Python

Initialise a Python project:

$ creo -i python

This creates pyproject.toml, src/<name>/main.py, src/<name>/__init__.py, and a fiat file.

Defaults

Property	Value
`bin=`	`src` — source directory (used for OCI directory layering)
`cmd=`	`$UV sync --frozen`
`sources=`	`*.py pyproject.toml setup.py setup.cfg`

The src directory is used directly as the application root in OCI images. If you need a different source layout, set bin= explicitly.

Variable	Default
`$UV`	`uv`
`$PYTHON`	`python3`

Python projects use directory-based OCI layering — the entire src/ tree is added to the image at /app/:

image: oci
    require=build
    repo=ghcr.io/myorg/myapp
    from=python:3.11-slim
    entrypoint=python3 /app/main.py
