Publishing to Pypi

Poetry's documentation

Note that it is recommended to use API tokens when uploading packages to PyPI.

Once you have created a new token, you can tell Poetry to use it:

https://python-poetry.org/docs/repositories/#configuring-credentials

We do this using GitHub Actions' Workflows and Repository Secrets!

Repo Secrets

Go to your repo settings and add a PYPI_TOKEN environment variable:

Inspect the GitHub Actions Publish Workflows

name: Publish

on:
  release:
    types:
      - created

jobs:
  publish:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      ...
      ...
      ...
      - name: Publish
        env:
          PYPI_TOKEN: ${{ secrets.PYPI_TOKEN }}
        run: |
          poetry config pypi-token.pypi $PYPI_TOKEN
          bash scripts/publish.sh

That's it!

When you make a release on GitHub, the publish workflow will run and deploy to PyPi! 🚀🎉😎
