PagerDuty Alert GitHub Action

Sends a critical PagerDuty alert, e.g. on action failure. Optionally, resolves on success.

Prerequisites

1. Create a service integration in PagerDuty:
   1. Go to PagerDuty > "Services" > Pick your service > "Integrations" > "Add a new integration";
   2. Choose a name (e.g. "Your GitHub CI/CD") and "Use our API directly" with "Events API v2";
   3. Copy the integration key.
2. Set up a secret in your GitHub repo to store the integration key, e.g. "PAGERDUTY_INTEGRATION_KEY".

Inputs

pagerduty-integration-key

Required: the integration key for your PagerDuty service. See instructions above for how to obtain.

pagerduty-dedup-key

Optional: a dedup_key for your alert. This will enable PagerDuty to coalesce multiple alerts into one.\ Default: None

runbook-url

Optional: A URL to a runbook for the alert. This will be included in the alert. Useful for providing instructions on how to troubleshoot/resolve the issue. \ Default: None

resolve

Optional: If set to true, will resolve any active alerts with the dedup_key. This allows you to automatically resolve active alerts for a job once it succeeds. Requires a separate step in your GitHub Actions process; see below. \ Default: false

More documentation on the above parameters is available here.

Example usage

Adding this to your steps will send a PagerDuty alert if the job fails. It is recommended to add this step at the end of your job to cover all possible failures.

- name: Send PagerDuty alert on failure
  if: ${{ failure() }}
  uses: Entle/action-pagerduty-alert@1.0.2
  with:
    pagerduty-integration-key: '${{ secrets.PAGERDUTY_INTEGRATION_KEY }}'
    pagerduty-dedup-key: github_workflow_failed
    runbook-url: 'https://example.com/runbook'

Optionally, add the below step after the one above to resolve the alert if a subsequent job succeeds.

- name: Resolve PagerDuty alert on success
  if: ${{ !failure() }}
  uses: Entle/action-pagerduty-alert@1.0.2
  with:
    pagerduty-integration-key: '${{ secrets.PAGERDUTY_INTEGRATION_KEY }}'
    pagerduty-dedup-key: github_workflow_failed
    resolve: true

Adding both steps to your job will create an alert when the job fails, and resolve the alert when the job succeeds. Using ${{ github.workflow }} for pagerduty-dedup-key (or any other key that is unique per-workflow) allows multiple jobs that each trigger and resolve alerts independently, while customizing the logic within the if configs allows for more complex page and resolution behavior.
