Example

Simple

- uses: convictional/[email protected]
  with:
    owner: keithconvictional
    repo: myrepo
    github_token: ${{ secrets.GITHUB_PERSONAL_ACCESS_TOKEN }}

All Options

- uses: convictional/[email protected]
  with:
    owner: keithconvictional
    repo: myrepo
    github_token: ${{ secrets.GITHUB_PERSONAL_ACCESS_TOKEN }}
    github_user: github-user
    workflow_file_name: main.yml
    ref: release-branch
    wait_interval: 10
    client_payload: '{}'
    propagate_failure: false
    trigger_workflow: true
    wait_workflow: true

Comment the current running workflow URL for a PR

- uses: convictional/[email protected]
  with:
    owner: keithconvictional
    repo: myrepo
    github_token: ${{ secrets.GITHUB_PERSONAL_ACCESS_TOKEN }}
    comment_downstream_url: ${{ github.event.pull_request.comments_url }}

Testing

You can test out the action locally by cloning the repository to your computer. You can run:

INPUT_OWNER="keithconvictional" \
INPUT_REPO="myrepo" \
INPUT_GITHUB_TOKEN="<REDACTED>" \
INPUT_GITHUB_USER="github-user" \
INPUT_WORKFLOW_FILE_NAME="main.yml" \
INPUT_REF="release-branch" \
INPUT_WAIT_INTERVAL=10 \
INPUT_CLIENT_PAYLOAD='{}' \
INPUT_PROPAGATE_FAILURE=false \
INPUT_TRIGGER_WORKFLOW=true \
INPUT_WAIT_WORKFLOW=true \
busybox sh entrypoint.sh

You will have to create a Github Personal access token. You can create a test workflow to be executed. In a repository, add a new main.yml to .github/workflows/. The workflow will be:

name: Main
on:
  workflow_dispatch
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@master
      - name: Pause for 25 seconds
        run: |
          sleep 25

You can see the example here. For testing a failure case, just add this line after the sleep:

...
- name: Pause for 25 seconds
  run: |
    sleep 25
    echo "For testing failure"
    exit 1
