"}' | ./http_request.sh
|
||||
```

# Quick Reference: Pack Management API
|
||||
|
||||
**Last Updated:** 2026-02-05
|
||||
|
||||
## Overview
|
||||
|
||||
Four API endpoints for pack installation workflow:
|
||||
1. **Download** - Fetch packs from sources
|
||||
2. **Dependencies** - Analyze requirements
|
||||
3. **Build Envs** - Prepare runtimes (detection mode)
|
||||
4. **Register** - Import to database
|
||||
|
||||
All endpoints require Bearer token authentication.

## Action Wrappers
|
||||
|
||||
Execute via CLI or workflows:
|
||||
|
||||
```bash
|
||||
# Download
|
||||
attune action execute core.download_packs \
|
||||
--param packs='["core"]' \
|
||||
--param destination_dir=/tmp/packs
|
||||
|
||||
# Analyze dependencies
|
||||
attune action execute core.get_pack_dependencies \
|
||||
--param pack_paths='["/tmp/packs/core"]'
|
||||
|
||||
# Build environments

---
|
||||
|
||||
## Complete Workflow Example
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
TOKEN=$(attune auth token)
|
||||
|
||||
# 1. Download
|
||||
DOWNLOAD=$(curl -s -X POST http://localhost:8080/api/v1/packs/download \
|
||||
-H "Authorization: Bearer $TOKEN" \
|

||||
curl -X POST http://localhost:8080/api/v1/packs/dependencies \
|
||||
-H "Authorization: Bearer $TOKEN" \
|
||||
-H "Content-Type: application/json" \
|
||||
-d "{\"pack_paths\":[\"$PACK_PATH\"]}"
|
||||
|
||||
# 3. Build/check environments

|
||||
-d "{\"pack_paths\":[\"$PACK_PATH\"],\"skip_tests\":true}"
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Common Parameters
|
||||
|
||||
### Source Formats (download)
|
||||
- **Registry name:** `"core"`, `"aws"`
|
||||
- **Git URL:** `"https://github.com/org/repo.git"`
|
||||
- **Git shorthand:** `"github:org/repo@tag"`
|
||||
- **Local path:** `"/path/to/pack"`
|
||||
|
||||
### Auth Token
|
||||
```bash
|
||||
# Get token via CLI
|
||||
TOKEN=$(attune auth token)
|
||||
|
||||
# Or login directly
|
||||
LOGIN=$(curl -X POST http://localhost:8080/api/v1/auth/login \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"email":"user@example.com","password":"pass"}')
|
||||
TOKEN=$(echo "$LOGIN" | jq -r '.data.access_token')
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Error Handling
|
||||
|
||||
All endpoints return 200 with per-pack results:
|
||||
|
||||
```json
|
||||
{
|
||||
"data": {
|
||||
"successful_items": [...],
|
||||
"failed_items": [
|
||||
{
|
||||
"pack_ref": "unknown",
|
||||
"error": "pack.yaml not found"
|
||||
}
|
||||
]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Check `success_count` vs `failure_count` in summary.
|
||||
|
||||
---
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Check authentication first** - Verify token works
|
||||
2. **Process downloads** - Check `downloaded_packs` array
|
||||
3. **Validate dependencies** - Ensure `missing_dependencies` is empty
|
||||
4. **Skip tests in dev** - Use `skip_tests: true` for faster iteration
|
||||
5. **Use force carefully** - Only re-register when needed
|
||||
|
||||
---
|
||||
|
||||
## Testing Quick Start
|
||||
|
||||
```bash
|
||||
# 1. Start API
|
||||
make run-api
|
||||
|
||||
# 2. Get token
|
||||
TOKEN=$(curl -s -X POST http://localhost:8080/api/v1/auth/login \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"email":"test@attune.local","password":"TestPass123!"}' \
|
||||
| jq -r '.data.access_token')
|
||||
|
||||
# 3. Test endpoint
|
||||
curl -X POST http://localhost:8080/api/v1/packs/dependencies \
|
||||
-H "Authorization: Bearer $TOKEN" \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"pack_paths":[]}' | jq
|
||||
```

# Quick Reference: Packs Volume Architecture
|
||||
|
||||
## TL;DR
|
||||
|
||||
**Packs are NOT copied into Docker images. They are mounted as volumes.**
|
||||
|
||||
```bash
|
||||
# Build pack binaries (one-time or when updated)
|
||||
./scripts/build-pack-binaries.sh
|
||||
|
||||
# Start services - init-packs copies packs to volume
|
||||
docker compose up -d
|
||||
|
||||
# Update pack files - no image rebuild needed!
|
||||
vim packs/core/actions/my_action.yaml
|
||||
docker compose restart
|
||||
```
|
||||
|
||||
## Architecture Overview
|
||||
|
||||
```
|
||||

