Chart Releaser (Private) Action

GitHub Action inspired by the official Chart Releaser Action by Helm, to make a Helm Chart repository (public) out of a private one, on GitHub.

Motivation

This aims to fix the official action's limitations; specifically, the fact that you can't upload packages nor update/push the index.yaml to a repository which is not the one where the action is running on.

Private repositories releases need authentication to be accessed, which makes it harder to use with chart releaser. Another fact is that private repositories cannot use GitHub Pages unless on a paid tier.

This creates an issue for those with a private repository, that's why the idea/strategy that this action takes is:

1. Use the action on a private repository, which contains the charts.
2. Upload chart packages and deploy the index.yaml to a separate, public repository, which does not contain the charts' source code (otherwise it defeats the point of this action).

Pre-requisites

1. A private GitHub repository (public untested) that contains helm charts source code under a directory (e.g. /charts)
2. A public GitHub repository where the Helm Chart packages and index.yaml will be uploaded/deployed to

Usage

On the private repo:

name: Release Charts

on:
  push:
    branches:
      - main

jobs:
  release:
    runs-on: ubuntu-latest

        uses: actions/checkout@v2
        with:
          fetch-depth: 0

      - name: Install Helm
        uses: azure/setup-helm@v1
