ah-annotation

GitHub Action to generate ArtifactHub annotations from Git commit history and add them to Chart.yaml.

The action parses conventional commit messages between two Git tags and produces an artifacthub.io/changes annotation. Pre-release tags (matching -rc) are detected automatically and result in an artifacthub.io/prerelease annotation instead.

Usage

Auto-detect tags

Without explicit inputs the action determines the two most recent non-RC tags from the Git history:

steps:
  - uses: actions/checkout@v7.0.1
    with:
      fetch-depth: 0
  - uses: volker.raschek/ah-annotations@v0.1.2

Explicit tags

Pass old-tag and new-tag to control the commit range:

steps:
  - uses: actions/checkout@v7.0.1
    with:
      fetch-depth: 0
  - uses: volker.raschek/ah-annotations@v0.1.2
    with:
      old-tag: v1.0.0
      new-tag: v2.0.0

Inputs

Name	Required	Default	Description
chart-path	no	${{ github.workspace }}/Chart.yaml	Path to the Helm chart file.
old-tag	no	auto-detected	Start tag for changelog generation.
new-tag	no	auto-detected	End tag for changelog generation.
yq-version	no	v4.44.6	Version of yq to install.
yq-arch	no	auto-detected	Architecture of yq binary to download.
yq-os	no	auto-detected	Operating system of yq binary to download.
yq-binary-name	no	yq	Name of the yq binary to download.
yq-download-url	no	auto-built	Full URL to download yq from.

Requirements

• The repository must be checked out with full history (fetch-depth: 0).
• A Chart.yaml file must exist at the path specified by chart-path.
• Commit messages must follow the Conventional Commits format.

Pre-releases

Tags matching the pattern -rc (e.g. v1.0.0-rc.1, v2.0.0-rc) are treated as pre-releases. When new-tag is a pre-release tag, the action:

1. Sets artifacthub.io/prerelease: "true" in Chart.yaml.
2. Skips changelog generation entirely.

When auto-detecting tags (no explicit old-tag/new-tag), the action ignores pre-release tags and selects the two most recent stable tags instead.
