A GitHub Action for automatically updating version information in Helm Chart.yaml files.

This action simplifies the process of updating version numbers in Helm chart files during your CI/CD workflow. It automatically updates both the version and appVersion fields in your Chart.yaml file with a single command.

• Updates both version and appVersion fields
• Preserves the original file structure
• Provides detailed logging of changes
• Customizable commit messages
• Flexible path configuration

Add the following step to your GitHub workflow:

- name: Update Helm Chart version
  uses: solairen/helm-chart-updater@main
  with:
    token: ${{ secrets.GITHUB_TOKEN }}
    new_version: '1.2.3'
    # Optional parameters
    chart_path: 'path/to/Chart.yaml'
    commit_message: 'Update chart version to 1.2.3'

name: Update Helm Chart

on:
  release:
    types: [published]

jobs:
  update-chart:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v4

      - name: Update Helm Chart version
        uses: solairen/helm-chart-updater@main
        with:
          token: ${{ secrets.GITHUB_TOKEN }}
          new_version: ${{ github.event.release.tag_name }}

1. The action uses the provided GitHub token to authenticate with your repository
2. It fetches the existing Chart.yaml file from the specified path
3. The version fields are updated with the new version number
4. The updated file is committed back to the repository

• Python 3.x
• Docker (for testing the action locally)

Use the provided development container for a consistent development environment:

# Clone the repository
git clone https://github.com/solairen/helm-chart-updater.git
cd helm-chart-updater

# Use VS Code with Dev Containers extension
# or run the development container directly
docker build -t helm-chart-updater-dev -f docker/Dockerfile-dev .
docker run -it -v $(pwd):/development helm-chart-updater-dev

Test the action locally by setting the required environment variables:

export INPUT_TOKEN="your-github-token"
export INPUT_NEW_VERSION="1.0.0"
export GITHUB_EVENT_PATH="owner/repo"
python update_chart.py
