ArgoCD App Version Action

This GitHub Action connects to ArgoCD using the ArgoCD API (no CLI or Node.js required) to retrieve the list of applications and their respective versions running in your cluster. It then updates the README file in your Git repository with this information.

Getting Started

1. Create ArgoCD API Token
   Generate an API token in ArgoCD and add it as a GitHub secret (e.g., ARGOCD_TOKEN).
   Also add your ArgoCD server URL as a secret (e.g., ARGOCD_SERVER).

2. Reference the Action in Your Workflow
   Use the action in your workflow as shown below.

Usage

To use this action, include it in your GitHub workflow file. Here is an example of how to set it up:

name: Update README with ArgoCD App Versions

on:
  push:
    branches:
      - main

jobs:
  update-readme:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout repository
        uses: actions/checkout@v2

      - name: Update README with ArgoCD app versions
        uses: ./argocd-app-version-action
        with:
          argocd_server: ${{ secrets.ARGOCD_SERVER }}
          argocd_token: ${{ secrets.ARGOCD_TOKEN }}

      - name: Commit and push changes
        run: |
          git config --local user.email "action@github.com"
