This action allows you to organize CI/CD with GitHub Actions and werf.

Ready-to-use GitHub Actions Workflows for different CI/CD workflows are available here.

How to use

converge:
  name: Converge
  runs-on: ubuntu-latest
  steps:

    - name: Checkout code
      uses: actions/checkout@v4
      with:
        fetch-depth: 0

    - name: Install werf
      uses: werf/actions/install@v2

    - name: Run script
      run: |
        . $(werf ci-env github --as-file) 
        werf converge
      env:
        WERF_KUBECONFIG_BASE64: ${{ secrets.KUBE_CONFIG_BASE64_DATA }}
        WERF_ENV: production

Versioning

When using action, select the version corresponding to the required MAJOR version of werf.

By default, the action installs actual werf version within alpha channel (more details about channels, werf release cycle and compatibility promise here). Using the channel input the user can switch the release channel.

This is recommended approach to be up-to-date and to use actual werf version without changing configurations.

- uses: werf/actions/install@v2
  with:
    channel: alpha

Withal, it is not necessary to work within release channels, and the user might specify certain werf version with version input.

- uses: werf/actions/install@v2
  with:
    version: v2.1.0

FAQ

werf always rebuilds images on new commit

Make sure to use fetch-depth: 0 setting in the checkout action, like follows:

- name: Checkout code
  uses: actions/checkout@v4
  with:
    fetch-depth: 0

By default, fetch-depth set to 1 which disables git history when checking out code. werf cache selection algorithm uses git history to determine whether some image bound to some commit could be used as a cache when building current commit (current commit should be descendant to the cache commit).

Setting fetch-depth to 0 enables full fetch of git history, and it is a recommended approach. It is also possible to limit fetch history with some decent number of commits, which would enable images caching limited to that number of commits, but this would have a negative impact on cache reproducibility.
