chart-releaser Action

A GitHub action to turn a GitHub project into a self-hosted Helm chart repo, using helm/chart-releaser CLI tool.

Usage

Pre-requisites

1. A GitHub repo containing a directory with your Helm charts (eg: /charts)
2. A GitHub project Secret named CR_TOKEN with the value of a GitHub personal access token
   • The token must have repo scope
   • The token's user must have write access to the project
   • To mitigate risk you may wish to limit the token to a single project by creating a machine user
   • Please note the personal access token is required because of an Actions bug, and will hopefully be unnecessary in the future
3. Create a workflow .yml file in your .github/workflows directory. An example workflow is available below. For more information, reference the GitHub Help Documentation for Creating a workflow file

Inputs

For more information on inputs, see the API Documentation

• version: The chart-releaser version to use (default: v1.0.0-beta.1)
• charts_dir: The charts directory
• charts_repo_url: The GitHub Pages URL to the charts repo (default: https://<owner>.github.io/<project>)

Example Workflow

Create a workflow (eg: .github/workflows/release.yml):

name: Release Charts

on:
  push:
    branches:
      - master

jobs:
  release:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v1

      - name: Configure Git
        run: |
          git config user.name "$GITHUB_ACTOR"
          git config user.email "[email protected]"

      - name: Run chart-releaser
        uses: helm/[email protected]
        env:
          CR_TOKEN: "${{ secrets.CR_TOKEN }}"

This uses @helm/chart-releaser-action to turn your GitHub project into a self-hosted Helm chart repo. It does this – during every push to master – by checking each chart in your project, and whenever there's a new chart version, creates a corresponding GitHub release named for the chart version, adds Helm chart artifacts to the release, and creates or updates an index.yaml file with metadata about those releases, which is then hosted on GitHub Pages
