Help to deploy only some versions

[kennylajara]

I want to be able to upload my packages to pypi when I create a release. But I don't want to do it on every release, just stable versions. I read your tip:

Pro tip: instead of using branch pointers, like master, pin versions of Actions that you use to tagged versions or sha1 commit identifiers. This will make your workflows more secure and better reproducible, saving you from sudden and unpleasant surprises.

But I couldn't make it work.

I tried with the if you suggested but I couldn't deploy any package (tagged or not) when I added the if. This one:

 if: github.event_name == 'push' && startsWith(github.ref, 'refs/tags')

Could you help me to implement that. This is my current pypi-publish.yml:

# This workflow will upload a Python Package using Twine when a release is created
# For more information see: https://help.github.com/en/actions/language-and-framework-guides/using-python-with-github-actions#publishing-to-package-registries

# This workflow uses actions that are not certified by GitHub.
# They are provided by a third-party and are governed by
# separate terms of service, privacy policy, and support
# documentation.

name: Upload to PyPI

  release:
    branches: [ main ]

    steps:

    - name: Install dependencies
      run: |
        python -m pip install --upgrade pip
        pip install build

For this, create a separate step, analyze your version with Python, and set an output (see https://docs.github.com/en/actions/reference/workflow-commands-for-github-actions#setting-an-output-parameter). Then, use that output in an if-clause later.

Here's an example job that runs before all the others, for inspiration: https://github.com/ansible/pylibssh/blob/45d2199/.github/workflows/build-test-n-publish.yml#L32-L148.

P.S. re: "I tried with the if you suggested but I couldn't deploy any package (tagged or not) when I added the if. This one" — this is because your clause expected the event to be push but your workflow only gets triggered on release so the conditional is never true.