```
|
||||
|
||||
## Why Volumes Instead of COPY?
|
||||
|
||||
| Aspect | COPY into Image | Volume Mount |
|
||||
|--------|----------------|--------------|
|
||||
| **Update packs** | Rebuild image (~5 min) | Restart service (~5 sec) |
|
||||
| **Image size** | Larger (+packs) | Smaller (no packs) |
|
||||
| **Development** | Slow iteration | Fast iteration |
|
||||
| **Consistency** | Each service separate | All services share |
|
||||
| **Pack binaries** | Baked into image | Updateable |
|
||||
|
||||
## docker-compose.yaml Configuration
|
||||
|
||||
```yaml
|
||||
volumes:
|
||||
packs_data:
|
||||
driver: local
|
||||
|
||||
services:
|
||||
# Step 1: init-packs runs once to populate packs_data volume
|
||||
init-packs:
|
||||
image: python:3.11-alpine
|
||||
volumes:
|
||||
- ./packs:/source/packs:ro # Host packs (read-only)
|
||||
- packs_data:/opt/attune/packs # Target volume
|
||||
command: ["/bin/sh", "/init-packs.sh"]
|
||||
restart: on-failure
|
||||
|
||||
# Step 2: Services mount packs_data as read-only
|
||||
api:
|
||||
volumes:
|
||||
- packs_data:/opt/attune/packs:ro # Production packs (RO)
|
||||
- ./packs.dev:/opt/attune/packs.dev:rw # Dev packs (RW)
|
||||
depends_on:
|
||||
init-packs:
|
||||
condition: service_completed_successfully
|
||||
|
||||
worker-shell:
|
||||
volumes:
|
||||
- packs_data:/opt/attune/packs:ro # Same volume
|
||||
- ./packs.dev:/opt/attune/packs.dev:rw
|
||||
|
||||
# ... all services follow same pattern
|
||||
```
|
||||
|
||||
## Pack Binaries (Native Code)
|
||||
|
||||
Some packs contain compiled binaries (e.g., sensors written in Rust).
|
||||
|
||||
### Building Pack Binaries
|
||||
|
||||
**Option 1: Use the script (recommended)**
|
||||
```bash
|
||||
./scripts/build-pack-binaries.sh
|
||||
```
|
||||
|
||||
**Option 2: Manual build**
|
||||
```bash
|
||||
# Build in Docker with GLIBC compatibility
|
||||
docker build -f docker/Dockerfile.pack-binaries -t attune-pack-builder .
|
||||
|
||||
# Extract binaries
|
||||
docker create --name pack-tmp attune-pack-builder
|
||||
docker cp pack-tmp:/pack-binaries/. ./packs/
|
||||
docker rm pack-tmp
|
||||
```
|
||||
|
||||
**Option 3: Native build (if GLIBC matches)**
|
||||
```bash
|
||||
cargo build --release --bin attune-core-timer-sensor
|
||||
cp target/release/attune-core-timer-sensor packs/core/sensors/
|
||||
```
|
||||
|
||||
### When to Rebuild Pack Binaries
|
||||
|
||||
- ✅ After `git pull` that updates pack binary source
|
||||
- ✅ After modifying sensor source code (e.g., `crates/core-timer-sensor`)
|
||||
- ✅ When setting up development environment for first time
|
||||
- ❌ NOT needed for YAML/script changes in packs
|
||||
|
||||
## Development Workflow
|
||||
|
||||
### Editing Pack YAML Files
|
||||
|
||||
```bash
|
||||
# 1. Edit pack files
|
||||
vim packs/core/actions/echo.yaml
|
||||
|
||||
# 2. Restart services (no rebuild!)
|
||||
docker compose restart
|
||||
|
||||
# 3. Test changes
|
||||
curl -X POST http://localhost:8080/api/v1/executions \
|
||||
-H "Authorization: Bearer $TOKEN" \
|
||||
-d '{"action_ref": "core.echo", "parameters": {"message": "hello"}}'
|
||||
```
|
||||
|
||||
**Time**: ~5 seconds
|
||||
|
||||
### Editing Pack Scripts (Python/Shell)
|
||||
|
||||
```bash
|
||||
# 1. Edit script
|
||||
vim packs/core/actions/http_request.py
|
||||
|
||||
# 2. Restart services
|
||||
docker compose restart worker-python
|
||||
|
||||
# 3. Test
|
||||
# (run execution)
|
||||
```
|
||||
|
||||
**Time**: ~5 seconds
|
||||
|
||||
### Editing Pack Binaries (Native Sensors)
|
||||
|
||||
```bash
|
||||
# 1. Edit source
|
||||
vim crates/core-timer-sensor/src/main.rs
|
||||
|
||||
# 2. Rebuild binary
|
||||
./scripts/build-pack-binaries.sh
|
||||
|
||||
# 3. Restart services
|
||||
docker compose restart sensor
|
||||
|
||||
# 4. Test
|
||||
# (check sensor registration)
|
||||
```
|
||||
|
||||
**Time**: ~2 minutes (compile + restart)
|
||||
|
||||
## Development Packs (packs.dev)
|
||||
|
||||
For rapid development, use the `packs.dev` directory:
|
||||
|
||||
```bash
|
||||
# Create a dev pack
|
||||
mkdir -p packs.dev/mypack/actions
|
||||
|
||||
# Create action
|
||||
cat > packs.dev/mypack/actions/test.yaml <<EOF
|
||||
name: test
|
||||
description: Test action
|
||||
runner_type: Shell
|
||||
entry_point: echo.sh
|
||||
parameters:
|
||||
message:
|
||||
type: string
|
||||
required: true
|
||||
EOF
|
||||
|
||||
cat > packs.dev/mypack/actions/echo.sh <<'EOF'
|
||||
#!/bin/bash
|
||||
echo "Message: $ATTUNE_MESSAGE"
|
||||
EOF
|
||||
|
||||
chmod +x packs.dev/mypack/actions/echo.sh
|
||||
|
||||
# Restart to pick up changes
|
||||
docker compose restart
|
||||
|
||||
# Test immediately - no rebuild needed!
|
||||
```
|
||||
|
||||
**Benefits of packs.dev**:
|
||||
- ✅ Direct bind mount (changes visible immediately)
|
||||
- ✅ Read-write access (can modify from container)
|
||||
- ✅ No init-packs step needed
|
||||
- ✅ Perfect for iteration
|
||||
|
||||
## Optimized Dockerfiles and Packs
|
||||
|
||||
The optimized Dockerfiles (`docker/Dockerfile.optimized`) do NOT copy packs:
|
||||
|
||||
```dockerfile
|
||||
# ❌ OLD: Packs copied into image
|
||||
COPY packs/ ./packs/
|
||||
|
||||
# ✅ NEW: Only create mount point
|
||||
RUN mkdir -p /opt/attune/packs /opt/attune/logs
|
||||
|
||||
# Packs mounted at runtime from packs_data volume
|
||||
```
|
||||
|
||||
**Result**:
|
||||
- Service images contain only binaries + configs
|
||||
- Packs updated independently
|
||||
- Faster builds (no pack layer invalidation)
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### "Pack not found" errors
|
||||
|
||||
**Symptom**: API returns 404 for pack/action
|
||||
**Cause**: Packs not loaded into volume
|
||||
|
||||
**Fix**:
|
||||
```bash
|
||||
# Check if packs exist in volume
|
||||
docker compose exec api ls -la /opt/attune/packs/
|
||||
|
||||
# If empty, restart init-packs
|
||||
docker compose restart init-packs
|
||||
docker compose logs init-packs
|
||||
```
|
||||
|
||||
### Pack changes not visible
|
||||
|
||||
**Symptom**: Updated pack.yaml but changes not reflected
|
||||
**Cause**: Changes made to host `./packs/` after init-packs ran
|
||||
|
||||
**Fix**:
|
||||
```bash
|
||||
# Option 1: Use packs.dev for development
|
||||
mv packs/mypack packs.dev/mypack
|
||||
docker compose restart
|
||||
|
||||
# Option 2: Recreate packs_data volume
|
||||
docker compose down
|
||||
docker volume rm attune_packs_data
|
||||
docker compose up -d
|
||||
```
|
||||
|
||||
### Pack binary "exec format error"
|
||||
|
||||
**Symptom**: Sensor binary fails with exec format error
|
||||
**Cause**: Binary compiled for wrong architecture or GLIBC version
|
||||
|
||||
**Fix**:
|
||||
```bash
|
||||
# Rebuild with Docker (ensures compatibility)
|
||||
./scripts/build-pack-binaries.sh
|
||||
|
||||
# Restart sensor service
|
||||
docker compose restart sensor
|
||||
```
|
||||
|
||||
### Pack binary "permission denied"
|
||||
|
||||
**Symptom**: Binary exists but can't execute
|
||||
**Cause**: Binary not executable
|
||||
|
||||
**Fix**:
|
||||
```bash
|
||||
chmod +x packs/core/sensors/attune-core-timer-sensor
|
||||
docker compose restart init-packs sensor
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
### DO:
|
||||
- ✅ Use `./scripts/build-pack-binaries.sh` for pack binaries
|
||||
- ✅ Put development packs in `packs.dev/`
|
||||
- ✅ Keep production packs in `packs/`
|
||||
- ✅ Commit pack YAML/scripts to git
|
||||
- ✅ Use `.gitignore` for compiled pack binaries
|
||||
- ✅ Restart services after pack changes
|
||||
- ✅ Use `init-packs` logs to debug loading issues
|
||||
|
||||
### DON'T:
|
||||
- ❌ Don't copy packs into Dockerfiles
|
||||
- ❌ Don't edit packs inside running containers
|
||||
- ❌ Don't commit compiled pack binaries to git
|
||||
- ❌ Don't expect instant updates to `packs/` (need restart)
|
||||
- ❌ Don't rebuild service images for pack changes
|
||||
- ❌ Don't modify packs_data volume directly
|
||||
|
||||
## Migration from Old Dockerfiles
|
||||
|
||||
If your old Dockerfiles copied packs:
|
||||
|
||||
```dockerfile
|
||||
# OLD Dockerfile
|
||||
COPY packs/ ./packs/
|
||||
COPY --from=pack-builder /build/pack-binaries/ ./packs/
|
||||
```
|
||||
|
||||
**Migration steps**:
|
||||
|
||||
1. **Build pack binaries separately**:
|
||||
```bash
|
||||
./scripts/build-pack-binaries.sh
|
||||
```
|
||||
|
||||
2. **Update to optimized Dockerfile**:
|
||||
```yaml
|
||||
# docker-compose.yaml
|
||||
api:
|
||||
build:
|
||||
dockerfile: docker/Dockerfile.optimized
|
||||
```
|
||||
|
||||
3. **Rebuild service images**:
|
||||
```bash
|
||||
docker compose build --no-cache
|
||||
```
|
||||
|
||||
4. **Start services** (init-packs will populate volume):
|
||||
```bash
|
||||
docker compose up -d
|
||||
```
|
||||
|
||||
## Summary
|
||||
|
||||
**Architecture**: Packs → Volume → Services
|
||||
- Host `./packs/` copied to `packs_data` volume by `init-packs`
|
||||
- Services mount `packs_data` as read-only
|
||||
- Dev packs in `packs.dev/` bind-mounted directly
|
||||
|
||||
**Benefits**:
|
||||
- 90% faster pack updates (restart vs rebuild)
|
||||
- Smaller service images
|
||||
- Consistent packs across all services
|
||||
- Clear separation: services = code, packs = content
|
||||
|
||||
**Key Commands**:
|
||||
```bash
|
||||
./scripts/build-pack-binaries.sh # Build native pack binaries
|
||||
docker compose restart # Pick up pack changes
|
||||
docker compose logs init-packs # Debug pack loading
|
||||
```
|
||||
|
||||
**Remember**: Packs are content, not code. Treat them as configuration, not part of the service image.

# Quick Reference: Sensor vs Action Environment Variables
|
||||
|
||||
**Last Updated:** 2026-02-07
|
||||
**Status:** Current Implementation
|
||||
|
||||
## Overview
|
||||
|
||||
Both sensors and actions receive standard environment variables that provide execution context and API access. This document compares the environment variables provided to each to show the parity between the two execution models.
|
||||
|
||||
## Side-by-Side Comparison
|
||||
|
||||
| Purpose | Sensor Variable | Action Variable | Notes |
|
||||
|---------|----------------|-----------------|-------|
|
||||
| **Database ID** | `ATTUNE_SENSOR_ID` | `ATTUNE_EXEC_ID` | Unique identifier in database |
|
||||
| **Reference Name** | `ATTUNE_SENSOR_REF` | `ATTUNE_ACTION` | Human-readable ref (e.g., `core.timer`, `core.http_request`) |
|
||||
| **API Access Token** | `ATTUNE_API_TOKEN` | `ATTUNE_API_TOKEN` | ✅ Same variable name |
|
||||
| **API Base URL** | `ATTUNE_API_URL` | `ATTUNE_API_URL` | ✅ Same variable name |
|
||||
| **Triggering Rule** | N/A | `ATTUNE_RULE` | Only for actions triggered by rules |
|
||||
| **Triggering Event** | N/A | `ATTUNE_TRIGGER` | Only for actions triggered by events |
|
||||
| **Trigger Instances** | `ATTUNE_SENSOR_TRIGGERS` | N/A | Sensor-specific: rules to monitor |
|
||||
| **Message Queue URL** | `ATTUNE_MQ_URL` | N/A | Sensor-specific: for event publishing |
|
||||
| **MQ Exchange** | `ATTUNE_MQ_EXCHANGE` | N/A | Sensor-specific: event destination |
|
||||
| **Log Level** | `ATTUNE_LOG_LEVEL` | N/A | Sensor-specific: runtime logging config |
|
||||
|
||||
## Common Pattern: Identity and Context
|
||||
|
||||
Both sensors and actions follow the same pattern for identity and API access:
|
||||
|
||||
### Identity Variables
|
||||
- **Database ID**: Unique numeric identifier
|
||||
- Sensors: `ATTUNE_SENSOR_ID`
|
||||
- Actions: `ATTUNE_EXEC_ID`
|
||||
- **Reference Name**: Human-readable pack.name format
|
||||
- Sensors: `ATTUNE_SENSOR_REF`
|
||||
- Actions: `ATTUNE_ACTION`
|
||||
|
||||
### API Access Variables (Shared)
|
||||
- `ATTUNE_API_URL` - Base URL for API calls
|
||||
- `ATTUNE_API_TOKEN` - Authentication token
|
||||
|
||||
## Sensor-Specific Variables
|
||||
|
||||
Sensors receive additional variables for their unique responsibilities:
|
||||
|
||||
### Event Publishing
|
||||
- `ATTUNE_MQ_URL` - RabbitMQ connection for publishing events
|
||||
- `ATTUNE_MQ_EXCHANGE` - Exchange name for event routing
|
||||
|
||||
### Monitoring Configuration
|
||||
- `ATTUNE_SENSOR_TRIGGERS` - JSON array of trigger instances to monitor
|
||||
- `ATTUNE_LOG_LEVEL` - Runtime logging verbosity
|
||||
|
||||
### Example Sensor Environment
|
||||
```bash
|
||||
ATTUNE_SENSOR_ID=42
|
||||
ATTUNE_SENSOR_REF=core.interval_timer_sensor
|
||||
ATTUNE_API_URL=http://localhost:8080
|
||||
ATTUNE_API_TOKEN=eyJ0eXAiOiJKV1QiLCJhbGc...
|
||||
ATTUNE_MQ_URL=amqp://localhost:5672
|
||||
ATTUNE_MQ_EXCHANGE=attune.events
|
||||
ATTUNE_SENSOR_TRIGGERS=[{"rule_id":1,"rule_ref":"core.timer_to_echo",...}]
|
||||
ATTUNE_LOG_LEVEL=info
|
||||
```
|
||||
|
||||
## Action-Specific Variables
|
||||
|
||||
Actions receive additional context about their triggering source:
|
||||
|
||||
### Execution Context
|
||||
- `ATTUNE_RULE` - Rule that triggered this execution (if applicable)
|
||||
- `ATTUNE_TRIGGER` - Trigger type that caused the event (if applicable)
|
||||
|
||||
### Example Action Environment (Rule-Triggered)
|
||||
```bash
|
||||
ATTUNE_EXEC_ID=12345
|
||||
ATTUNE_ACTION=core.http_request
|
||||
ATTUNE_API_URL=http://localhost:8080
|
||||
ATTUNE_API_TOKEN=eyJ0eXAiOiJKV1QiLCJhbGc...
|
||||
ATTUNE_RULE=monitoring.disk_space_alert
|
||||
ATTUNE_TRIGGER=core.intervaltimer
|
||||
```
|
||||
|
||||
### Example Action Environment (Manual Execution)
|
||||
```bash
|
||||
ATTUNE_EXEC_ID=12346
|
||||
ATTUNE_ACTION=core.echo
|
||||
ATTUNE_API_URL=http://localhost:8080
|
||||
ATTUNE_API_TOKEN=eyJ0eXAiOiJKV1QiLCJhbGc...
|
||||
# Note: ATTUNE_RULE and ATTUNE_TRIGGER not present for manual executions
|
||||
```
|
||||
|
||||
## Implementation Status
|
||||
|
||||
### Fully Implemented ✅
|
||||
- ✅ Sensor environment variables (all)
|
||||
- ✅ Action identity variables (`ATTUNE_EXEC_ID`, `ATTUNE_ACTION`)
|
||||
- ✅ Action API URL (`ATTUNE_API_URL`)
|
||||
- ✅ Action rule/trigger context (`ATTUNE_RULE`, `ATTUNE_TRIGGER`)
|
||||
|
||||
### Partially Implemented ⚠️
|
||||
- ⚠️ Action API token (`ATTUNE_API_TOKEN`) - Currently set to empty string
|
||||
- Variable is present but token generation not yet implemented
|
||||
- TODO: Implement execution-scoped JWT token generation
|
||||
- See: `work-summary/2026-02-07-env-var-standardization.md`
|
||||
|
||||
## Design Rationale
|
||||
|
||||
### Why Similar Patterns?
|
||||
|
||||
1. **Consistency**: Developers can apply the same mental model to both sensors and actions
|
||||
2. **Tooling**: Shared libraries and utilities can work with both
|
||||
3. **Documentation**: Single set of patterns to learn and document
|
||||
4. **Testing**: Common test patterns for environment setup
|
||||
|
||||
### Why Different Variables?
|
||||
|
||||
1. **Separation of Concerns**: Sensors publish events; actions execute logic
|
||||
2. **Message Queue Access**: Only sensors need direct MQ access for event publishing
|
||||
3. **Execution Context**: Only actions need to know their triggering rule/event
|
||||
4. **Configuration**: Sensors need runtime config (log level, trigger instances)
|
||||
|
||||
## Usage Examples
|
||||
|
||||
### Sensor Using Environment Variables
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# Sensor script example
|
||||
|
||||
echo "Starting sensor: $ATTUNE_SENSOR_REF (ID: $ATTUNE_SENSOR_ID)" >&2
|
||||
|
||||
# Parse trigger instances
|
||||
TRIGGERS=$(echo "$ATTUNE_SENSOR_TRIGGERS" | jq -r '.')
|
||||
|
||||
# Monitor for events and publish to MQ
|
||||
# (Typically sensors use language-specific libraries, not bash)
|
||||
|
||||
# When event occurs, publish to Attune API
|
||||
curl -X POST "$ATTUNE_API_URL/api/v1/events" \
|
||||
-H "Authorization: Bearer $ATTUNE_API_TOKEN" \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"trigger_ref": "core.webhook",
|
||||
"payload": {...}
|
||||
}'
|
||||
```
|
||||
|
||||
### Action Using Environment Variables
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# Action script example
|
||||
|
||||
echo "Executing action: $ATTUNE_ACTION (ID: $ATTUNE_EXEC_ID)" >&2
|
||||
|
||||
if [ -n "$ATTUNE_RULE" ]; then
|
||||
echo "Triggered by rule: $ATTUNE_RULE" >&2
|
||||
echo "Trigger type: $ATTUNE_TRIGGER" >&2
|
||||
else
|
||||
echo "Manual execution (no rule)" >&2
|
||||
fi
|
||||
|
||||
# Read parameters from stdin (NOT environment variables)
|
||||
INPUT=$(cat)
|
||||
MESSAGE=$(echo "$INPUT" | jq -r '.message')
|
||||
|
||||
# Perform action logic
|
||||
echo "Processing: $MESSAGE"
|
||||
|
||||
# Optional: Call API for additional data
|
||||
EXEC_INFO=$(curl -s "$ATTUNE_API_URL/api/v1/executions/$ATTUNE_EXEC_ID" \
|
||||
-H "Authorization: Bearer $ATTUNE_API_TOKEN")
|
||||
|
||||
# Output result to stdout (structured JSON or text)
|
||||
echo '{"status": "success", "message": "'"$MESSAGE"'"}'
|
||||
```
|
||||
|
||||
## Migration Notes
|
||||
|
||||
### Previous Variable Names (Deprecated)
|
||||
|
||||
The following variable names were used in earlier versions and should be migrated:
|
||||
|
||||
| Old Name | New Name | When to Migrate |
|
||||
|----------|----------|----------------|
|
||||
| `ATTUNE_EXECUTION_ID` | `ATTUNE_EXEC_ID` | Immediately |
|
||||
| `ATTUNE_ACTION_REF` | `ATTUNE_ACTION` | Immediately |
|
||||
| `ATTUNE_ACTION_ID` | *(removed)* | Not needed - use `ATTUNE_EXEC_ID` |
|
||||
|
||||
### Migration Script
|
||||
|
||||
If you have existing actions that reference old variable names:
|
||||
|
||||
```bash
|
||||
# Replace in your action scripts
|
||||
sed -i 's/ATTUNE_EXECUTION_ID/ATTUNE_EXEC_ID/g' *.sh
|
||||
sed -i 's/ATTUNE_ACTION_REF/ATTUNE_ACTION/g' *.sh
|
||||
```

# Quick Reference: Worker Lifecycle & Heartbeat Validation
|
||||
|
||||
**Last Updated:** 2026-02-04
|
||||
**Status:** Production Ready
|
||||
|
||||
## Overview
|
||||
|
||||
Workers use graceful shutdown and heartbeat validation to ensure reliable execution scheduling.
|
||||
|
||||
## Worker Lifecycle
|
||||
|
||||
### Startup
|
||||
1. Load configuration
|
||||
2. Connect to database and message queue
|
||||
3. Detect runtime capabilities
|
||||
4. Register in database (status = `Active`)
|
||||
5. Start heartbeat loop
|
||||
6. Start consuming execution messages
|
||||
|
||||
### Normal Operation
|
||||
- **Heartbeat:** Updates `worker.last_heartbeat` every 30 seconds (default)
|
||||
- **Status:** Remains `Active`
|
||||
- **Executions:** Processes messages from worker-specific queue
|
||||
|
||||
### Shutdown (Graceful)
|
||||
1. Receive SIGINT or SIGTERM signal
|
||||
2. Stop heartbeat loop
|
||||
3. Mark worker as `Inactive` in database
|
||||
4. Exit cleanly
|
||||
|
||||
### Shutdown (Crash/Kill)
|
||||
- Worker does not deregister
|
||||
- Status remains `Active` in database
|
||||
- Heartbeat stops updating
|
||||
- **Executor detects as stale after 90 seconds**
|
||||
|
||||
## Heartbeat Validation
|
||||
|
||||
### Configuration
|
||||
```yaml
|
||||
worker:
|
||||
heartbeat_interval: 30 # seconds (default)
|
||||
```
|
||||
|
||||
### Staleness Threshold
|
||||
- **Formula:** `heartbeat_interval * 3 = 90 seconds`
|
||||
- **Rationale:** Allows 2 missed heartbeats + buffer
|
||||
- **Detection:** Executor checks on every scheduling attempt
|
||||
|
||||
### Worker States
|
||||
|
||||
| Last Heartbeat Age | Status | Schedulable |
|
||||
|-------------------|--------|-------------|
|
||||
| < 90 seconds | Fresh | ✅ Yes |
|
||||
| ≥ 90 seconds | Stale | ❌ No |
|
||||
| None/NULL | Stale | ❌ No |

||||

||||

|
||||
|
||||
## Signal Handling
|
||||
|
||||
### Supported Signals
|
||||
- **SIGINT** (Ctrl+C) - Graceful shutdown
|
||||
- **SIGTERM** (docker stop, k8s termination) - Graceful shutdown
|
||||
- **SIGKILL** (force kill) - No cleanup possible
|
||||
|
||||
### Docker Example
|
||||
```bash
|
||||
# Graceful shutdown (10s grace period)
|
||||
docker compose stop worker-shell
|
||||
|
||||
# Force kill (immediate)
|
||||
docker compose kill worker-shell
|
||||
```
|
||||
|
||||
### Kubernetes Example
|
||||
```yaml
|
||||
spec:
|
||||
terminationGracePeriodSeconds: 30 # Time for graceful shutdown
|
||||
```
|
||||
|
||||
## Monitoring & Debugging
|
||||
|
||||
### Check Worker Status
|
||||
```sql
|
||||
SELECT id, name, status, last_heartbeat,
|
||||
EXTRACT(EPOCH FROM (NOW() - last_heartbeat)) as seconds_ago
|
||||
FROM worker
|
||||
WHERE worker_role = 'action'
|
||||
ORDER BY last_heartbeat DESC;
|
||||
```
|
||||
|
||||
### Identify Stale Workers
|
||||
```sql
|
||||
SELECT id, name, status,
|
||||
EXTRACT(EPOCH FROM (NOW() - last_heartbeat)) as seconds_ago
|
||||
FROM worker
|
||||
WHERE worker_role = 'action'
|
||||
AND status = 'active'
|
||||
AND (last_heartbeat IS NULL OR last_heartbeat < NOW() - INTERVAL '90 seconds');
|
||||
```
|
||||
|
||||
### View Worker Logs
|
||||
```bash
|
||||
# Docker Compose
|
||||
docker compose logs -f worker-shell
|
||||
|
||||
# Look for:
|
||||
# - "Worker registered with ID: X"
|
||||
# - "Heartbeat sent successfully" (debug level)
|
||||
# - "Received SIGTERM signal"
|
||||
# - "Deregistering worker ID: X"
|
||||
```
|
||||
|
||||
### View Executor Logs
|
||||
```bash
|
||||
docker compose logs -f executor
|
||||
|
||||
# Look for:
|
||||
# - "Worker X heartbeat is stale: last seen N seconds ago"
|
||||
# - "No workers with fresh heartbeats available"
|
||||
```
|
||||
|
||||
## Common Issues
|
||||
|
||||
### Issue: "No workers with fresh heartbeats available"
|
||||
|
||||
**Causes:**
|
||||
1. All workers crashed/terminated
|
||||
2. Workers paused/frozen
|
||||
3. Network partition between workers and database
|
||||
4. Database connection issues
|
||||
|
||||
**Solutions:**
|
||||
1. Check if workers are running: `docker compose ps`
|
||||
2. Restart workers: `docker compose restart worker-shell`
|
||||
3. Check worker logs for errors
|
||||
4. Verify database connectivity
|
||||
|
||||
### Issue: Worker not deregistering on shutdown
|
||||
|
||||
**Causes:**
|
||||
1. SIGKILL used instead of SIGTERM
|
||||
2. Grace period too short
|
||||
3. Database connection lost before deregister
|
||||
|
||||
**Solutions:**
|
||||
1. Use `docker compose stop` not `docker compose kill`
|
||||
2. Increase grace period: `docker compose down -t 30`
|
||||
3. Check network connectivity
|
||||
|
||||
### Issue: Worker stuck in Active status after crash
|
||||
|
||||
**Behavior:** Normal - executor will detect as stale after 90s
|
||||
|
||||
**Manual Cleanup (if needed):**
|
||||
```sql
|
||||
UPDATE worker
|
||||
SET status = 'inactive'
|
||||
WHERE last_heartbeat < NOW() - INTERVAL '5 minutes';
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
### Test Graceful Shutdown
|
||||
```bash
|
||||
# Start worker
|
||||
docker compose up -d worker-shell
|
||||
|
||||
# Wait for registration
|
||||
sleep 5
|
||||
|
||||
# Check status (should be 'active')
|
||||
docker compose exec postgres psql -U attune -c \
|
||||
"SELECT name, status FROM worker WHERE name LIKE 'worker-shell%';"
|
||||
|
||||
# Graceful shutdown
|
||||
docker compose stop worker-shell
|
||||
|
||||
# Check status (should be 'inactive')
|
||||
docker compose exec postgres psql -U attune -c \
|
||||
"SELECT name, status FROM worker WHERE name LIKE 'worker-shell%';"
|
||||
```
|
||||
|
||||
### Test Heartbeat Validation
|
||||
```bash
|
||||
# Pause worker (simulate freeze)
|
||||
docker compose pause worker-shell
|
||||
|
||||
# Wait for staleness (90+ seconds)
|
||||
sleep 100
|
||||
|
||||
# Try to schedule execution (should fail)
|
||||
# Use API or CLI to trigger execution
|
||||
attune execution create --action core.echo --param message="test"
|
||||
|
||||
# Should see: "No workers with fresh heartbeats available"
|
||||
```
|
||||
|
||||
## Configuration Reference
|
||||
|
||||
### Worker Config
|
||||
```yaml
|
||||
worker:
|
||||
name: "worker-01"
|
||||
heartbeat_interval: 30 # Heartbeat update frequency (seconds)
|
||||
max_concurrent_tasks: 10 # Concurrent execution limit
|
||||
task_timeout: 300 # Per-task timeout (seconds)
|
||||
```
|
||||
|
||||
### Relevant Constants
|
||||
```rust
|
||||
// crates/executor/src/scheduler.rs
|
||||
const DEFAULT_HEARTBEAT_INTERVAL: u64 = 30;
|
||||
const HEARTBEAT_STALENESS_MULTIPLIER: u64 = 3;
|
||||
// Max age = 90 seconds
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Use Graceful Shutdown:** Always use SIGTERM, not SIGKILL
|
||||
2. **Monitor Heartbeats:** Alert when workers go stale
|
||||
3. **Set Grace Periods:** Allow 10-30s for worker shutdown in production
|
||||
4. **Health Checks:** Implement liveness probes in Kubernetes
|
||||
5. **Auto-Restart:** Configure restart policies for crashed workers

# TODO: Execution-Scoped API Token Generation
|
||||
|
||||
**Priority:** High
|
||||
**Status:** Not Started
|
||||
**Related Work:** `work-summary/2026-02-07-env-var-standardization.md`
|
||||
**Blocked By:** None
|
||||
**Blocking:** Full API access from action executions
|
||||
|
||||
## Overview
|
||||
|
||||
Actions currently receive an empty `ATTUNE_API_TOKEN` environment variable. This TODO tracks the implementation of execution-scoped JWT token generation to enable actions to authenticate with the Attune API.
|
||||
|
||||
## Background
|
||||
|
||||
As of 2026-02-07, the environment variable standardization work updated the worker to provide standard environment variables to actions, including `ATTUNE_API_TOKEN`. However, token generation is not yet implemented - the variable is set to an empty string as a placeholder.
|
||||
|
||||
## Requirements
|
||||
|
||||
### Functional Requirements
|
||||
|
||||
1. **Token Generation**: Generate JWT tokens scoped to specific executions
|
||||
2. **Token Claims**: Include execution-specific claims and permissions
|
||||
3. **Token Lifecycle**: Tokens expire with execution or after timeout
|
||||
4. **Security**: Tokens cannot access other executions or system resources
|
||||
5. **Integration**: Seamlessly integrate into existing execution flow
|
||||
|
||||
### Non-Functional Requirements
|
||||
|
||||
1. **Performance**: Token generation should not significantly delay execution startup
|
||||
2. **Security**: Follow JWT best practices and secure token scoping
|
||||
3. **Consistency**: Match patterns from sensor token generation
|
||||
4. **Testability**: Unit and integration tests for token generation and validation
|
||||
|
||||
## Design
|
||||
|
||||
### Token Claims Structure
|
||||
|
||||
```json
|
||||
{
|
||||
"sub": "execution:12345",
|
||||
"identity_id": 42,
|
||||
"execution_id": 12345,
|
||||
"scopes": [
|
||||
"execution:read:self",
|
||||
"execution:create:child",
|
||||
"secrets:read:owned"
|
||||
],
|
||||
"iat": 1738934400,
|
||||
"exp": 1738938000,
|
||||
"nbf": 1738934400
|
||||
}
|
||||
```
|
||||
|
||||
### Token Scopes
|
||||
|
||||
| Scope | Description | Use Case |
|
||||
|-------|-------------|----------|
|
||||
| `execution:read:self` | Read own execution data | Query execution status, retrieve parameters |
|
||||
| `execution:create:child` | Create child executions | Workflow orchestration, sub-tasks |
|
||||
| `secrets:read:owned` | Access secrets owned by execution identity | Retrieve API keys, credentials |
|
||||
|
||||
### Token Expiration

||||
- **Default Expiration**: Execution timeout (from action metadata) or 5 minutes (300 seconds)
|
||||
- **Maximum Expiration**: 1 hour (configurable)
|
||||
- **Auto-Invalidation**: Token marked invalid when execution completes/fails/cancels
|
||||
|
||||
### Token Generation Flow
|
||||
|
||||
1. Executor receives execution request from queue
|
||||
2. Executor loads action metadata (includes timeout)
|
||||
3. Executor generates execution-scoped JWT token:
|
||||
- Subject: `execution:{id}`
|
||||
- Claims: execution ID, identity ID, scopes
|
||||
- Expiration: now + timeout or max lifetime
|
||||
4. Token added to environment variables (`ATTUNE_API_TOKEN`)
|
||||
5. Action script uses token for API authentication
|
||||
|
||||
## Implementation Tasks
|
||||
|
||||
### Phase 1: Token Generation Service
|
||||
|
||||
- [ ] Create `TokenService` or add to existing auth service
|
||||
- [ ] Implement `generate_execution_token(execution_id, identity_id, timeout)` method
|
||||
- [ ] Use same JWT signing key as API service
|
||||
- [ ] Add token generation to `ActionExecutor::prepare_execution_context()`
|
||||
- [ ] Replace empty string with generated token
|
||||
|
||||
**Files to Modify:**
|
||||
- `crates/common/src/auth.rs` (or create new token module)
|
||||
- `crates/worker/src/executor.rs` (line ~220)
|
||||
|
||||
**Estimated Effort:** 4-6 hours
|
||||
|
||||
### Phase 2: Token Validation
|
||||
|
||||
- [ ] Update API auth middleware to recognize execution-scoped tokens
|
||||
- [ ] Validate token scopes against requested resources
|
||||
- [ ] Ensure execution tokens cannot access other executions
|
||||
- [ ] Add scope checking to protected endpoints
|
||||
|
||||
**Files to Modify:**
|
||||
- `crates/api/src/auth/middleware.rs`
|
||||
- `crates/api/src/auth/jwt.rs`
|
||||
|
||||
**Estimated Effort:** 3-4 hours
|
||||
|
||||
### Phase 3: Token Lifecycle Management
|
||||
|
||||
- [ ] Track active execution tokens in memory or cache
|
||||
- [ ] Invalidate tokens when execution completes
|
||||
- [ ] Handle token refresh (if needed for long-running actions)
|
||||
- [ ] Add cleanup for orphaned tokens
|
||||
|
||||
**Files to Modify:**
|
||||
- `crates/worker/src/executor.rs`
|
||||
- Consider adding token registry/cache
|
||||
|
||||
**Estimated Effort:** 2-3 hours
|
||||
|
||||
### Phase 4: Testing
|
||||
|
||||
- [ ] Unit tests for token generation
|
||||
- [ ] Unit tests for token validation and scope checking
|
||||
- [ ] Integration test: action calls API with generated token
|
||||
- [ ] Integration test: verify token cannot access other executions
|
||||
- [ ] Integration test: verify token expires appropriately
|
||||
- [ ] Test child execution creation with token
|
||||
|
||||
**Files to Create:**
|
||||
- `crates/worker/tests/token_generation_tests.rs`
|
||||
- `crates/api/tests/execution_token_auth_tests.rs`
|
||||
|
||||
**Estimated Effort:** 4-5 hours
|
||||
|
||||
### Phase 5: Documentation
|
||||
|
||||
- [ ] Document token generation in worker architecture docs
|
||||
- [ ] Update QUICKREF-execution-environment.md with token details
|
||||
- [ ] Add security considerations to documentation
|
||||
- [ ] Provide examples of actions using API with token
|
||||
- [ ] Document troubleshooting for token-related issues
|
||||
|
||||
**Files to Update:**
|
||||
- `docs/QUICKREF-execution-environment.md`
|
||||
- `docs/architecture/worker-service.md`
|
||||
- `docs/authentication/authentication.md`
|
||||
- `packs/core/actions/README.md` (add API usage examples)
|
||||
|
||||
**Estimated Effort:** 2-3 hours
|
||||
|
||||
## Technical Details
|
||||
|
||||
### JWT Signing
|
||||
|
||||
Use the same JWT secret as the API service:
|
||||
|
||||
```rust
|
||||
use jsonwebtoken::{encode, EncodingKey, Header};
|
||||
|
||||
let token = encode(
|
||||
&Header::default(),
|
||||
&claims,
|
||||
&EncodingKey::from_secret(jwt_secret.as_bytes()),
|
||||
)?;
|
||||
```
|
||||
|
||||
### Token Structure Reference
|
||||
|
||||
Look at sensor token generation in `crates/sensor/src/api_client.rs` for patterns:
|
||||
- Similar claims structure
|
||||
- Similar expiration handling
|
||||
- Can reuse token generation utilities
|
||||
|
||||
### Middleware Integration
|
||||
|
||||
Update `RequireAuth` extractor to handle execution-scoped tokens:
|
||||
|
||||
```rust
|
||||
// Pseudo-code
|
||||
match token_subject_type {
|
||||
"user" => validate_user_token(token),
|
||||
"service_account" => validate_service_token(token),
|
||||
"execution" => validate_execution_token(token, execution_id_from_route),
|
||||
}
|
||||
```
|
||||
|
||||
### Scope Validation
|
||||
|
||||
Add scope checking helper:
|
||||
|
||||
```rust
|
||||
fn require_scope(token: &Token, required_scope: &str) -> Result<()> {
|
||||
if token.scopes.contains(&required_scope.to_string()) {
|
||||
Ok(())
|
||||
} else {
|
||||
Err(Error::Forbidden("Insufficient scope"))
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Security Considerations
|
||||
|
||||
### Token Scoping
|
||||
|
||||
1. **Execution Isolation**: Token must only access its own execution
|
||||
2. **No System Access**: Cannot modify system configuration
|
||||
3. **Limited Secrets**: Only secrets owned by execution identity
|
||||
4. **Time-Bounded**: Expires with execution or timeout
|
||||
|
||||
### Attack Vectors to Prevent
|
||||
|
||||
1. **Token Reuse**: Expired tokens must be rejected
|
||||
2. **Cross-Execution Access**: Token for execution A cannot access execution B
|
||||
3. **Privilege Escalation**: Cannot use token to gain admin access
|
||||
4. **Token Leakage**: Never log full token value
|
||||
|
||||
### Validation Checklist
|
||||
|
||||
- [ ] Token signature verified
|
||||
- [ ] Token not expired
|
||||
- [ ] Execution ID matches token claims
|
||||
- [ ] Required scopes present in token
|
||||
- [ ] Identity owns requested resources
|
||||
|
||||
## Testing Strategy
|
||||
|
||||
### Unit Tests
|
||||
|
||||
```rust
|
||||
#[test]
|
||||
fn test_generate_execution_token() {
|
||||
let token = generate_execution_token(12345, 42, 300).unwrap();
|
||||
let claims = decode_token(&token).unwrap();
|
||||
|
||||
assert_eq!(claims.execution_id, 12345);
|
||||
assert_eq!(claims.identity_id, 42);
|
||||
assert!(claims.scopes.contains(&"execution:read:self".to_string()));
|
||||
}
|
||||
|
||||
#[test]
|
||||
fn test_token_cannot_access_other_execution() {
|
||||
let token = generate_execution_token(12345, 42, 300).unwrap();
|
||||
|
||||
// Try to access execution 99999 with token for execution 12345
|
||||
let result = api_client.get_execution(99999, &token).await;
|
||||
assert!(result.is_err());
|
||||
}
|
||||
```
|
||||
|
||||
### Integration Tests
|
||||
|
||||
1. **Happy Path**: Action successfully calls API with token
|
||||
2. **Scope Enforcement**: Action cannot perform unauthorized operations
|
||||
3. **Token Expiration**: Expired token is rejected
|
||||
4. **Child Execution**: Action can create child execution with token
|
||||
|
||||
## Dependencies
|
||||
|
||||
### Required Access
|
||||
|
||||
- JWT secret (same as API service)
|
||||
- Access to execution data (for claims)
|
||||
- Access to identity data (for ownership checks)
|
||||
|
||||
### Configuration
|
||||
|
||||
Add to worker config (or use existing values):
|
||||
|
||||
```yaml
|
||||
security:
|
||||
jwt_secret: "..." # Shared with API
|
||||
execution_token_max_lifetime: 3600 # 1 hour
|
||||
```
|
||||
|
||||
## Success Criteria
|
||||
|
||||
1. ✅ Actions receive valid JWT token in `ATTUNE_API_TOKEN`
|
||||
2. ✅ Actions can authenticate with API using token
|
||||
3. ✅ Token scopes are enforced correctly
|
||||
4. ✅ Tokens cannot access other executions
|
||||
5. ✅ Tokens expire appropriately
|
||||
6. ✅ All tests pass
|
||||
7. ✅ Documentation is complete and accurate

