# ── Timmy Time — agent image ────────────────────────────────────────────────
#
# Serves two purposes:
#   1. `make docker-up`    → runs the FastAPI dashboard (default CMD)
#   2. `make docker-agent` → runs a swarm agent worker (override CMD)
#
# Build:  docker build -t timmy-time:latest .
# Dash:   docker run -p 8000:8000 -v $(pwd)/data:/app/data timmy-time:latest
# Agent:  docker run -e COORDINATOR_URL=http://dashboard:8000 \
#                    -e AGENT_NAME=Worker-1 \
#                    timmy-time:latest \
#                    python -m swarm.agent_runner --agent-id w1 --name Worker-1
