PyPI publish GitHub Action

This action allows you to upload your Python distribution packages in the dist/ directory to PyPI. This text suggests a minimalistic usage overview. For more detailed walkthrough check out the PyPA guide.

Usage

To use the action add the following step to your workflow file (e.g. .github/workflows/main.yml)

- name: Publish a Python distribution to PyPI
  uses: pypa/gh-action-pypi-publish@master
  with:
    user: __token__
    password: ${{ secrets.pypi_password }}

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.

A common use case is to upload packages only on a tagged commit, to do so add a filter to the step:

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

So the full step would look like:

- name: Publish package
  if: github.event_name == 'push' && startsWith(github.ref, 'refs/tags')
  uses: pypa/gh-action-pypi-publish@master
  with:
    user: __token__
    password: ${{ secrets.pypi_password }}

The example above uses the new API token feature of PyPI, which is recommended to restrict the access the action has.

The secret used in ${{ secrets.pypi_password }} needs to be created on the settings page of your project on GitHub. See Creating & using secrets.

Non-goals

This GitHub Action has nothing to do with building package distributions. Users are responsible for preparing dists for upload by putting them into the dist/ folder prior to running this Action.

Advanced release management

For best results, figure out what kind of workflow fits your project's specific needs.

For example, you could implement a parallel workflow that pushes every commit to TestPyPI or your own index server, like devpi. For this, you'd need to (1) specify a custom repository_url value and (2) generate a unique version number for each upload so that they'd not create a conflict. The latter is possible if you use setuptools_scm package but you could also invent your own solution based on the distance to the latest tagged commit.

You'll need to create another token for a separate host and then save it as a GitHub repo secret.

The action invocation in this case would look like:

- name: Publish package to TestPyPI
  uses: pypa/gh-action-pypi-publish@master
  with:
    user: __token__
    password: ${{ secrets.test_pypi_password }}
    repository_url: https://test.pypi.org/legacy/

Customizing target package dists directory

You can change the default target directory of dist/ to any directory of your liking. The action invocation would now look like:

- name: Publish package to PyPI
  uses: pypa/gh-action-pypi-publish@master
  with:
    user: __token__
    password: ${{ secrets.pypi_password }}
    packages_dir: custom-dir/

Disabling metadata verification

It is recommended that you run twine check just after producing your files, but this also runs twine check before upload. You can also disable the twine check with:

   with:
     verify_metadata: false
