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 branch called gh-pages to store the published charts. See charts_repo_url for alternatives
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

• version: The chart-releaser version to use (default: v1.2.1)
• config: Optional config file for chart-releaser. For more information on the config file, see the documentation
• charts_dir: The charts directory
• charts_repo_url: The GitHub Pages URL to the charts repo (default: https://<owner>.github.io/<project>)

Environment variables

• CR_TOKEN (required): The GitHub token of this repository (${{ secrets.GITHUB_TOKEN }})

For more information on environment variables, see the documentation.

Example Workflow

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

name: Release Charts

on:
  push:
    branches:
      - main

jobs:
  release:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v2
        with:
          fetch-depth: 0

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

      - name: Install Helm
        uses: azure/setup-helm@v1
        with:
          version: v3.4.0

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

Example using custom config

workflow.yml:

- name: Run chart-releaser
  uses: helm/[email protected]
  with:
    charts_dir: charts
    config: cr.yaml
    charts_repo_url: xxxxxx
  env:
    CR_TOKEN: "${{ secrets.GITHUB_TOKEN }}"

cr.yaml:

owner: myaccount
git-base-url: https://api.github.com/

For options see config-file.