# Parameter Delivery Quick Reference
|
||||
|
||||
**Quick guide for choosing and implementing secure parameter passing in actions**
|
||||
|
||||
---
|
||||
|
||||
## TL;DR - Security First
|
||||
|
||||
**DEFAULT**: `stdin` + `json` (secure by default as of 2025-02-05)
|
||||
|
||||
**KEY DESIGN**: Parameters and environment variables are separate!
|
||||
- **Parameters** = Action data (always secure: stdin or file)
|
||||
- **Environment Variables** = Execution context (separate: `execution.env_vars`)
|
||||
|
||||
```yaml
|
||||
# ✅ DEFAULT (no need to specify) - secure for all actions
|
||||
# parameter_delivery: stdin
|
||||
# parameter_format: json
|
||||
|
||||
# For large payloads only:
|
||||
parameter_delivery: file
|
||||
parameter_format: yaml
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Quick Decision Matrix
|
||||
|
||||
| Your Action Has... | Use This |
|
||||
|--------------------|----------|
|
||||
| 🔑 API keys, passwords, tokens | Default (`stdin` + `json`) |
|
||||
| 📦 Large config files (>1MB) | `file` + `yaml` |
|
||||
| 🐚 Shell scripts | Default (`stdin` + `json` or `dotenv`) |
|
||||
| 🐍 Python/Node.js actions | Default (`stdin` + `json`) |
|
||||
| 📝 Most actions | Default (`stdin` + `json`) |
|
||||
|
||||
---
|
||||
|
||||
## Two Delivery Methods
|
||||
|
||||
### 1. Standard Input (`stdin`)
|
||||
|
||||
**Security**: ✅ HIGH - Not in process list
|
||||
**When**: Credentials, API keys, structured data (DEFAULT)
|
||||
|
||||
```yaml
|
||||
# This is the DEFAULT (no need to specify)
|
||||
# parameter_delivery: stdin
|
||||
# parameter_format: json
|
||||
```
|
||||
|
||||
```python
|
||||
# Read from stdin
|
||||
import sys, json
|
||||
content = sys.stdin.read()
|
||||
params_str = content.split('---ATTUNE_PARAMS_END---')[0]
|
||||
params = json.loads(params_str)
|
||||
api_key = params['api_key'] # Secure!
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 2. Temporary File (`file`)
|
||||
|
||||
**Security**: ✅ HIGH - Restrictive permissions (0400)
|
||||
**When**: Large payloads, complex configs
|
||||
|
||||
```yaml
|
||||
# Explicitly use file for large payloads
|
||||
parameter_delivery: file
|
||||
parameter_format: yaml
|
||||
```
|
||||
|
||||
```python
|
||||
# Read from file
|
||||
import os, yaml
|
||||
param_file = os.environ['ATTUNE_PARAMETER_FILE']
|
||||
with open(param_file) as f:
|
||||
params = yaml.safe_load(f)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Format Options
|
||||
|
||||
| Format | Best For | Example |
|
||||
|--------|----------|---------|
|
||||
| `json` (default) | Python/Node.js, structured data | `{"key": "value"}` |
|
||||
| `dotenv` | Simple key-value when needed | `KEY='value'` |
|
||||
| `yaml` | Human-readable configs | `key: value` |
|
||||
|
||||

|
||||
|
||||
## Copy-Paste Templates
|
||||
|
||||
### Python Action (Secure with Stdin/JSON)
|
||||
|
||||
```yaml
|
||||
# action.yaml
|
||||
name: my_action
|
||||
ref: mypack.my_action
|
||||
runner_type: python
|
||||
entry_point: my_action.py
|
||||
parameter_delivery: stdin
|
||||
parameter_format: json
|
||||
|
||||
parameters:
|
||||
type: object
|
||||
properties:
|
||||
api_key:
|
||||
type: string
|
||||
secret: true
|
||||
```
|
||||
|
||||
```python
|
||||
#!/usr/bin/env python3
|
||||
# my_action.py
|
||||
import sys
|
||||
import json
|
||||
|
||||
def read_params():
|
||||
content = sys.stdin.read()
|
||||
parts = content.split('---ATTUNE_PARAMS_END---')
|
||||
params = json.loads(parts[0].strip()) if parts[0].strip() else {}
|
||||
secrets = json.loads(parts[1].strip()) if len(parts) > 1 and parts[1].strip() else {}
|
||||
return {**params, **secrets}
|
||||
|
||||
params = read_params()
|
||||
api_key = params['api_key']
|
||||
# Use api_key securely...
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Shell Action (Secure with Stdin/JSON)
|
||||
|
||||
```yaml
|
||||
# action.yaml
|
||||
name: my_script
|
||||
ref: mypack.my_script
|
||||
runner_type: shell
|
||||
entry_point: my_script.sh
|
||||
parameter_delivery: stdin
|
||||
parameter_format: json
|
||||
```
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# my_script.sh
|
||||
set -e
|
||||
|
||||
# Read params from stdin (requires jq)
|
||||
read -r PARAMS_JSON
|
||||
API_KEY=$(echo "$PARAMS_JSON" | jq -r '.api_key')
|
||||
|
||||
# Use API_KEY securely...
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Shell Action (Using Stdin with Dotenv)
|
||||
|
||||
```yaml
|
||||
name: simple_script
|
||||
ref: mypack.simple_script
|
||||
runner_type: shell
|
||||
entry_point: simple.sh
|
||||
# Can use dotenv format with stdin for simple shell scripts
|
||||
parameter_delivery: stdin
|
||||
parameter_format: dotenv
|
||||
```
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# simple.sh
|
||||
# Read dotenv from stdin
|
||||
eval "$(cat)"
|
||||
echo "$MESSAGE"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Environment Variables
|
||||
|
||||
**System Variables** (always set):
|
||||
- `ATTUNE_EXECUTION_ID` - Execution ID
|
||||
- `ATTUNE_ACTION_REF` - Action reference
|
||||
- `ATTUNE_PARAMETER_DELIVERY` - Method used (stdin/file, default: stdin)
|
||||
- `ATTUNE_PARAMETER_FORMAT` - Format used (json/dotenv/yaml, default: json)
|
||||
- `ATTUNE_PARAMETER_FILE` - Path to temp file (file delivery only)
|
||||
|
||||
**Custom Variables** (from `execution.env_vars`):
|
||||
- Set any custom environment variables via `execution.env_vars` when creating execution
|
||||
- These are separate from parameters
|
||||
- Use for execution context, configuration, non-sensitive metadata
|
||||
|
||||
---
|
||||
|
||||
## Common Patterns
|
||||
|
||||
### Detect Delivery Method
|
||||
|
||||
```python
|
||||
import os
|
||||
|
||||
delivery = os.environ.get('ATTUNE_PARAMETER_DELIVERY', 'env')
|
||||
if delivery == 'stdin':
|
||||
params = read_from_stdin()
|
||||
elif delivery == 'file':
|
||||
params = read_from_file()
|
||||
else:
|
||||
params = read_from_env()
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Mark Sensitive Parameters
|
||||
|
||||
```yaml
|
||||
parameters:
|
||||
type: object
|
||||
properties:
|
||||
api_key:
|
||||
type: string
|
||||
secret: true # Mark as sensitive
|
||||
password:
|
||||
type: string
|
||||
secret: true
|
||||
public_url:
|
||||
type: string # Not marked - not sensitive
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Validate Required Parameters
|
||||
|
||||
```python
|
||||
params = read_params()
|
||||
if not params.get('api_key'):
|
||||
print(json.dumps({"error": "api_key required"}))
|
||||
sys.exit(1)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Security Checklist
|
||||
|
||||
- [ ] Identified all sensitive parameters
|
||||
- [ ] Marked sensitive params with `secret: true`
|
||||
- [ ] Set `parameter_delivery: stdin` or `file` (not `env`)
|
||||
- [ ] Set appropriate `parameter_format`
|
||||
- [ ] Updated action script to read from stdin/file
|
||||
- [ ] Tested that secrets don't appear in `ps aux`
|
||||
- [ ] Don't log sensitive parameters
|
||||
- [ ] Handle missing parameters gracefully
|
||||
|
||||
---
|
||||
|
||||
## Testing
|
||||
|
||||
```bash
|
||||
# Run action and check process list
|
||||
./attune execution start mypack.my_action --params '{"api_key":"secret123"}' &
|
||||
|
||||
# In another terminal
|
||||
ps aux | grep attune-worker
|
||||
# Should NOT see "secret123" in output!
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Key Design Change (2025-02-05)
|
||||
|
||||
**Parameters and Environment Variables Are Separate**
|
||||
|
||||
**Parameters** (always secure):
|
||||
- Passed via `stdin` (default) or `file` (large payloads)
|
||||
- Never passed as environment variables
|
||||
- Read from stdin or parameter file
|
||||
|
||||
```python
|
||||
# Read parameters from stdin
|
||||
import sys, json
|
||||
content = sys.stdin.read()
|
||||
params = json.loads(content.split('---ATTUNE_PARAMS_END---')[0])
|
||||
api_key = params['api_key'] # Secure!
|
||||
```
|
||||
|
||||
**Environment Variables** (execution context):
|
||||
- Set via `execution.env_vars` when creating execution
|
||||
- Separate from parameters
|
||||
- Read from environment
|
||||
|
||||
```python
|
||||
# Read environment variables (context, not parameters)
|
||||
import os
|
||||
log_level = os.environ.get('LOG_LEVEL', 'info')
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Don't Do This
|
||||
|
||||
```python
|
||||
# ❌ Don't log sensitive parameters
|
||||
logger.debug(f"Params: {params}") # May contain secrets!
|
||||
|
||||
# ❌ Don't confuse parameters with env vars
|
||||
# Parameters come from stdin/file, not environment
|
||||
|
||||
# ❌ Don't forget to mark secrets
|
||||
# api_key:
|
||||
# type: string
|
||||
# # Missing: secret: true
|
||||
|
||||
# ❌ Don't put sensitive data in execution.env_vars
|
||||
# Use parameters for sensitive data, env_vars for context
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Do This Instead
|
||||
|
||||
```python
|
||||
# ✅ Log only non-sensitive data
|
||||
logger.info(f"Calling endpoint: {params['endpoint']}")
|
||||
|
||||
# ✅ Use stdin for parameters (the default!)
|
||||
# parameter_delivery: stdin # No need to specify
|
||||
|
||||
# ✅ Mark all secrets
|
||||
# api_key:
|
||||
# type: string
|
||||
# secret: true
|
||||
|
||||
# ✅ Use env_vars for execution context
|
||||
# Set when creating execution:
|
||||
# {"env_vars": {"LOG_LEVEL": "debug"}}
|
||||
```

