This GitHub Action generates manifests for Helm charts and kustomize overlays, allowing for easier deployment and management of Kubernetes applications. It integrates with Helm and dynamically adds Helm repositories based on the charts and overlays found in the specified source folder. The generated manifests are then templated and committed to the specified destination branch.

The action expects a specific directory structure in the source_folder. Here's an example:

source_folder
  myapp
    base
      Chart.yaml
      kustomization.yaml
      values.yaml
    overlays
      cluster1
        kustomization.yaml
        my-patch.yaml
        values.yaml
      cluster2
        kustomization.yaml
        values.yaml

In this structure, myapp is a Helm chart with a base configuration and two overlays, cluster1 and cluster2. Each overlay can have its own values.yaml file and additional kustomize patches.

The folder containing the Helm charts and kustomize overlays. This input is required. The default value is dev.

The branch to commit the changes to. This input is not required. The default value is the current branch of the head commit.

The version of Helm to use. This input is not required. The default value is 'v3.14.4'.

Here's an example of how to use this action in a workflow:

name: Generate Kustomized Helm Manifests

on:
  push:
    branches:
      - main

jobs:
  generate_manifests:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout code
        uses: actions/checkout@v2

      - name: Generate manifests
        uses: your-github-username/kustomized-helm-action@v1
        with:
          source_folder: 'dev'
          destination_branch: 'manifests'
          helm_version: 'v3.14.4'

In this example, the action will generate manifests for the Helm charts and kustomize overlays in the dev directory, and commit the changes to the manifests branch. It will use Helm version v3.14.4.
