# ── GoClaw Agent Container ────────────────────────────────────────────────────
#
# Autonomous agent microservice that:
#  1. Exposes a lightweight HTTP API (port 8080) for receiving tasks
#  2. Has access to the Swarm overlay network (goclaw-net)
#  3. Connects to the shared MySQL database for persistence
#  4. Calls the LLM API via the GoClaw Gateway
#  5. Auto-registers itself with the orchestrator on startup
#
# Build: docker build -f docker/Dockerfile.agent -t goclaw-agent:latest .
# Deploy: docker service create --name goclaw-agent-NAME \
#           --network goclaw-net \
#           -e AGENT_ID=NAME \
#           -e GATEWAY_URL=http://goclaw-gateway:18789 \
#           -e DATABASE_URL=mysql://... \