|
||||
## Summary
|
||||
|
||||
1. **Default is `stdin` + `json` - secure by default! 🎉**
|
||||
2. **Parameters and environment variables are separate concepts**
|
||||
3. **Parameters are always secure (stdin or file, never env)**
|
||||
4. **Mark sensitive parameters with `secret: true`**
|
||||
5. **Use `execution.env_vars` for execution context, not parameters**
|
||||
6. **Test that secrets aren't in process list**
|
||||
|
||||
**Remember**: Parameters are secure by design - they're never in environment variables! 🔒

# Action Parameter Delivery
|
||||
|
||||
This directory contains documentation for Attune's secure parameter passing system for actions.
|
||||
|
||||
## Quick Links
|
||||
|
||||
- **[Parameter Delivery Guide](./parameter-delivery.md)** - Complete guide to parameter delivery methods, formats, and best practices (568 lines)
|
||||
- **[Quick Reference](./QUICKREF-parameter-delivery.md)** - Quick decision matrix and copy-paste templates (365 lines)
|
||||
|
||||
## Overview
|
||||
|
||||
Attune provides three methods for delivering parameters to actions, with **stdin + JSON as the secure default** (as of 2025-02-05):
|
||||
|
||||
### Delivery Methods
|
||||
|
||||
| Method | Security | Use Case |
|
||||
|--------|----------|----------|
|
||||
| **stdin** (default) | ✅ High | Credentials, structured data, most actions |
|
||||
| **env** (explicit) | ⚠️ Low | Simple non-sensitive shell scripts only |
|
||||
| **file** | ✅ High | Large payloads, complex configurations |
|
||||
|
||||
### Serialization Formats
|
||||
|
||||
| Format | Best For | Example |
|
||||
|--------|----------|---------|
|
||||
| **json** (default) | Python/Node.js, structured data | `{"key": "value"}` |
|
||||
| **dotenv** | Shell scripts, simple key-value | `KEY='value'` |
|
||||
| **yaml** | Human-readable configs | `key: value` |
|
||||
|
||||
## Security Warning
|
||||
|
||||
⚠️ **Environment variables are visible in process listings** (`ps aux`, `/proc/<pid>/environ`)
|
||||
|
||||
**Never use `env` delivery for sensitive parameters** like passwords, API keys, or tokens.
|
||||
|
||||
## Quick Start
|
||||
|
||||
### Secure Action (Default - No Configuration Needed)
|
||||
|
||||
```yaml
|
||||
# action.yaml
|
||||
name: my_action
|
||||
ref: mypack.my_action
|
||||
runner_type: python
|
||||
entry_point: my_action.py
|
||||
# Uses default stdin + json (no need to specify)
|
||||
|
||||
parameters:
|
||||
type: object
|
||||
properties:
|
||||
api_key:
|
||||
type: string
|
||||
secret: true
|
||||
```
|
||||
|
||||
```python
|
||||
# my_action.py
|
||||
import sys, json
|
||||
|
||||
# Read from stdin (the default)
|
||||
content = sys.stdin.read()
|
||||
params = json.loads(content.split('---ATTUNE_PARAMS_END---')[0])
|
||||
api_key = params['api_key'] # Secure - not in process list!
|
||||
```
|
||||
|
||||
### Simple Shell Script (Non-Sensitive - Explicit env)
|
||||
|
||||
```yaml
|
||||
# action.yaml
|
||||
name: simple_script
|
||||
ref: mypack.simple_script
|
||||
runner_type: shell
|
||||
entry_point: simple.sh
|
||||
# Explicitly use env for non-sensitive data
|
||||
parameter_delivery: env
|
||||
parameter_format: dotenv
|
||||
```
|
||||
|
||||
```bash
|
||||
# simple.sh
|
||||
MESSAGE="${ATTUNE_ACTION_MESSAGE:-Hello}"
|
||||
echo "$MESSAGE"
|
||||
```
|
||||
|
||||
## Key Features
|
||||
|
||||
- ✅ **Secure by default** - stdin prevents process listing exposure
|
||||
- ✅ **Type preservation** - JSON format maintains data types
|
||||
- ✅ **Automatic cleanup** - Temporary files auto-deleted
|
||||
- ✅ **Flexible formats** - Choose JSON, YAML, or dotenv
|
||||
- ✅ **Explicit opt-in** - Only use env when you really need it
|
||||
|
||||
## Environment Variables
|
||||
|
||||
All actions receive these metadata variables:
|
||||
|
||||
- `ATTUNE_PARAMETER_DELIVERY` - Method used (stdin/env/file)
|
||||
- `ATTUNE_PARAMETER_FORMAT` - Format used (json/dotenv/yaml)
|
||||
- `ATTUNE_PARAMETER_FILE` - File path (file delivery only)
|
||||
- `ATTUNE_ACTION_<KEY>` - Individual parameters (env delivery only)
|
||||
|
||||
## Breaking Change Notice
|
||||
|
||||
**As of 2025-02-05**, the default parameter delivery changed from `env` to `stdin` for security.
|
||||
|
||||
Actions that need environment variable delivery must **explicitly opt-in** by setting:
|
||||
|
||||
```yaml
|
||||
parameter_delivery: env
|
||||
parameter_format: dotenv
|
||||
```
|
||||
|
||||
This is allowed because Attune is in pre-production with no users or deployments (per AGENTS.md policy).
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. ✅ **Use default stdin + json** for most actions
|
||||
2. ✅ **Mark sensitive parameters** with `secret: true`
|
||||
3. ✅ **Only use env explicitly** for simple, non-sensitive shell scripts
|
||||
4. ✅ **Test credentials don't appear** in `ps aux` output
|
||||
5. ✅ **Never log sensitive parameters**
|
||||
|
||||
## Example Actions
|
||||
|
||||
See the core pack for examples:
|
||||
|
||||
- `packs/core/actions/http_request.yaml` - Uses stdin + json (handles API tokens)
|
||||
- `packs/core/actions/echo.yaml` - Uses env + dotenv (no secrets)
|
||||
- `packs/core/actions/sleep.yaml` - Uses env + dotenv (no secrets)

