release-please-manifest-action

Opinionated action for running release-please in manifest mode.

A composite action which wraps release-please-action and github-app-token actions, with opinionated default settings focused on running release-please in manifest mode.

Note: This is a fork of jimeh/release-please-manifest-action, customized by @krystal for their own needs. Upstream changes will be included as appropriate.

Features

• Focuses on and only supports running release-please's manifest command.
• Optionally supports having release-please authenticate as a GitHub App.
• Defaults to looking for release-please's config and manifest files within the top-level .github directory instead of in the repository root.

Examples

All examples assume you have placed your release-please-config.json and .release-please-manifest.json within the .github directory in the root of the repository.

See release-please's manifest-releaser documentation for details about the config and manifest files.

Basic (Actions Token)

This example will have release-please authenticate using secrets.GITHUB_TOKEN that is automatically available to all actions.

This will prevent checks / GitHub Actions running against any Release Pull Requests raised by release-please. This is a feature of GitHub as a means of trying to avoid GitHub Actions jobs triggering themselves, causing an endless loop.

If you need checks to run against Release Pull Requests, you will need to have release-please authenticate with a Personal Access Token (PAT), or as a GitHub App.

on: push
jobs:
  release-please:
    runs-on: ubuntu-latest
    if: github.ref == 'refs/heads/main'
    steps:
      - uses: krystal/release-please-manifest-action@v1

The above is equivalent to:

on: push
jobs:
  release-please:
    runs-on: ubuntu-latest
    if: github.ref == 'refs/heads/main'
    steps:
      - uses: google-github-actions/release-please-action@v3
        id: release-please
        with:
          command: manifest
          config-file: .github/release-please-config.json
          manifest-file: .github/.release-please-manifest.json

Note: Outputs are not included in this equivalence example.

Personal Access Token (PAT) Authentication

This example will have release-please authenticate with a user's Personal Access Token (PAT), performing all operations on behalf of that user. Allowing checks / GitHub Actions to run against Release Pull Requests.

It is common to have a dedicated "bot" user created for these purposes. But within paid organizations, that means an extra user seat needs to be paid for. In that case you might prefer using a GitHub App instead.

on: push
jobs:
  release-please:
    runs-on: ubuntu-latest
    if: github.ref == 'refs/heads/main'
    steps:
      - uses: krystal/release-please-manifest-action@v1
        with:
          token: ${{ secrets.RELEASE_PAT_TOKEN }}

The above is equivalent to:

on: push
jobs:
  release-please:
    runs-on: ubuntu-latest
    if: github.ref == 'refs/heads/main'
    steps:
      - uses: google-github-actions/release-please-action@v3
        id: release-please
        with:
          token: ${{ secrets.RELEASE_PAT_TOKEN }}
          command: manifest
          config-file: .github/release-please-config.json
          manifest-file: .github/.release-please-manifest.json

Note: Outputs are not included in this equivalence example.

GitHub App Authentication

This example will have release-please authenticate as a GitHub App, performing all operations on behalf of the app.

This has a few benefits compared to using the token provided by GitHub Actions or a user's personal access token:

• It allows checks / GitHub Actions to run against the Release Pull Requests raised by release-please.
• An app can be given permissions to access all repos within an organization.
• Compared to creating a separate "bot" user, paid organizations do not need to pay for an extra user seat when using an app.

Below we assume you have already setup RELEASE_BOT_APP_ID and RELEASE_BOT_PRIVATE_KEY secrets in the repository or organization.

To set the private key secret, it is easiest to base64 encode the contents of the *.pem file you get from the GitHub App's configuration page. The base64 encoded string should not have any line-breaks.

on: push
jobs:
  release-please:
    runs-on: ubuntu-latest
    if: github.ref == 'refs/heads/main'
    steps:
      - uses: krystal/release-please-manifest-action@v1
        with:
          app-id: ${{ secrets.RELEASE_BOT_APP_ID }}
          private-key: ${{ secrets.RELEASE_BOT_PRIVATE_KEY }}

The above is equivalent to:

on: push
jobs:
  release-please:
    runs-on: ubuntu-latest
    if: github.ref == 'refs/heads/main'
    steps:
      - uses: tibdex/github-app-token@v1
        id: github-app-token
        with:
          app_id: ${{ secrets.RELEASE_BOT_APP_ID }}
          private_key: ${{ secrets.RELEASE_BOT_PRIVATE_KEY }}
      - uses: google-github-actions/release-please-action@v3
        id: release-please
        with:
          token: ${{ steps.github-app-token.outputs.token }}
          command: manifest
          config-file: .github/release-please-config.json
          manifest-file: .github/.release-please-manifest.json

Note: Outputs are not included in this equivalence example.
