During development, the container installs Node.js andnodemon 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/*" --watch"src"  --ext"py" --exec"uv run --isolated flask --app src/main.py run --host=0.0.0.0 --port=8000 --no-reload --debug"

This will:

• Activate the virtual environment in.venv
• This runs the Flask app defined in main.py using the uv tool in an isolated environment, making the app available on all network interfaces at port 8000, with debug mode enabled.

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

uv run --frozen gunicorn -w 4 -b 0.0.0.0:8000 src.main:app

This uses the Gunicorn to serve your application on port 8000.