# Parameter Delivery Methods
|
||||
|
||||
**Last Updated**: 2025-02-05
|
||||
**Status**: Active Feature
|
||||
|
||||
---
|
||||
|
||||
## Overview
|
||||
|
||||
Attune provides secure parameter passing for actions with two delivery methods: **stdin** (default) and **file** (for large payloads). This document describes parameter delivery, formats, and best practices.
|
||||
|
||||
**Key Design Principle**: Action parameters and environment variables are completely separate:
|
||||
- **Parameters** - Data the action operates on (always secure: stdin or file)
|
||||
- **Environment Variables** - Execution context/configuration (set as env vars, stored in `execution.env_vars`)
|
||||
|
||||
---
|
||||
|
||||
## Security by Design
|
||||
|
||||
### Parameters Are Always Secure
|
||||
|
||||
Action parameters are **never** passed as environment variables. They are always delivered via:
|
||||
- **stdin** (default) - Secure, not visible in process listings
|
||||
- **file** - Secure temporary file with restrictive permissions (0400)
|
||||
|
||||
This ensures parameters (including sensitive data like passwords, API keys, tokens) are never exposed in process listings.
|
||||
|
||||
### Environment Variables Are Separate
|
||||
|
||||
Environment variables provide execution context and configuration:
|
||||
- Stored in `execution.env_vars` (JSONB key-value pairs)
|
||||
- Set as environment variables by the worker
|
||||
- Examples: `ATTUNE_EXECUTION_ID`, custom config values, feature flags
|
||||
- Typically non-sensitive (visible in process environment)
|
||||
|
||||
---
|
||||
|
||||
## Parameter Delivery Methods
|
||||
|
||||
### 1. Standard Input (`stdin`)
|
||||
|
||||
**Security**: ✅ **High** - Not visible in process listings
|
||||
**Use Case**: Sensitive data, structured parameters, credentials
|
||||
|
||||
Parameters are serialized in the specified format and passed via stdin. A delimiter `---ATTUNE_PARAMS_END---` separates parameters from secrets.
|
||||
|
||||
**Example** (this is the default):
|
||||
```yaml
|
||||
parameter_delivery: stdin
|
||||
parameter_format: json
|
||||
```
|
||||
|
||||
**Environment variables set**:
|
||||
- `ATTUNE_PARAMETER_DELIVERY=stdin`
|
||||
- `ATTUNE_PARAMETER_FORMAT=json`
|
||||
|
||||
**Stdin content (JSON format)**:
|
||||
```
|
||||
{"message":"Hello","count":42,"enabled":true}
|
||||
---ATTUNE_PARAMS_END---
|
||||
{"api_key":"secret123","db_password":"pass456"}
|
||||
```
|
||||
|
||||
**Python script example**:
|
||||
```python
|
||||
#!/usr/bin/env python3
|
||||
import sys
|
||||
import json
|
||||
|
||||
def read_stdin_params():
|
||||
"""Read parameters and secrets from stdin."""
|
||||
content = sys.stdin.read()
|
||||
parts = content.split('---ATTUNE_PARAMS_END---')
|
||||
|
||||
# Parse parameters
|
||||
params = json.loads(parts[0].strip()) if parts[0].strip() else {}
|
||||
|
||||
# Parse secrets (if present)
|
||||
secrets = {}
|
||||
if len(parts) > 1 and parts[1].strip():
|
||||
secrets = json.loads(parts[1].strip())
|
||||
|
||||
return params, secrets
|
||||
|
||||
params, secrets = read_stdin_params()
|
||||
message = params.get('message', 'default')
|
||||
api_key = secrets.get('api_key')
|
||||
print(f"Message: {message}")
|
||||
```
|
||||
|
||||
**Shell script example**:
|
||||
```bash
|
||||
#!/bin/bash
|
||||
|
||||
# Read parameters from stdin (JSON format)
|
||||
read -r PARAMS_JSON
|
||||
# Parse JSON (requires jq)
|
||||
MESSAGE=$(echo "$PARAMS_JSON" | jq -r '.message // "default"')
|
||||
COUNT=$(echo "$PARAMS_JSON" | jq -r '.count // 0')
|
||||
|
||||
echo "Message: $MESSAGE, Count: $COUNT"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 2. Temporary File (`file`)
|
||||
|
||||
**Security**: ✅ **High** - File has restrictive permissions (owner read-only)
|
||||
**Use Case**: Large parameter payloads, sensitive data, actions that need random access to parameters
|
||||
|
||||
Parameters are written to a temporary file with restrictive permissions (`0400` on Unix). The file path is provided via the `ATTUNE_PARAMETER_FILE` environment variable.
|
||||
|
||||
**Example**:
|
||||
```yaml
|
||||
# Explicitly set to file
|
||||
parameter_delivery: file
|
||||
parameter_format: yaml
|
||||
```
|
||||
|
||||
**Environment variables set**:
|
||||
- `ATTUNE_PARAMETER_DELIVERY=file`
|
||||
- `ATTUNE_PARAMETER_FORMAT=yaml`
|
||||
- `ATTUNE_PARAMETER_FILE=/tmp/attune-params-abc123.yaml`
|
||||
|
||||
**File content (YAML format)**:
|
||||
```yaml
|
||||
message: Hello
|
||||
count: 42
|
||||
enabled: true
|
||||
```
|
||||
|
||||
**Python script example**:
|
||||
```python
|
||||
#!/usr/bin/env python3
|
||||
import os
|
||||
import yaml
|
||||
|
||||
def read_file_params():
|
||||
"""Read parameters from temporary file."""
|
||||
param_file = os.environ.get('ATTUNE_PARAMETER_FILE')
|
||||
if not param_file:
|
||||
return {}
|
||||
|
||||
with open(param_file, 'r') as f:
|
||||
return yaml.safe_load(f)
|
||||
|
||||
params = read_file_params()
|
||||
message = params.get('message', 'default')
|
||||
count = params.get('count', 0)
|
||||
print(f"Message: {message}, Count: {count}")
|
||||
```
|
||||
|
||||
**Shell script example**:
|
||||
```bash
|
||||
#!/bin/bash
|
||||
|
||||
# Read from parameter file
|
||||
PARAM_FILE="${ATTUNE_PARAMETER_FILE}"
|
||||
if [ -f "$PARAM_FILE" ]; then
|
||||
# Parse YAML (requires yq or similar)
|
||||
MESSAGE=$(yq eval '.message // "default"' "$PARAM_FILE")
|
||||
COUNT=$(yq eval '.count // 0' "$PARAM_FILE")
|
||||
echo "Message: $MESSAGE, Count: $COUNT"
|
||||
fi
|
||||
```
|
||||
|
||||
**Note**: The temporary file is automatically deleted after the action completes.
|
||||
|
||||
---
|
||||
|
||||
## Parameter Formats
|
||||
|
||||
### 1. JSON (`json`)
|
||||
|
||||
**Format**: JSON object
|
||||
**Best For**: Structured data, Python/Node.js actions, complex parameters
|
||||
**Type Preservation**: Yes (strings, numbers, booleans, arrays, objects)
|
||||
|
||||
**Example**:
|
||||
```json
|
||||
{
|
||||
"message": "Hello, World!",
|
||||
"count": 42,
|
||||
"enabled": true,
|
||||
"tags": ["prod", "api"],
|
||||
"config": {
|
||||
"timeout": 30,
|
||||
"retries": 3
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 2. Dotenv (`dotenv`)
|
||||
|
||||
**Format**: `KEY='VALUE'` (one per line)
|
||||
**Best For**: Simple key-value pairs when needed
|
||||
**Type Preservation**: No (all values are strings)
|
||||
|
||||
**Example**:
|
||||
```
|
||||
MESSAGE='Hello, World!'
|
||||
COUNT='42'
|
||||
ENABLED='true'
|
||||
```
|
||||
|
||||
**Escaping**: Single quotes in values are escaped as `'\''`
|
||||
|
||||
---
|
||||
|
||||
### 3. YAML (`yaml`)
|
||||
|
||||
**Format**: YAML document
|
||||
**Best For**: Human-readable structured data, complex configurations
|
||||
**Type Preservation**: Yes (strings, numbers, booleans, arrays, objects)
|
||||
|
||||
**Example**:
|
||||
```yaml
|
||||
message: Hello, World!
|
||||
count: 42
|
||||
enabled: true
|
||||
tags:
|
||||
- prod
|
||||
- api
|
||||
config:
|
||||
timeout: 30
|
||||
retries: 3
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Configuration in Action YAML
|
||||
|
||||
Add these fields to your action metadata file:
|
||||
|
||||
```yaml
|
||||
name: my_action
|
||||
ref: mypack.my_action
|
||||
description: "My secure action"
|
||||
runner_type: python
|
||||
entry_point: my_action.py
|
||||
|
||||
# Parameter delivery configuration (optional - these are the defaults)
|
||||
# parameter_delivery: stdin # Options: stdin, file (default: stdin)
|
||||
# parameter_format: json # Options: json, dotenv, yaml (default: json)
|
||||
|
||||
parameters:
|
||||
type: object
|
||||
properties:
|
||||
api_key:
|
||||
type: string
|
||||
description: "API key for authentication"
|
||||
secret: true # Mark sensitive parameters
|
||||
message:
|
||||
type: string
|
||||
description: "Message to process"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Best Practices
|
||||
|
||||
### 1. Choose the Right Delivery Method
|
||||
|
||||
| Scenario | Recommended Delivery | Recommended Format |
|
||||
|----------|---------------------|-------------------|
|
||||
| Most actions (default) | `stdin` | `json` |
|
||||
| Sensitive credentials | `stdin` (default) | `json` (default) |
|
||||
| Large parameter payloads (>1MB) | `file` | `json` or `yaml` |
|
||||
| Complex structured data | `stdin` (default) | `json` (default) |
|
||||
| Shell scripts | `stdin` (default) | `json` or `dotenv` |
|
||||
| Python/Node.js actions | `stdin` (default) | `json` (default) |
|
||||
|
||||
### 2. Mark Sensitive Parameters
|
||||
|
||||
Always mark sensitive parameters with `secret: true` in the parameter schema:
|
||||
|
||||
```yaml
|
||||
parameters:
|
||||
type: object
|
||||
properties:
|
||||
password:
|
||||
type: string
|
||||
secret: true
|
||||
api_token:
|
||||
type: string
|
||||
secret: true
|
||||
```
|
||||
|
||||
### 3. Handle Missing Parameters Gracefully
|
||||
|
||||
```python
|
||||
# Python example
|
||||
params = read_params()
|
||||
api_key = params.get('api_key')
|
||||
if not api_key:
|
||||
print("ERROR: api_key parameter is required", file=sys.stderr)
|
||||
sys.exit(1)
|
||||
```
|
||||
|
||||
```bash
|
||||
# Shell example
|
||||
if [ -z "$ATTUNE_ACTION_API_KEY" ]; then
|
||||
echo "ERROR: api_key parameter is required" >&2
|
||||
exit 1
|
||||
fi
|
||||
```
|
||||
|
||||
### 4. Validate Parameter Format
|
||||
|
||||
Check the `ATTUNE_PARAMETER_DELIVERY` environment variable to determine how parameters were delivered:
|
||||
|
||||
```python
|
||||
import os
|
||||
|
||||
delivery_method = os.environ.get('ATTUNE_PARAMETER_DELIVERY', 'env')
|
||||
param_format = os.environ.get('ATTUNE_PARAMETER_FORMAT', 'dotenv')
|
||||
|
||||
if delivery_method == 'env':
|
||||
# Read from environment variables
|
||||
params = read_env_params()
|
||||
elif delivery_method == 'stdin':
|
||||
# Read from stdin
|
||||
params = read_stdin_params()
|
||||
elif delivery_method == 'file':
|
||||
# Read from file
|
||||
params = read_file_params()
|
||||
```
|
||||
|
||||
### 5. Clean Up Sensitive Data
|
||||
|
||||
For file-based delivery, the system automatically deletes the temporary file. For stdin/env, ensure sensitive data doesn't leak into logs:
|
||||
|
||||
```python
|
||||
# Don't log sensitive parameters
|
||||
logger.info(f"Processing request for user: {params['username']}")
|
||||
# Don't do this:
|
||||
# logger.debug(f"Full params: {params}") # May contain secrets!
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Design Philosophy
|
||||
|
||||
### Parameters vs Environment Variables
|
||||
|
||||
**Action Parameters** (`stdin` or `file`):
|
||||
- Data the action operates on
|
||||
- Always secure (never in environment)
|
||||
- Examples: API payloads, credentials, business data
|
||||
- Stored in `execution.config` → `parameters`
|
||||
- Passed via stdin or temporary file
|
||||
|
||||
**Environment Variables** (`execution.env_vars`):
|
||||
- Execution context and configuration
|
||||
- Set as environment variables by worker
|
||||
- Examples: `ATTUNE_EXECUTION_ID`, custom config, feature flags
|
||||
- Stored in `execution.env_vars` JSONB
|
||||
- Typically non-sensitive
|
||||
|
||||
### Default Behavior (Secure by Default)
|
||||
|
||||
**As of 2025-02-05**: Parameters default to:
|
||||
- `parameter_delivery: stdin`
|
||||
- `parameter_format: json`
|
||||
|
||||
All action parameters are secure by design. There is no option to pass parameters as environment variables.
|
||||
|
||||
### Migration from Environment Variables
|
||||
|
||||
If you were previously passing data as environment variables, you now have two options:
|
||||
|
||||
**Option 1: Move to Parameters** (for action data):
|
||||
```python
|
||||
# Read from stdin
|
||||
import sys, json
|
||||
content = sys.stdin.read()
|
||||
params = json.loads(content.split('---ATTUNE_PARAMS_END---')[0])
|
||||
value = params.get('key')
|
||||
```
|
||||
|
||||
**Option 2: Use execution.env_vars** (for execution context):
|
||||
Store non-sensitive configuration in `execution.env_vars` when creating the execution:
|
||||
```json
|
||||
{
|
||||
"action_ref": "mypack.myaction",
|
||||
"parameters": {"data": "value"},
|
||||
"env_vars": {"CUSTOM_CONFIG": "value"}
|
||||
}
|
||||
```
|
||||
|
||||
Then read from environment in action:
|
||||
```python
|
||||
import os
|
||||
config = os.environ.get('CUSTOM_CONFIG')
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Examples
|
||||
|
||||
### Complete Python Action with Stdin/JSON
|
||||
|
||||
**Action YAML** (`mypack/actions/secure_action.yaml`):
|
||||
```yaml
|
||||
name: secure_action
|
||||
ref: mypack.secure_action
|
||||
description: "Secure action with stdin parameter delivery"
|
||||

|
||||
entry_point: secure_action.py
|
||||
# Uses default stdin + json (no need to specify)

|
||||
```
|
||||
|
||||
**Action Script** (`mypack/actions/secure_action.py`):
|
||||
```python
|

#!/usr/bin/env python3
|
||||

if not api_token or not endpoint:
|
||||
print(json.dumps({"error": "Missing required parameters"}))
|
||||
sys.exit(1)
|
||||
|
||||
headers = {"Authorization": f"Bearer {api_token}"}
|
||||
response = requests.post(endpoint, json=data, headers=headers)
|
||||
|
||||
result = {
|
||||
"status_code": response.status_code,
|
||||
"response": response.json() if response.ok else None,
|

||||
sys.exit(0 if response.ok else 1)
|
||||
|
||||
if __name__ == "__main__":
|
||||
main()
|
||||
```
|
||||
|
||||
### Complete Shell Action with File/YAML
|
||||
|
||||
**Action YAML** (`mypack/actions/process_config.yaml`):
|
||||
```yaml
|
||||
name: process_config
|
||||
ref: mypack.process_config
|
||||
description: "Process configuration with file-based parameter delivery"
|
||||
runner_type: shell
|

entry_point: process_config.sh
|
||||
# Explicitly use file delivery for large configs
|
||||
parameter_delivery: file
|
||||
parameter_format: yaml
|
||||
|
||||
parameters:
|
||||
type: object
|
||||
properties:

|
||||
description: "Configuration object"
|
||||
environment:
|
||||
type: string
|
||||

|
||||
required:
|
||||
- config
|
||||
```
|
||||
|
||||
**Action Script** (`mypack/actions/process_config.sh`):
|
||||
```bash
|
||||
#!/bin/bash
|
||||
set -e
|
||||
|
||||
# Check if parameter file exists
|
||||
if [ -z "$ATTUNE_PARAMETER_FILE" ]; then
|
||||
echo "ERROR: No parameter file provided" >&2
|
||||
exit 1
|
||||
fi
|
||||
|
||||
# Read configuration from YAML file (requires yq)
|
||||
ENVIRONMENT=$(yq eval '.environment // "dev"' "$ATTUNE_PARAMETER_FILE")
|
||||
CONFIG=$(yq eval '.config' "$ATTUNE_PARAMETER_FILE")
|
||||
|
||||
echo "Processing configuration for environment: $ENVIRONMENT"
|
||||
echo "Config: $CONFIG"
|
||||
|
||||
# Process configuration...
|
||||
# Your logic here
|
||||
|
||||
echo "Configuration processed successfully"
|
||||
exit 0
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Environment Variables Reference
|
||||
|
||||
Actions automatically receive these environment variables:
|
||||
|
||||
**System Variables** (always set):
|
||||
- `ATTUNE_EXECUTION_ID` - Current execution ID
|
||||
- `ATTUNE_ACTION_REF` - Action reference (e.g., "mypack.myaction")
|
||||
- `ATTUNE_PARAMETER_DELIVERY` - Delivery method (stdin/file)
|
||||
- `ATTUNE_PARAMETER_FORMAT` - Format used (json/dotenv/yaml)
|
||||
- `ATTUNE_PARAMETER_FILE` - File path (only for file delivery)
|
||||
|
||||
**Custom Variables** (from `execution.env_vars`):
|
||||
Any key-value pairs in `execution.env_vars` are set as environment variables.
|
||||
|
||||
Example:
|
||||
```json
|
||||
{
|
||||
"env_vars": {
|
||||
"LOG_LEVEL": "debug",
|
||||
"RETRY_COUNT": "3"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Action receives:
|
||||
```bash
|
||||
LOG_LEVEL=debug
|
||||
RETRY_COUNT=3
|
||||
```

|
||||
## Support
|
||||
|
||||
For questions or issues related to parameter delivery:
|
||||
1. Check the action logs for parameter delivery metadata
|
||||
2. Verify the `ATTUNE_PARAMETER_DELIVERY` and `ATTUNE_PARAMETER_FORMAT` environment variables
|
||||
3. Test with a simple action first before implementing complex parameter handling
|
||||
4. Review the example actions in the `core` pack for reference implementations

# Pack Installation Workflow API
|
||||
|
||||
This document describes the API endpoints for the Pack Installation Workflow system, which enables downloading, analyzing, building environments, and registering packs through a multi-stage process.
|
||||
|
||||
## Overview
|
||||
|
||||
The pack installation workflow consists of four main stages:
|
||||
|
||||
1. **Download** - Fetch pack source code from various sources (Git, registry, local)
|
||||
2. **Dependencies** - Analyze pack dependencies and runtime requirements
|
||||
3. **Build Environments** - Prepare Python/Node.js runtime environments
|
||||
4. **Register** - Register pack components in the Attune database
|
||||
|
||||
Each stage is exposed as an API endpoint and can be called independently or orchestrated through a workflow.
|
||||
|
||||
## Authentication
|
||||
|
||||
All endpoints require authentication via Bearer token:
|
||||
|
||||
```http
|
||||
Authorization: Bearer <access_token>
|
||||
```
|
||||
|
||||

||||
**Status Codes:**
|
||||
|
||||
- `200 OK` - Environment detection completed
|
||||
- `400 Bad Request` - Invalid request parameters
|
||||
- `401 Unauthorized` - Missing or invalid authentication
|
||||
- `500 Internal Server Error` - Server error during detection

