Github action that pushes a notification to PagerDuty on a Pull Request

Here is an example of how you would setup the action in your own repository under .github/workflows/notifier.yml.

name: Notify PagerDuty on Pull Request
on: [pull_request]
jobs:
  pd_notify:
    name: notification
    runs-on: ubuntu-latest
    steps:
      - name: pagerduty-notifier
        id: pd-notifier
        uses: lmasaya/pagerduty-notifier-action@v1
        env:
          PAGERDUTY_API_TOKEN: ${{ secrets.PAGERDUTY_API_TOKEN }}
          PAGERDUTY_ROUTING_KEY: ${{ secrets.PAGERDUTY_ROUTING_KEY }}
          PAGERDUTY_SEVERITY: 'warning'
          PAGERDUTY_SOURCE: ${{ github.repository }}
          PAGERDUTY_SOURCE_URL: ${{ github.event.pull_request.html_url }}
          PAGERDUTY_SUMMARY: ${{ github.actor }} created Pull Request on ${{ github.repository }}

You must pass the following environment variables to generate the alert. All fields are required for now.

You should store the PAGERDUTY_API_TOKEN and PAGERDUTY_ROUTING_KEY as secrets of your repository or organization. See Github documentation on creating and storing secrets.

Instead of building the Dockerfile in the Github Action repository, the action runs a pre-built docker container built with the Dockerfile. You are welcome to fork and have the action build the container on run, but this will make running the action slower.
