Github Actions

Create a new release with Github Actions

Automatic bumping of version

To execute cz bump in your CI, and push the new commit and the new tag, back to your master branch, we have to:

  1. Create a personal access token. Follow the instructions here. And copy the generated key
  2. Create a secret called PERSONAL_ACCESS_TOKEN, with the copied key, by going to your project repository and then Settings > Secrets > Add new secret.
  3. In your repository create a new file .github/workflows/bumpversion.yml with the following content.

Warning

If you use GITHUB_TOKEN instead of PERSONAL_ACCESS_TOKEN, the job won't trigger another workflow. It's like using [skip ci] in other CI's.

name: Bump version

on:
  push:
    branches:
      - master

jobs:
  bump-version:
    if: "!startsWith(github.event.head_commit.message, 'bump:')"
    runs-on: ubuntu-latest
    name: "Bump version and create changelog with commitizen"
    steps:
      - name: Check out
        uses: actions/checkout@v2
        with:
          token: "${{ secrets.PERSONAL_ACCESS_TOKEN }}"
          fetch-depth: 0
      - name: Create bump and changelog
        uses: commitizen-tools/commitizen-action@master
        with:
          github_token: ${{ secrets.PERSONAL_ACCESS_TOKEN }}

Push to master and that's it.

Creating a github release

You can modify the previous action.

Add the variable changelog_increment_filename in the commitizen-action, specifying where to output the content of the changelog for the newly created version.

And then add a step using a github action to create the release: softprops/action-gh-release

The commitizen action creates an env variable called REVISION, containing the newely created version.

- name: Create bump and changelog
  uses: commitizen-tools/commitizen-action@master
  with:
    github_token: ${{ secrets.PERSONAL_ACCESS_TOKEN }}
    changelog_increment_filename: body.md
- name: Release
  uses: softprops/action-gh-release@v1
  with:
    body_path: "body.md"
    tag_name: ${{ env.REVISION }}
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Publishing a python package

Once the new tag is created, triggering an automatic publish command would be desired.

In order to do so, the crendetial needs to be added with the information of our PyPI account.

Instead of using username and password, we suggest using api token generated from PyPI.

After generate api token, use the token as the PyPI password and __token__ as the username.

Go to Settings > Secrets > Add new secret and add the secret: PYPI_PASSWORD.

Create a file in .github/workflows/pythonpublish.yaml with the following content:

name: Upload Python Package

on:
  push:
    tags:
      - "*" # Will trigger for every tag, alternative: 'v*'

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v1
      - name: Set up Python
        uses: actions/setup-python@v1
        with:
          python-version: "3.x"
      - name: Install dependencies
        run: |
          python -m pip install --pre -U poetry
          poetry --version
          poetry install
      - name: Build and publish
        env:
          PYPI_USERNAME: __token__
          PYPI_PASSWORD: ${{ secrets.PYPI_PASSWORD }}
        run: |
          ./scripts/publish

Notice that we are calling a bash script in ./scripts/publish, you should configure it with your tools (twine, poetry, etc.). Check commitizen example You can also use pypa/gh-action-pypi-publish to publish your package.

Push the changes and that's it.
