Usage

Reusable workflows (and documentation) are located at .github/workflows

Workflows that do not begin with an underscore (e.g. foo.yaml) may be called outside this repository.

Workflows that begin with one underscore (e.g. _foo.yaml) are internal and are only intended to be called by reusable workflows in this repository (that begin with zero or one underscores).

Workflows that begin with two underscores (e.g. __foo.yaml) are for this repository only. They may only be (triggered by an event on this repository or) called by workflows in this repository that begin with two underscores.

Version

Recommendation: pin the latest version (e.g. v1.0.0) and use Renovate to stay up-to-date.

Bug fixes will not be backported.

Example workflow:

jobs:
  build:
    name: Build charms
    uses: canonical/data-platform-workflows/.github/workflows/build_charms_with_cache.yaml@v1.0.0

Example Renovate configuration:

{
  "enabledManagers": ["poetry", "github-actions"],
  "packageRules": [
    // Later rules override earlier rules

    // Group data-platform-workflows Python package & workflow updates into the same PR
    {
      "matchManagers": ["poetry"],
      "matchPackageNames": ["canonical/data-platform-workflows"],
      // Workaround for https://github.com/renovatebot/renovate/discussions/23628
      "versioning": "semver",
      "groupName": "data-platform-workflows",
      // Workaround: data-platform-workflows Python packages use git tags instead of pyproject.toml
      // for versioning. Therefore, Renovate will always think an update is a major version update.
      "separateMajorMinor": false
    },
    {
      "matchManagers": ["github-actions"],
      "matchPackageNames": ["canonical/data-platform-workflows"],
      "groupName": "data-platform-workflows",
      // Workaround: data-platform-workflows Python packages use git tags instead of pyproject.toml
      // for versioning. Therefore, Renovate will always think an update is a major version update.
      // Since we want packages to be updated alongside workflows (actions), we must disable
      // separate major PRs for workflows as well.
      "separateMajorMinor": false
    }
  ]
}

Note: all workflows in this repository share a version number. If a breaking change is made to the public interface of one workflow, all workflows will have a new major version even if they have no breaking changes.

If you do not want to use Renovate, pin to the latest major version (e.g. v1).