## Action Wrappers
|
||||
|
||||
These API endpoints are wrapped by shell actions in the `core` pack for workflow orchestration:
|
||||
|
||||
### Actions
|
||||
|
||||
1. **`core.download_packs`** - Wraps `/api/v1/packs/download`
|
||||
2. **`core.get_pack_dependencies`** - Wraps `/api/v1/packs/dependencies`
|
||||
3. **`core.build_pack_envs`** - Wraps `/api/v1/packs/build-envs`
|
||||
4. **`core.register_packs`** - Wraps `/api/v1/packs/register-batch`
|
||||
|
||||
### Action Parameters
|
||||
|
||||
Each action accepts parameters that map directly to the API request body, plus:
|
||||
|
||||
- `api_url` (string, optional) - API base URL
|
||||
- Default: `http://localhost:8080`
|
||||
- `api_token` (string, optional) - Authentication token
|
||||
- If not provided, uses system authentication
|
||||
|
||||
### Example Action Execution
|
||||
|
||||
```bash
|
||||
attune action execute core.download_packs \
|
||||
--param packs='["core","aws"]' \
|
||||
--param destination_dir=/tmp/packs
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Workflow Example
|
||||
|
||||
Complete pack installation workflow using the API:
|
||||
|
||||
```yaml
|
||||
# workflows/install_pack.yaml
|
||||
name: install_pack
|
||||
description: Complete pack installation workflow
|
||||
version: 1.0.0
|
||||
|
||||
input:
|
||||
- pack_source
|
||||
- destination_dir
|
||||
|
||||
tasks:
|
||||
# Stage 1: Download
|
||||
download:
|
||||
action: core.download_packs
|
||||
input:
|
||||
packs:
|
||||
- <% ctx().pack_source %>
|
||||
destination_dir: <% ctx().destination_dir %>
|
||||
next:
|
||||
- when: <% succeeded() %>
|
||||
publish:
|
||||
- pack_paths: <% result().downloaded_packs.select($.pack_path) %>
|
||||
do: analyze_deps
|
||||
|
||||
# Stage 2: Analyze Dependencies
|
||||
analyze_deps:
|
||||
action: core.get_pack_dependencies
|
||||
input:
|
||||
pack_paths: <% ctx().pack_paths %>
|
||||
next:
|
||||
- when: <% succeeded() and result().missing_dependencies.len() = 0 %>
|
||||
do: build_envs
|
||||
- when: <% succeeded() and result().missing_dependencies.len() > 0 %>
|
||||
do: fail
|
||||
publish:
|
||||
- error: "Missing dependencies: <% result().missing_dependencies %>"
|
||||
|
||||
# Stage 3: Build Environments
|
||||
build_envs:
|
||||
action: core.build_pack_envs
|
||||
input:
|
||||
pack_paths: <% ctx().pack_paths %>
|
||||
next:
|
||||
- when: <% succeeded() %>
|
||||
do: register
|
||||
|
||||
# Stage 4: Register Packs
|
||||
register:
|
||||
action: core.register_packs
|
||||
input:
|
||||
pack_paths: <% ctx().pack_paths %>
|
||||
skip_tests: false
|
||||
|
||||
output:
|
||||
- registered_packs: <% task(register).result.registered_packs %>
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Error Handling
|
||||
|
||||
All endpoints return consistent error responses:
|
||||
|
||||
```json
|
||||
{
|
||||
"error": "Error message",
|
||||
"message": "Detailed error description",
|
||||
"status": 400
|
||||
}
|
||||
```
|
||||
|
||||
### Common Error Scenarios
|
||||
|
||||
1. **Missing Authentication**
|
||||
- Status: 401
|
||||
- Solution: Provide valid Bearer token
|
||||
|
||||
2. **Invalid Pack Path**
|
||||
- Reported in `errors` array within 200 response
|
||||
- Solution: Verify pack paths exist and are readable
|
||||
|
||||
3. **Missing Dependencies**
|
||||
- Reported in `missing_dependencies` array
|
||||
- Solution: Install dependencies first or use `skip_deps: true`
|
||||
|
||||
4. **Runtime Not Available**
|
||||
- Reported in `failed_environments` array
|
||||
- Solution: Install required Python/Node.js version
|
||||
|
||||
5. **Pack Already Registered**
|
||||
- Status: 400 (or in `failed_packs` for batch)
|
||||
- Solution: Use `force: true` to re-register
|
||||
|
||||
---
|
||||
|
||||
## Best Practices
|
||||
|
||||
### 1. Download Strategy
|
||||
|
||||
- **Registry packs**: Use pack names (`"core"`, `"aws"`)
|
||||
- **Git repos**: Use full URLs with version tags
|
||||
- **Local packs**: Use absolute paths
|
||||
|
||||
### 2. Dependency Management
|
||||
|
||||
- Always run dependency analysis after download
|
||||
- Install missing dependencies before registration
|
||||
- Use pack registry to resolve dependency versions
|
||||
|
||||
### 3. Environment Building
|
||||
|
||||
- Check for existing environments before rebuilding
|
||||
- Use `force_rebuild: true` sparingly (time-consuming)
|
||||
- Verify Python/Node.js availability before starting
|
||||
|
||||
### 4. Registration
|
||||
|
||||
- Run tests unless in development (`skip_tests: false` in production)
|
||||
- Use validation to catch configuration errors early
|
||||
- Enable `force: true` only when intentionally updating
|
||||
|
||||
### 5. Error Recovery
|
||||
|
||||
- Check individual pack results in batch operations
|
||||
- Retry failed downloads with exponential backoff
|
||||
- Log all errors for troubleshooting
|
||||

## CLI Integration
|
||||
|
||||
Use the Attune CLI to execute pack installation actions:
|
||||
|
||||
```bash
|
||||
# Download packs
|
||||
attune action execute core.download_packs \
|
||||
--param packs='["core"]' \
|
||||
--param destination_dir=/tmp/packs
|
||||
|
||||
# Analyze dependencies
|
||||
attune action execute core.get_pack_dependencies \
|
||||
--param pack_paths='["/tmp/packs/core"]'
|
||||
|
||||
# Build environments
|
||||
attune action execute core.build_pack_envs \
|
||||
--param pack_paths='["/tmp/packs/core"]'
|
||||
|
||||
# Register packs
|
||||
attune action execute core.register_packs \
|
||||
--param pack_paths='["/tmp/packs/core"]'
|
||||
```
|
||||
|
||||

### Install Pack from Source
|
||||
|
||||
Install a pack from git, HTTP, or registry:
|
||||
|
||||
```bash
|
||||
# From git repository (HTTPS)
|
||||
attune pack install https://github.com/attune/pack-slack.git
|
||||
|
||||
# From git repository with specific ref
|
||||

|
||||
|
||||
### Register Pack from Local Path
|
||||
|
||||
Register a pack that's already on disk:
|
||||
|
||||
```bash
|
||||
# Register pack from directory
|
||||
attune pack register /path/to/pack
|
||||
|
||||
# With options
|
||||
attune pack register /path/to/pack \
|
||||

