# docker-compose.yml — production-ready reference for dolphin-mcp-pilot
#
# Quick start:
#   cp .env.example .env        # edit with your DolphinScheduler credentials
#   docker compose up -d
#
# Development (local Dockerfile + read-only source mount):
#   docker compose down
#   docker compose --profile dev up -d dolphin-mcp-pilot-dev
#
# The prod service (dolphin-mcp-pilot) pulls from ghcr.io by default.
# The dev service (dolphin-mcp-pilot-dev) builds from source and mounts
# ./dolphin_mcp_pilot read-only. Source changes require a container restart
# (uvicorn is not started with --reload). They share config via YAML
# anchors (x-common).
#
# Port convention: the container always listens on 8001 internally (matching
# the Dockerfile HEALTHCHECK). The MCP_PORT variable controls the host-side
# port mapping only.
