Development

During development, the container installs Node.js and nodemon to enable automatic reloads when files change. The development server is started with:

nodemon --delay 1 --watch pyproject.toml --watch ".venv/lib/*" --watch ".venv/lib64/*" --exec "uv run --isolated uvicorn src.main:app --host 0.0.0.0 --port 8000 --reload --reload-dir src --reload-exclude \".venv/**\""

This will:

  • Use nodemon to watch for changes to pyproject.toml and restart the server when changes are detected.
  • Run the command uv run —isolated uvicorn src.main:app —host 0.0.0.0 —port 8000 —reload in an isolated Python environment.
  • Start the FastAPI app using uvicorn on all network interfaces at port 8000.
  • Enable hot-reload via uvicorn —reload, so the server automatically restarts when Python source files change.

Production

Builds a production-ready image. During the build, dependencies are installed with uv sync. When the container starts, it runs:

fastapi run src/main.py --proxy-headers --port 8000

This uses the FastAPI CLI to serve your application on port 8000.