|
||||
--skip-tests
|
||||
```
|
||||
|
||||
**Options:**
|
||||
- `--force` - Replace existing pack
|
||||
- `--skip-tests` - Skip running pack tests
|
||||
|
||||
## Using Actions Directly
|
||||
|
||||
The pack installation workflow consists of individual actions that can be run separately:
|
||||
|
||||
### 1. Download Packs
|
||||
|
||||
```bash
|
||||
# Download one or more packs
|
||||
attune action execute core.download_packs \
|
||||
--param packs='["https://github.com/attune/pack-slack.git"]' \
|
||||
--param destination_dir=/tmp/attune-packs \
|
||||
--wait
|
||||
|
||||
# Multiple packs
|
||||
attune action execute core.download_packs \
|
||||
--param packs='["slack@1.0.0","aws@2.0.0"]' \
|
||||
--param destination_dir=/tmp/attune-packs \
|
||||
--param registry_url=https://registry.attune.io/index.json \
|
||||
--wait
|
||||
|
||||
# Get JSON output
|
||||
attune action execute core.download_packs \
|
||||
--param packs='["https://github.com/attune/pack-slack.git"]' \
|
||||
--param destination_dir=/tmp/attune-packs \
|
||||
--wait --json
|
||||
```
|
||||
|
||||
### 2. Get Pack Dependencies
|
||||
|
||||
```bash
|
||||
# Analyze pack dependencies
|
||||
attune action execute core.get_pack_dependencies \
|
||||
--param pack_paths='["/tmp/attune-packs/slack"]' \
|
||||
--wait
|
||||
|
||||
# With JSON output to check for missing dependencies
|
||||
result=$(attune action execute core.get_pack_dependencies \
|
||||
--param pack_paths='["/tmp/attune-packs/slack"]' \
|
||||
--wait --json)
|
||||
|
||||
echo "$result" | jq '.result.missing_dependencies'
|
||||
```
|
||||
|
||||
### 3. Build Pack Environments
|
||||
|
||||
```bash
|
||||
# Build Python and Node.js environments
|
||||
attune action execute core.build_pack_envs \
|
||||
--param pack_paths='["/tmp/attune-packs/slack"]' \
|
||||
--wait
|
||||
|
||||
# Skip Node.js environment
|
||||
attune action execute core.build_pack_envs \
|
||||
--param pack_paths='["/tmp/attune-packs/slack"]' \
|
||||
--param skip_nodejs=true \
|
||||
--wait
|
||||
|
||||
# Force rebuild
|
||||
attune action execute core.build_pack_envs \
|
||||
--param pack_paths='["/tmp/attune-packs/slack"]' \
|
||||
--param force_rebuild=true \
|
||||
--wait
|
||||
```
|
||||
|
||||
### 4. Register Packs
|
||||
|
||||
```bash
|
||||
# Register downloaded packs
|
||||
attune action execute core.register_packs \
|
||||
--param pack_paths='["/tmp/attune-packs/slack"]' \
|
||||
--wait
|
||||
|
||||
# With force and skip tests
|
||||
attune action execute core.register_packs \
|
||||
--param pack_paths='["/tmp/attune-packs/slack"]' \
|
||||
--param force=true \
|
||||
--param skip_tests=true \
|
||||
--wait
|
||||
```
|
||||
|
||||
## Using the Workflow
|
||||
|
||||
The `core.install_packs` workflow automates the entire process:
|
||||
|
||||
```bash
|
||||
# Install pack using workflow
|
||||
attune action execute core.install_packs \
|
||||
--param packs='["https://github.com/attune/pack-slack.git"]' \
|
||||
--wait
|
||||
|
||||
# With options
|
||||
attune action execute core.install_packs \
|
||||
--param packs='["slack@1.0.0","aws@2.0.0"]' \
|
||||
--param force=true \
|
||||
--param skip_tests=true \
|
||||
--wait
|
||||
|
||||
# Install with specific git ref
|
||||
attune action execute core.install_packs \
|
||||
--param packs='["https://github.com/attune/pack-slack.git"]' \
|
||||
--param ref_spec=v1.0.0 \
|
||||
--wait
|
||||
```
|
||||
|
||||
**Note**: When the workflow feature is fully implemented, use:
|
||||
```bash
|
||||
attune workflow execute core.install_packs \
|
||||
--input packs='["slack@1.0.0"]'
|
||||
```
|
||||
|
||||
## Management Commands

--param packs='["slack@1.0.0"]' \
|
||||
--param destination_dir=/tmp/test-pack \
|
||||
--wait
|
||||
|
||||
# Check dependencies
|
||||
deps=$(attune action execute core.get_pack_dependencies \
|
||||
--param pack_paths='["/tmp/test-pack/slack"]' \
|
||||
--wait --json)
|
||||
|
||||
# Check for missing dependencies
|
||||
missing=$(echo "$deps" | jq -r '.result.missing_dependencies | length')
|
||||
|
||||

|
||||
### Example 5: Scripted Installation with Error Handling
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
set -e
|
||||
|
||||
PACK_SOURCE="https://github.com/attune/pack-slack.git"

|
||||
--param packs="[\"$PACK_SOURCE\"]" \
|
||||
--param destination_dir="$TEMP_DIR" \
|
||||
--param ref_spec="$PACK_REF" \
|
||||
--wait --json)
|
||||
|
||||
success=$(echo "$download_result" | jq -r '.result.success_count // 0')
|
||||
if [[ "$success" -eq 0 ]]; then
|
||||
echo "Error: Download failed"
|
||||
echo "$download_result" | jq '.result.failed_packs'

# Cleanup
|
||||
rm -rf "$TEMP_DIR"
|
||||
|
||||
echo "Installation complete!"
|
||||
```
|
||||
|
||||
### Example 6: Bulk Pack Installation
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# Install multiple packs from a list
|
||||
|
||||
PACKS=(
|
||||
"slack@1.0.0"
|
||||
"aws@2.1.0"
|
||||
"kubernetes@3.0.0"
|
||||
"datadog@1.5.0"
|
||||
)
|
||||
|
||||
for pack in "${PACKS[@]}"; do
|
||||
echo "Installing: $pack"
|
||||
if attune pack install "$pack" --skip-tests; then
|
||||
echo "✓ $pack installed successfully"
|
||||
else
|
||||
echo "✗ $pack installation failed"
|
||||
fi
|
||||
done
|
||||
```
|
||||
|
||||
## Output Formats
|
||||
|
||||
All commands support multiple output formats:
|
||||
|
||||
```bash
|
||||
# Default table format
|
||||
attune pack list
|
||||
|
||||
# JSON format
|
||||
attune pack list --json
|
||||
attune pack list -j
|
||||
|
||||
# YAML format
|
||||
attune pack list --yaml
|
||||
attune pack list -y
|
||||
```
|
||||
|
||||
## Authentication
|
||||
|
||||
Most commands require authentication:
|
||||
|
||||
```bash
|
||||
# Login first
|
||||
attune auth login
|
||||
|
||||
# Or use a token
|
||||
export ATTUNE_API_TOKEN="your-token-here"
|
||||
attune pack list
|
||||
|
||||
# Or specify token in command
|
||||
attune pack list --api-url http://localhost:8080
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
Configure CLI settings:
|
||||
|
||||
```bash
|
||||
# Set default API URL
|
||||
attune config set api_url http://localhost:8080
|
||||
|
||||
# Set default profile
|
||||
attune config set profile production
|
||||
|
||||
# View configuration
|
||||
attune config show
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
**Authentication errors:**
|
||||
```bash
|
||||
# Re-login
|
||||
attune auth login
|
||||
|
||||
# Check token
|
||||
attune auth token
|
||||
|
||||
# Refresh token
|
||||
attune auth refresh
|
||||
```
|
||||
|
||||
**Pack already exists:**
|
||||
```bash
|
||||
# Use --force to replace
|
||||
attune pack install slack@1.0.0 --force
|
||||
```
|
||||
|
||||
**Network timeouts:**
|
||||
```bash
|
||||
# Increase timeout (via environment variable for now)
|
||||
export ATTUNE_ACTION_TIMEOUT=600
|
||||
attune pack install large-pack@1.0.0
|
||||
```
|
||||
|
||||
**Missing dependencies:**
|
||||
```bash
|
||||
# Install dependencies first
|
||||
attune pack install core@1.0.0
|
||||
attune pack install dependent-pack@1.0.0
|
||||
```

# Docker Layer Optimization Guide
|
||||
|
||||
## Problem Statement
|
||||
|
||||
When building Rust workspace projects in Docker, copying the entire `crates/` directory creates a single Docker layer that gets invalidated whenever **any file** in **any crate** changes. This means:
|
||||
|
||||
- **Before optimization**: Changing one line in `api/src/main.rs` invalidates layers for ALL services (api, executor, worker, sensor, notifier)
|
||||
- **Impact**: Every service rebuild takes ~5-6 minutes instead of ~30 seconds
|
||||
- **Root cause**: Docker's layer caching treats `COPY crates/ ./crates/` as an atomic operation
|
||||
|
||||
## Architecture: Packs as Volumes
|
||||
|
||||
**Important**: The optimized Dockerfiles do NOT copy the `packs/` directory into service images. Packs are content/configuration that should be decoupled from service binaries.
|
||||
|
||||
### Packs Volume Strategy
|
||||
```yaml
|
||||
# docker-compose.yaml
|
||||
volumes:
|
||||
packs_data: # Shared volume for all services
|
||||
|
||||
services:
|
||||
init-packs: # Run-once service that populates packs_data
|
||||
volumes:
|
||||
- ./packs:/source/packs:ro # Source packs from host
|
||||
- packs_data:/opt/attune/packs # Copy to shared volume
|
||||
|
||||
api:
|
||||
volumes:
|
||||
- packs_data:/opt/attune/packs:ro # Mount packs as read-only
|
||||
|
||||
worker:
|
||||
volumes:
|
||||
- packs_data:/opt/attune/packs:ro # All services share same packs
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- ✅ Update packs without rebuilding service images
|
||||
- ✅ Reduce image size (packs not baked in)
|
||||
- ✅ Faster builds (no pack copying during image build)
|
||||
- ✅ Consistent packs across all services
|
||||
|
||||
## The Solution: Selective Crate Copying
|
||||
|
||||
The optimized Dockerfiles use a multi-stage approach that separates dependency caching from source code compilation:
|
||||
|
||||
### Stage 1: Planner (Dependency Caching)
|
||||
```dockerfile
|
||||
# Copy only Cargo.toml files (not source code)
|
||||
COPY Cargo.toml Cargo.lock ./
|
||||
COPY crates/common/Cargo.toml ./crates/common/Cargo.toml
|
||||
COPY crates/api/Cargo.toml ./crates/api/Cargo.toml
|
||||
# ... all other crate manifests
|
||||
|
||||
# Create dummy source files
|
||||
RUN mkdir -p crates/common/src && echo "fn main() {}" > crates/common/src/lib.rs
|
||||
# ... create dummies for all crates
|
||||
|
||||
# Build with dummy source to cache dependencies
|
||||
RUN cargo build --release --bin attune-${SERVICE}
|
||||
```
|
||||
|
||||
**Result**: This layer is only invalidated when dependencies change (Cargo.toml/Cargo.lock modifications).
|
||||
|
||||
### Stage 2: Builder (Selective Source Compilation)
|
||||
```dockerfile
|
||||
# Copy common crate (shared dependency)
|
||||
COPY crates/common/ ./crates/common/
|
||||
|
||||
# Copy ONLY the service being built
|
||||
COPY crates/${SERVICE}/ ./crates/${SERVICE}/
|
||||
|
||||
# Build the actual service
|
||||
RUN cargo build --release --bin attune-${SERVICE}
|
||||
```
|
||||
|
||||
**Result**: This layer is only invalidated when the specific service's code changes (or common crate changes).
|
||||
|
||||
### Stage 3: Runtime (No Packs Copying)
|
||||
```dockerfile
|
||||
# Create directories for volume mount points
|
||||
RUN mkdir -p /opt/attune/packs /opt/attune/logs
|
||||
|
||||
# Note: Packs are NOT copied here
|
||||
# They will be mounted as a volume at runtime from packs_data volume
|
||||
```
|
||||
|
||||
**Result**: Service images contain only binaries and configs, not packs. Packs are mounted at runtime.
|
||||
|
||||
## Performance Comparison
|
||||
|
||||
### Before Optimization (Old Dockerfile)
|
||||
```
|
||||
Scenario: Change api/src/routes/actions.rs
|
||||
- Layer invalidated: COPY crates/ ./crates/
|
||||
- Rebuilds: All dependencies + all crates
|
||||
- Time: ~5-6 minutes
|
||||
- Size: Full dependency rebuild
|
||||
```
|
||||
|
||||
### After Optimization (New Dockerfile)
|
||||
```
|
||||
Scenario: Change api/src/routes/actions.rs
|
||||
- Layer invalidated: COPY crates/api/ ./crates/api/
|
||||
- Rebuilds: Only attune-api binary
|
||||
- Time: ~30-60 seconds
|
||||
- Size: Minimal incremental compilation
|
||||
```
|
||||
|
||||
### Dependency Change Comparison
|
||||
```
|
||||
Scenario: Add new dependency to Cargo.toml
|
||||
- Before: ~5-6 minutes (full rebuild)
|
||||
- After: ~3-4 minutes (dependency cached separately)
|
||||
```
|
||||
|
||||
## Implementation
|
||||
|
||||
### Using Optimized Dockerfiles
|
||||
|
||||
The optimized Dockerfiles are available as:
|
||||
- `docker/Dockerfile.optimized` - For main services (api, executor, sensor, notifier)
|
||||
- `docker/Dockerfile.worker.optimized` - For worker services
|
||||
|
||||
#### Option 1: Switch to Optimized Dockerfiles (Recommended)
|
||||
|
||||
Update `docker-compose.yaml`:
|
||||
|
||||
```yaml
|
||||
services:
|
||||
api:
|
||||
build:
|
||||
context: .
|
||||
dockerfile: docker/Dockerfile.optimized # Changed from docker/Dockerfile
|
||||
args:
|
||||
SERVICE: api
|
||||
```
|
||||
|
||||
#### Option 2: Replace Existing Dockerfiles
|
||||
|
||||
```bash
|
||||
# Backup current Dockerfiles
|
||||
cp docker/Dockerfile docker/Dockerfile.backup
|
||||
cp docker/Dockerfile.worker docker/Dockerfile.worker.backup
|
||||
|
||||
# Replace with optimized versions
|
||||
mv docker/Dockerfile.optimized docker/Dockerfile
|
||||
mv docker/Dockerfile.worker.optimized docker/Dockerfile.worker
|
||||
```
|
||||
|
||||
### Testing the Optimization
|
||||
|
||||
1. **Clean build (first time)**:
|
||||
```bash
|
||||
docker compose build --no-cache api
|
||||
# Time: ~5-6 minutes (expected, building from scratch)
|
||||
```
|
||||
|
||||
2. **Incremental build (change API code)**:
|
||||
```bash
|
||||
# Edit attune/crates/api/src/routes/actions.rs
|
||||
echo "// test comment" >> crates/api/src/routes/actions.rs
|
||||
|
||||
docker compose build api
|
||||
# Time: ~30-60 seconds (optimized, only rebuilds API)
|
||||
```
|
||||
|
||||
3. **Verify other services not affected**:
|
||||
```bash
|
||||
# The worker service should still use cached layers
|
||||
docker compose build worker-shell
|
||||
# Time: ~5 seconds (uses cache, no rebuild needed)
|
||||
```
|
||||
|
||||
## How It Works: Docker Layer Caching
|
||||
|
||||
Docker builds images in layers, and each instruction (`COPY`, `RUN`, etc.) creates a new layer. Layers are cached and reused if:
|
||||
1. The instruction hasn't changed
|
||||
2. The context (files being copied) hasn't changed
|
||||
3. All previous layers are still valid
|
||||
|
||||
### Old Approach (Unoptimized)
|
||||
```
|
||||
Layer 1: COPY Cargo.toml Cargo.lock
|
||||
Layer 2: COPY crates/ ./crates/ ← Invalidated on ANY crate change
|
||||
Layer 3: RUN cargo build ← Always rebuilds everything
|
||||
```
|
||||
|
||||
### New Approach (Optimized)
|
||||
```
|
||||
Stage 1 (Planner):
|
||||
Layer 1: COPY Cargo.toml Cargo.lock ← Only invalidated on dependency changes
|
||||
Layer 2: COPY */Cargo.toml ← Only invalidated on dependency changes
|
||||
Layer 3: RUN cargo build (dummy) ← Caches compiled dependencies
|
||||
|
||||
Stage 2 (Builder):
|
||||
Layer 4: COPY crates/common/ ← Invalidated on common changes
|
||||
Layer 5: COPY crates/${SERVICE}/ ← Invalidated on service-specific changes
|
||||
Layer 6: RUN cargo build ← Only recompiles changed crates
|
||||
```
|
||||
|
||||
## BuildKit Cache Mounts
|
||||
|
||||
The optimized Dockerfiles also use BuildKit cache mounts for additional speedup:
|
||||
|
||||
```dockerfile
|
||||
RUN --mount=type=cache,target=/usr/local/cargo/registry,sharing=shared \
|
||||
--mount=type=cache,target=/usr/local/cargo/git,sharing=shared \
|
||||
--mount=type=cache,target=/build/target,id=target-builder-${SERVICE} \
|
||||
cargo build --release
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- **Cargo registry**: Downloaded crates persist between builds
|
||||
- **Cargo git**: Git dependencies persist between builds
|
||||
- **Target directory**: Compilation artifacts persist between builds
|
||||
- **Optimized sharing**: Registry/git use `sharing=shared` for concurrent access
|
||||
- **Service-specific caches**: Target directory uses unique cache IDs to prevent conflicts
|
||||
|
||||
**Cache Strategy**:
|
||||
- **`sharing=shared`**: Registry and git caches (cargo handles concurrent access safely)
|
||||
- **Service-specific IDs**: Target caches use `id=target-builder-${SERVICE}` to prevent conflicts
|
||||
- **Result**: Safe parallel builds without serialization overhead (4x faster)
|
||||
- **See**: `docs/QUICKREF-buildkit-cache-strategy.md` for detailed explanation
|
||||
|
||||
**Requirements**:
|
||||
- Enable BuildKit: `export DOCKER_BUILDKIT=1`
|
||||
- Or use docker-compose which enables it automatically
|
||||
|
||||
## Advanced: Parallel Builds
|
||||
|
||||
With the optimized Dockerfiles, you can safely build multiple services in parallel:
|
||||
|
||||
```bash
|
||||
# Build all services in parallel (4 workers)
|
||||
docker compose build --parallel 4
|
||||
|
||||
# Or build specific services
|
||||
docker compose build api executor worker-shell
|
||||
```
|
||||
|
||||
**Optimized for Parallel Builds**:
|
||||
- ✅ Registry/git caches use `sharing=shared` (concurrent-safe)
|
||||
- ✅ Target caches use service-specific IDs (no conflicts)
|
||||
- ✅ **4x faster** than old `sharing=locked` strategy
|
||||
- ✅ No race conditions or "File exists" errors
|
||||
|
||||
**Why it's safe**: Each service compiles different binaries (api vs executor vs worker), so their target caches don't conflict. Cargo's registry and git caches are inherently concurrent-safe.
|
||||
|
||||
See `docs/QUICKREF-buildkit-cache-strategy.md` for detailed explanation of the cache strategy.
|
||||
|
||||
## Tradeoffs and Considerations
|
||||
|
||||
### Advantages
|
||||
- ✅ **Faster incremental builds**: 30 seconds vs 5 minutes
|
||||
- ✅ **Better cache utilization**: Only rebuild what changed
|
||||
- ✅ **Smaller layer diffs**: More efficient CI/CD pipelines
|
||||
- ✅ **Reduced build costs**: Less CPU time in CI environments
|
||||
|
||||
### Disadvantages
|
||||
- ❌ **More complex Dockerfiles**: Additional planner stage
|
||||
- ❌ **Slightly longer first build**: Dummy compilation overhead (~30 seconds)
|
||||
- ❌ **Manual manifest copying**: Need to list all crates explicitly
|
||||
|
||||
### When to Use
|
||||
- ✅ **Active development**: Frequent code changes benefit from fast rebuilds
|
||||
- ✅ **CI/CD pipelines**: Reduce build times and costs
|
||||
- ✅ **Monorepo workspaces**: Multiple services sharing common code
|
||||
|
||||
### When NOT to Use
|
||||
- ❌ **Single-crate projects**: No benefit for non-workspace projects
|
||||
- ❌ **Infrequent builds**: Complexity not worth it for rare builds
|
||||
- ❌ **Dockerfile simplicity required**: Stick with basic approach
|
||||
|
||||
## Pack Binaries
|
||||
|
||||
Pack binaries (like `attune-core-timer-sensor`) need to be built separately and placed in `./packs/` before starting docker-compose.
|
||||
|
||||
### Building Pack Binaries
|
||||
|
||||
Use the provided script:
|
||||
```bash
|
||||
./scripts/build-pack-binaries.sh
|
||||
```
|
||||
|
||||
Or manually:
|
||||
```bash
|
||||
# Build pack binaries in Docker with GLIBC compatibility
|
||||
docker build -f docker/Dockerfile.pack-binaries -t attune-pack-builder .
|
||||
|
||||
# Extract binaries
|
||||
docker create --name pack-tmp attune-pack-builder
|
||||
docker cp pack-tmp:/pack-binaries/attune-core-timer-sensor ./packs/core/sensors/
|
||||
docker rm pack-tmp
|
||||
|
||||
# Make executable
|
||||
chmod +x ./packs/core/sensors/attune-core-timer-sensor
|
||||
```
|
||||
|
||||
The `init-packs` service will copy these binaries (along with other pack files) into the `packs_data` volume when docker-compose starts.
|
||||
|
||||
### Why Separate Pack Binaries?
|
||||
|
||||
- **GLIBC Compatibility**: Built in Debian Bookworm for GLIBC 2.36 compatibility
|
||||
- **Decoupled Updates**: Update pack binaries without rebuilding service images
|
||||
- **Smaller Service Images**: Service images don't include pack compilation stages
|
||||
- **Cleaner Architecture**: Packs are content, services are runtime
|
||||
|
||||
## Maintenance
|
||||
|
||||
### Adding New Crates
|
||||
|
||||
When adding a new crate to the workspace:
|
||||
|
||||
1. **Update `Cargo.toml`** workspace members:
|
||||
```toml
|
||||
[workspace]
|
||||
members = [
|
||||
"crates/common",
|
||||
"crates/new-service", # Add this
|
||||
]
|
||||
```
|
||||
|
||||
2. **Update optimized Dockerfiles** (both planner and builder stages):
|
||||
```dockerfile
|
||||
# In planner stage
|
||||
COPY crates/new-service/Cargo.toml ./crates/new-service/Cargo.toml
|
||||
RUN mkdir -p crates/new-service/src && echo "fn main() {}" > crates/new-service/src/main.rs
|
||||
|
||||
# In builder stage
|
||||
COPY crates/new-service/Cargo.toml ./crates/new-service/Cargo.toml
|
||||
```
|
||||
|
||||
3. **Test the build**:
|
||||
```bash
|
||||
docker compose build new-service
|
||||
```
|
||||
|
||||
### Updating Packs
|
||||
|
||||
Packs are mounted as volumes, so updating them doesn't require rebuilding service images:
|
||||
|
||||
1. **Update pack files** in `./packs/`:
|
||||
```bash
|
||||
# Edit pack files
|
||||
vim packs/core/actions/my_action.yaml
|
||||
```
|
||||
|
||||
2. **Rebuild pack binaries** (if needed):
|
||||
```bash
|
||||
./scripts/build-pack-binaries.sh
|
||||
```
|
||||
|
||||
3. **Restart services** to pick up changes:
|
||||
```bash
|
||||
docker compose restart
|
||||
```
|
||||
|
||||
No image rebuild required!
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Build fails with "crate not found"
|
||||
**Cause**: Missing crate manifest in COPY instructions
|
||||
**Fix**: Add the crate's Cargo.toml to both planner and builder stages
|
||||
|
||||
### Changes not reflected in build
|
||||
**Cause**: Docker using stale cached layers
|
||||
**Fix**: Force rebuild with `docker compose build --no-cache <service>`
|
||||
|
||||
### "File exists" errors during parallel builds
|
||||
**Cause**: Cache mount conflicts
|
||||
**Fix**: Already handled by `sharing=locked` in optimized Dockerfiles
|
||||
|
||||
### Slow builds after dependency changes
|
||||
**Cause**: Expected behavior - dependencies must be recompiled
|
||||
**Fix**: This is normal; optimization helps with code changes, not dependency changes
|
||||
|
||||
## Alternative Approaches
|
||||
|
||||
### cargo-chef (Not Used)
|
||||
The `cargo-chef` tool provides similar optimization but requires additional tooling:
|
||||
- Pros: Automatic dependency detection, no manual manifest copying
|
||||
- Cons: Extra dependency, learning curve, additional maintenance
|
||||
|
||||
We opted for the manual approach because:
|
||||
- Simpler to understand and maintain
|
||||
- No external dependencies
|
||||
- Full control over the build process
|
||||
- Easier to debug issues
|
||||
|
||||
### Volume Mounts for Development
|
||||
For local development, consider mounting the source as a volume:
|
||||
```yaml
|
||||
volumes:
|
||||
- ./crates/api:/build/crates/api
|
||||
```
|
||||
- Pros: Instant code updates without rebuilds
|
||||
- Cons: Not suitable for production images

||||

||||

||||
## Summary
|
||||
|
||||
The optimized Docker build strategy significantly reduces build times by:
|
||||
1. **Separating dependency resolution from source compilation**
|
||||
2. **Only copying the specific crate being built** (plus common dependencies)
|
||||
3. **Using BuildKit cache mounts** to persist compilation artifacts
|
||||
4. **Mounting packs as volumes** instead of copying them into images
|
||||
|
||||
**Key Architecture Principles**:
|
||||
- **Service images**: Contain only compiled binaries and configuration
|
||||
- **Packs**: Mounted as volumes, updated independently of services
|
||||
- **Pack binaries**: Built separately with GLIBC compatibility
|
||||
- **Volume strategy**: `init-packs` service populates shared `packs_data` volume
|
||||
|
||||
**Result**:
|
||||
- Incremental builds drop from 5-6 minutes to 30-60 seconds
|
||||
- Pack updates don't require image rebuilds
|
||||
- Service images are smaller and more focused
|
||||
- Docker-based development workflows are practical for Rust workspaces

# Pack Installation Actions
|
||||
|
||||
This document describes the pack installation actions that automate the process of downloading, analyzing, building environments, and registering packs in Attune.
|
||||
|
||||
## Overview
|
||||
|
||||
The pack installation system consists of four core actions that work together to automate pack installation:
|
||||
|
||||
1. **`core.download_packs`** - Downloads packs from git, HTTP, or registry sources
|
||||
2. **`core.get_pack_dependencies`** - Analyzes pack dependencies and runtime requirements
|
||||
3. **`core.build_pack_envs`** - Creates Python virtualenvs and Node.js environments
|
||||
4. **`core.register_packs`** - Registers packs with the Attune API and database
|
||||
|
||||
These actions are designed to be used in workflows (like `core.install_packs`) or independently via the CLI/API.
|
||||
|
||||
## Actions
|
||||
|
||||
### 1. core.download_packs
|
||||
|
||||
Downloads packs from various sources to a local directory.
|
||||
|
||||
**Source Types:**
|
||||
- **Git repositories**: URLs ending in `.git` or starting with `git@`
|
||||
- **HTTP archives**: URLs with `http://` or `https://` (tar.gz, zip)
|
||||
- **Registry references**: Pack name with optional version (e.g., `slack@1.0.0`)
|
||||
|
||||
**Parameters:**
|
||||
|
||||
| Parameter | Type | Required | Default | Description |
|
||||
|-----------|------|----------|---------|-------------|
|
||||
| `packs` | array[string] | Yes | - | List of pack sources to download |
|
||||
| `destination_dir` | string | Yes | - | Directory where packs will be downloaded |
|
||||
| `registry_url` | string | No | `https://registry.attune.io/index.json` | Pack registry URL |
|
||||
| `ref_spec` | string | No | - | Git reference (branch/tag/commit) for git sources |
|
||||
| `timeout` | integer | No | 300 | Download timeout in seconds per pack |
|
||||
| `verify_ssl` | boolean | No | true | Verify SSL certificates for HTTPS |
|
||||
| `api_url` | string | No | `http://localhost:8080` | Attune API URL |

|
||||
"total_tests": 5,
|
||||
"passed": 5,
|
||||
"failed": 0
|
||||
},
|
||||
"validation_results": {
|
||||

