install-pinned/poetry

Securely install the latest poetry release from PyPI.

This action installs a pinned version of poetry and all its dependencies, making sure that file hashes match. Pinning your dependencies:

1. Stops software supply chain attacks.
2. Makes sure your CI does not break unexpectedly.

Usage

In your GitHub Actions workflow, use this action like so:

      - name: Install poetry from PyPI
        uses: install-pinned/poetry@2e4006e6389a5b58ae6d7615c4828f21f2b10555  # 1.8.5

You can set up Dependabot so that your pins are updated regularly.

Alternatives

This action is a relatively simple wrapper around uv and is most useful if there is no existing requirements.txt/uv.lock/... infrastructure in place. If you already pin all your dependencies in a single place, you don't need it!
