Multi-stage Dockerfile (python:3.11-slim, non-root, /health healthcheck) with an entrypoint that applies alembic migrations before uvicorn, a compose file pairing the API with Postgres 16, and a CI workflow that builds multi-arch images and pushes branch/semver/sha/latest tags to ghcr.io. PR builds compile the image without pushing.