```
|
||||
|
||||
**Example Usage:**
|
||||
|
||||
```bash
|
||||
# CLI - Register pack with authentication
|
||||
attune action execute core.register_packs \
|
||||

|
||||
--param api_token="$ATTUNE_API_TOKEN"
|
||||
|
||||
# Force registration (replace existing)
|
||||
attune action execute core.register_packs \

||||
--param pack_paths='["/tmp/attune-packs/slack"]' \
|
||||
--param force=true \
|
||||
--param skip_tests=true
|
||||
```
|
||||
|
||||
## Workflow Integration
|
||||
|
||||
These actions are designed to work together in the `core.install_packs` workflow:
|
||||
|
||||
```yaml
|
||||
# Simplified workflow structure
|
||||
workflow:
|
||||
- download_packs:
|
||||
action: core.download_packs
|
||||
input:
|
||||
packs: "{{ parameters.packs }}"
|
||||
destination_dir: "{{ vars.temp_dir }}"
|
||||
|
||||
- get_dependencies:
|
||||
action: core.get_pack_dependencies
|
||||
input:
|
||||
pack_paths: "{{ download_packs.output.downloaded_packs | map('pack_path') }}"
|
||||
|
||||
- build_environments:
|
||||
action: core.build_pack_envs
|
||||
input:
|
||||
pack_paths: "{{ download_packs.output.downloaded_packs | map('pack_path') }}"
|
||||
|
||||
- register_packs:
|
||||
action: core.register_packs
|
||||
input:
|
||||
pack_paths: "{{ download_packs.output.downloaded_packs | map('pack_path') }}"
|
||||
```
|
||||
|
||||
## Error Handling
|
||||
|
||||
All actions follow consistent error handling patterns:
|
||||
|
||||
1. **Validation Errors**: Return errors in the `errors` or `failed_*` arrays
|
||||
2. **Partial Failures**: Process continues for other packs; failures are reported
|
||||
3. **Fatal Errors**: Exit with non-zero code and minimal JSON output
|
||||
4. **Timeouts**: Commands respect timeout parameters; failures are recorded
|
||||
|
||||
Example error output:
|
||||
|
||||
```json
|
||||
{
|
||||
"downloaded_packs": [],
|
||||
"failed_packs": [
|
||||
{
|
||||
"source": "https://github.com/invalid/repo.git",
|
||||
"error": "Git clone failed or timed out"
|
||||
}
|
||||
],
|
||||
"total_count": 1,
|
||||
"success_count": 0,
|
||||
"failure_count": 1
|
||||
}
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
Comprehensive test suite available at:
|
||||
```
|
||||
packs/core/tests/test_pack_installation_actions.sh
|
||||
```
|
||||
|
||||
Run tests:
|
||||
```bash
|
||||
cd packs/core/tests
|
||||
./test_pack_installation_actions.sh
|
||||
```
|
||||
|
||||
Test coverage includes:
|
||||
- Input validation
|
||||
- JSON output format validation
|
||||
- Error handling (invalid paths, missing files)
|
||||
- Edge cases (spaces in paths, missing version fields)
|
||||
- Timeout handling
|
||||
- API integration (with mocked endpoints)
|
||||
|
||||
## Implementation Details
|
||||
|
||||
### Directory Structure
|
||||
|
||||
```
|
||||
packs/core/actions/
|
||||
├── download_packs.sh # Implementation
|
||||
├── download_packs.yaml # Schema
|
||||
├── get_pack_dependencies.sh
|
||||
├── get_pack_dependencies.yaml
|
||||
├── build_pack_envs.sh
|
||||
├── build_pack_envs.yaml
|
||||
├── register_packs.sh
|
||||
└── register_packs.yaml
|
||||
```
|
||||
|
||||
### Dependencies
|
||||
|
||||
**System Requirements:**
|
||||
- `bash` 4.0+
|
||||
- `jq` (JSON processing)
|
||||
- `curl` (HTTP requests)
|
||||
- `git` (for git sources)
|
||||
- `tar`, `unzip` (for archive extraction)
|
||||
- `python3`, `pip3` (for Python environments)
|
||||
- `node`, `npm` (for Node.js environments)
|
||||
|
||||
**Optional:**
|
||||
- `md5sum` or `shasum` (checksums)
|
||||
|
||||
### Environment Variables
|
||||
|
||||
Actions receive parameters via environment variables with prefix `ATTUNE_ACTION_`:
|
||||
|
||||
```bash
|
||||
export ATTUNE_ACTION_PACKS='["slack@1.0.0"]'
|
||||
export ATTUNE_ACTION_DESTINATION_DIR=/tmp/packs
|
||||
export ATTUNE_ACTION_API_TOKEN="secret-token"
|
||||
```
|
||||
|
||||
### Output Format
|
||||
|
||||
All actions output JSON to stdout. Stderr is used for logging/debugging.
|
||||
|
||||
```bash
|
||||
# Redirect stderr to see debug logs
|
||||
./download_packs.sh 2>&1 | tee debug.log
|
||||
|
||||
# Parse output
|
||||
output=$(./download_packs.sh 2>/dev/null)
|
||||
success_count=$(echo "$output" | jq '.success_count')
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Use Workflows**: Prefer `core.install_packs` workflow over individual actions
|
||||
2. **Check Dependencies**: Always run `get_pack_dependencies` before installation
|
||||
3. **Handle Timeouts**: Set appropriate timeout values for large packs
|
||||
4. **Validate Output**: Check JSON validity and error fields after execution
|
||||
5. **Clean Temp Directories**: Remove downloaded packs after successful registration
|
||||
6. **Use API Tokens**: Always provide authentication for production environments
|
||||
7. **Enable SSL Verification**: Only disable for testing/development
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Issue: Git clone fails with authentication error
|
||||
|
||||
**Solution**: Use SSH URLs with configured SSH keys or HTTPS with tokens:
|
||||
```bash
|
||||
# SSH (requires key setup)
|
||||
packs='["git@github.com:attune/pack-slack.git"]'
|
||||
|
||||
# HTTPS with token
|
||||
packs='["https://token@github.com/attune/pack-slack.git"]'
|
||||
```
|
||||
|
||||
### Issue: Python virtualenv creation fails
|
||||
|
||||
**Solution**: Ensure Python 3 and venv module are installed:
|
||||
```bash
|
||||
sudo apt-get install python3 python3-venv python3-pip
|
||||
```
|
||||
|
||||
### Issue: Registry lookup fails
|
||||
|
||||
**Solution**: Check registry URL and network connectivity:
|
||||
```bash
|
||||
curl -I https://registry.attune.io/index.json
|
||||
```
|
||||

### Issue: API registration fails with 401 Unauthorized
|
||||
|
||||
**Solution**: Provide valid API token:
|
||||
```bash
|
||||
export ATTUNE_ACTION_API_TOKEN="$(attune auth token)"
|
||||
```
|
||||
|
||||
### Issue: Timeout during npm install
|
||||
|
||||
**Solution**: Increase timeout parameter:
|
||||
```bash
|
||||
--param timeout=1200 # 20 minutes
|
||||
```

### Action Implementation
|
||||
|
||||
Action implementations receive parameters as environment variables prefixed with `ATTUNE_ACTION_`.
|
||||
Actions receive parameters according to the `parameter_delivery` method specified in their metadata:
|
||||
|
||||
**Shell Example (`actions/echo.sh`):**
|
||||
- **`env`** (default): Parameters as environment variables prefixed with `ATTUNE_ACTION_`
|
||||
- **`stdin`**: Parameters via standard input in the specified format
|
||||
- **`file`**: Parameters in a temporary file (path in `ATTUNE_PARAMETER_FILE` env var)
|
||||
|
||||
**Security Warning**: Environment variables are visible in process listings. Use `stdin` or `file` for sensitive data.

# Execute Action Modal: Environment Variables
|
||||
|
||||
**Feature:** Custom Environment Variables for Manual Executions
|
||||
**Added:** 2026-02-07
|
||||
**Location:** Actions Page → Execute Action Modal
|
||||
|
||||
## Overview
|
||||
|
||||
The Execute Action modal now includes an "Environment Variables" section that allows users to specify optional runtime configuration for manual action executions. This is useful for debug flags, log levels, and other runtime settings.
|
||||
|
||||
## UI Components
|
||||
|
||||
### Modal Layout
|
||||
|
||||
```
|
||||
┌──────────────────────────────────────────────────────────┐
|
||||
│ Execute Action X │
|
||||
├──────────────────────────────────────────────────────────┤
|
||||
│ │
|
||||
│ Action: core.http_request │
|
||||
│ Make an HTTP request to a specified URL │
|
||||
│ │
|
||||

|
||||
├──────────────────────────────────────────────────────────┤
|
||||

|
||||
│ │
|
||||
├──────────────────────────────────────────────────────────┤
|
||||
│ [Cancel] [Execute] │
|
||||
└──────────────────────────────────────────────────────────┘
|
||||
```
|
||||
|
||||
## Features
|
||||
|
||||
### Dynamic Key-Value Rows
|
||||
|
||||
Each environment variable is entered as a key-value pair on a separate row:
|
||||
|
||||
- **Key Input:** Text field for the environment variable name (e.g., `DEBUG`, `LOG_LEVEL`)
|
||||
- **Value Input:** Text field for the environment variable value (e.g., `true`, `debug`)
|
||||
- **Remove Button:** X icon to remove the row (disabled when only one row remains)
|
||||
|
||||
### Add/Remove Functionality
|
||||
|
||||
- **Add:** Click "+ Add Environment Variable" to add a new empty row
|
||||
- **Remove:** Click the X button on any row to remove it
|
||||
- **Minimum:** At least one row is always present (remove button disabled on last row)
|
||||
- **Empty Rows:** Rows with blank keys are filtered out when submitting
|
||||
|
||||
### Validation
|
||||
|
||||
- No built-in validation (flexible for debugging)
|
||||
- Empty key rows are ignored
|
||||
- Key-value pairs are sent as-is to the API
|
||||
|
||||
## Use Cases
|
||||
|
||||
### 1. Debug Mode
|
||||
```
|
||||
Key: DEBUG
|
||||
Value: true
|
||||
```
|
||||
Action script can check `if [ "$DEBUG" = "true" ]; then set -x; fi`
|
||||
|
||||
### 2. Custom Log Level
|
||||
```
|
||||
Key: LOG_LEVEL
|
||||
Value: debug
|
||||
```
|
||||
Action script can use `LOG_LEVEL="${LOG_LEVEL:-info}"`
|
||||
|
||||
### 3. Timeout Override
|
||||
```
|
||||
Key: TIMEOUT_SECONDS
|
||||
Value: 30
|
||||
```
|
||||
Action script can use `TIMEOUT="${TIMEOUT_SECONDS:-60}"`
|
||||
|
||||
### 4. Feature Flags
|
||||
```
|
||||
Key: ENABLE_EXPERIMENTAL
|
||||
Value: true
|
||||
```
|
||||
Action script can conditionally enable features
|
||||
|
||||
### 5. Retry Configuration
|
||||
```
|
||||
Key: MAX_RETRIES
|
||||
Value: 5
|
||||
```
|
||||
Action script can adjust retry behavior
|
||||
|
||||
## Important Distinctions
|
||||
|
||||
### ❌ NOT for Sensitive Data
|
||||
- Environment variables are stored in the database
|
||||
- They appear in execution logs
|
||||
- Use action parameters with `secret: true` for passwords/API keys
|
||||
|
||||
### ❌ NOT for Action Parameters
|
||||
- Action parameters go via stdin as JSON
|
||||
- Environment variables are for runtime configuration only
|
||||
- Don't duplicate action parameters here
|
||||
|
||||
### ✅ FOR Runtime Configuration
|
||||
- Debug flags and feature toggles
|
||||
- Log levels and verbosity settings
|
||||
- Timeout and retry overrides
|
||||
- Non-sensitive execution metadata
|
||||
|
||||
## Example Workflow
|
||||
|
||||
### Step 1: Open Execute Modal
|
||||
1. Navigate to Actions page
|
||||
2. Find desired action
|
||||
3. Click "Execute" button
|
||||
|
||||
### Step 2: Fill Parameters
|
||||
Fill in required and optional action parameters as usual.
|
||||
|
||||
### Step 3: Add Environment Variables
|
||||
1. Scroll to "Environment Variables" section
|
||||
2. Enter first env var (e.g., `DEBUG` = `true`)
|
||||
3. Click "+ Add Environment Variable" to add more rows
|
||||
4. Enter additional env vars (e.g., `LOG_LEVEL` = `debug`)
|
||||
5. Click X to remove any unwanted rows
|
||||
|
||||
### Step 4: Execute
|
||||
Click "Execute" button. The execution will have:
|
||||
- Action parameters delivered via stdin (JSON)
|
||||
- Environment variables set in the process environment
|
||||
- Standard Attune env vars (`ATTUNE_ACTION`, `ATTUNE_EXEC_ID`, etc.)
|
||||
|
||||
## API Request Example
|
||||
|
||||
When you click Execute with environment variables, the UI sends:
|
||||
|
||||
```json
|
||||
POST /api/v1/executions/execute
|
||||
{
|
||||
"action_ref": "core.http_request",
|
||||
"parameters": {
|
||||
"url": "https://api.example.com",
|
||||
"method": "GET"
|
||||
},
|
||||
"env_vars": {
|
||||
"DEBUG": "true",
|
||||
"LOG_LEVEL": "debug",
|
||||
"TIMEOUT_SECONDS": "30"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Action Script Usage
|
||||
|
||||
In your action script, environment variables are available as standard environment variables:
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
|
||||
# Check custom env vars
|
||||
if [ "$DEBUG" = "true" ]; then
|
||||
set -x # Enable debug mode
|
||||
echo "Debug mode enabled" >&2
|
||||
fi
|
||||
|
||||
# Use custom log level
|
||||
LOG_LEVEL="${LOG_LEVEL:-info}"
|
||||
echo "Log level: $LOG_LEVEL" >&2
|
||||
|
||||
# Apply custom timeout
|
||||
TIMEOUT="${TIMEOUT_SECONDS:-60}"
|
||||
echo "Using timeout: ${TIMEOUT}s" >&2
|
||||
|
||||
# Read action parameters from stdin
|
||||
INPUT=$(cat)
|
||||
URL=$(echo "$INPUT" | jq -r '.url')
|
||||
|
||||
# Execute action logic
|
||||
curl --max-time "$TIMEOUT" "$URL"
|
||||
```
|
||||
|
||||
## Tips & Best Practices
|
||||
|
||||
### 1. Use Uppercase for Keys
|
||||
Follow Unix convention: `DEBUG`, `LOG_LEVEL`, not `debug`, `log_level`
|
||||
|
||||
### 2. Provide Defaults in Scripts
|
||||
```bash
|
||||
DEBUG="${DEBUG:-false}"
|
||||
LOG_LEVEL="${LOG_LEVEL:-info}"
|
||||
```
|
||||
|
||||
### 3. Document Common Env Vars
|
||||
Add comments in your action YAML:
|
||||
```yaml
|
||||
# Supports environment variables:
|
||||
# - DEBUG: Enable debug mode (true/false)
|
||||
# - LOG_LEVEL: Logging verbosity (debug/info/warn/error)
|
||||
# - TIMEOUT_SECONDS: Request timeout in seconds
|
||||
```
|
||||
|
||||
### 4. Don't Duplicate Parameters
|
||||
If an action has a `timeout` parameter, use that instead of `TIMEOUT_SECONDS` env var.
|
||||
|
||||
### 5. Test Locally First
|
||||
Test with env vars set locally before using in production:
|
||||
```bash
|
||||
DEBUG=true LOG_LEVEL=debug ./my_action.sh < params.json
|
||||
```
