install-pinned/pdm

Securely install the latest pdm release from PyPI.

This action installs a pinned version of pdm 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 pdm from PyPI
        uses: install-pinned/pdm@b077fe8e69ca0d16f3485b14d8593abf63e3d99e  # 2.28.1

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!
