release-notifier-action

GitHub Action to notify repositories about the repository's releases using a GitHub App

Important: if the release event was created by another GitHub action authenticated with secrets.GITHUB_TOKEN, no workflow is triggered for that release event. To workaround that problem, use a personal access token instead of secrets.GITHUB_TOKEN to create the release event. See Triggering new workflows using a personal access token.

Setup

In order to use the action, you have to register a GitHub app.

• GitHub App name: set to something like <Your Project> Release Notifier
• Description: copy/paste most of this repository's Notifier app. Make sure to replace release-notifier-release with <your-project>-release
• Homepage URL: your repository URL
• Webhook: remove the check from [ ] Active
• Repository permissions: Enable Read & Write access for Contents
• Where can this GitHub App be installed?: Any account (unless you only want installs for repositories with in your account/organization)

Once you are done, generate & download a private key. In your repository, create to secrets:

1. APP_ID: set to your newly registered App ID
2. APP_PRIVATE_KEY: set to the contents of the downloaded *.pem file

Usage

Notify repositories only when a release was published. The repository dispatch event type is set to [current repositories full name] release (e.g. gr2m/release-notifier-action release)

name: Release Notification
on:
  release:
    types:
      - published

jobs:
  notify:
    runs-on: ubuntu-latest
    steps:
      - uses: gr2m/release-notifier-action@v1
        with:
          app_id: ${{ secrets.APP_ID }}
          private_key: ${{ secrets.APP_PRIVATE_KEY }}

If you want to notify repositories for all release activity types, you can do

name: Release Notification
on: release

jobs:
  notify:
    runs-on: ubuntu-latest
    steps:
      - uses: gr2m/release-notifier-action@v1
        with:
          app_id: ${{ secrets.APP_ID }}
          private_key: ${{ secrets.APP_PRIVATE_KEY }}

To customize the repository dispatch event type use the dispatch_event_type argument

name: Release Notification
on:
  release:
    types:
      - published

jobs:
  notify:
    runs-on: ubuntu-latest
    steps:
      - uses: gr2m/release-notifier-action@v1
        with:
          app_id: ${{ secrets.APP_ID }}
          private_key: ${{ secrets.APP_PRIVATE_KEY }}
          dispatch_event_type: my-project-release

How it works

Each time you create, edit, or delete a release on your repository, the action will load all installations using the credentials you provided. For each installation, the action dispatch creates a repository dispatch event and sets the event type to what you configured in inputs.dispatchEventType.
