# Agent-Based Worker Services
#
# This override file demonstrates how to add custom runtime workers to Attune
# by injecting the universal worker agent into any container image.
#
# Usage:
#   docker compose -f docker-compose.yaml -f docker-compose.agent.yaml up -d
#
# Prerequisites:
#   The init-agent service (defined in docker-compose.yaml) must be present.
#   It builds the statically-linked agent binary and populates the agent_bin volume.
#
# How it works:
#   1. init-agent builds a musl-static attune-agent binary and copies it to the agent_bin volume
#   2. Each worker service mounts agent_bin read-only and uses the agent as its entrypoint
#   3. The agent auto-detects available runtimes in the container (python, ruby, node, etc.)
#   4. No Dockerfile needed — just point at any container image with your desired runtime
#
# Adding your own worker:
#   Copy one of the examples below and change:
#   - service name (e.g., worker-my-runtime)
#   - image (any Docker image with your runtime installed)
#   - ATTUNE_WORKER_NAME (unique name for this worker)
#   - Optionally set ATTUNE_WORKER_RUNTIMES to override auto-detection
