11.1. Configure the GitHub Events Module plugin

Configure GitHub webhooks to trigger real-time updates for GitHub Discovery and organizational data.

Learn how to configure Events Module for use with the RHDH GitHub Discovery feature and GitHub organization data.

Prerequisites

  • You have added your GitHub integration credentials in the app-config.yaml file.
  • You have defined the schedule.frequency in the app-config.yaml file as longer time period, such as 24 hours.
  • For GitHub Discovery only: You have enabled GitHub Discovery.
  • For GitHub Organizational Data only: You have enabled Github Authentication with user ingestion.

Procedure

  1. Add the GitHub Events Module to your dynamic-plugins.yaml configuration file as follows:

    data:
    dynamic-plugins.yaml: |
    includes:
    - dynamic-plugins.default.yaml
    plugins:
    - package: oci://registry.access.redhat.com/rhdh/backstage-plugin-events-backend-module-github@sha256:2c1ccc4fb01883dc4da1aa0c417d6e28d944c6ce941454ee41698f2c1812035c
    disabled: false
  2. To create HTTP endpoints to receive events for the github, add the following to your app-config.yaml file:

    events:
      http:
       topics:
        - github
      modules:
        github:
          webhookSecret: ${GITHUB_WEBHOOK_SECRET}
    Important

    Secure your workflow by adding a webhook secret token to validate webhook deliveries.

  3. Create a GitHub webhook with the following specifications:

    • For GitHub Discovery Events: push, repository
    • For GitHub Organizational Data Events: organization, team and membership
    • Content Type: application/json
    • Payload URL: https://<my_developer_hub_domain>/api/events/http/github

      Note

      Payload URL is the URL exposed after configuring the HTTP endpoint.

Verification

  • Check the log for an entry that confirms that http endpoint was set up successfully to receive events from the GitHub webhook.

    Example of a log of successfully set up http endpoint
    {"level":"\u001b[32minfo\u001b[39m","message":"Registered /api/events/http/github to receive events","plugin":"events","service":"backstage","timestamp":"2025-11-03 02:19:12"}
  • For GitHub Discovery only:

    • Trigger a GitHub push event by adding, modifying or deleting the catalog-info.yaml file in the repository where you set up your webhook. A record of this event should appear in the pod logs of your RHDH instance.

      Example of a log with changes to catalog-info.yaml file
      {"level":"\u001b[32minfo\u001b[39m","message":"Processed Github push event: added 0 - removed 0 - modified 1","plugin":"catalog","service":"backstage","span_id":"47534b96c4afc654","target":"github-provider:providerId","timestamp":"2025-06-15 21:33:14","trace_flags":"01","trace_id":"ecc782deb86aed2027da0ae6b1999e5c"}
  • For GitHub Organizational Data only:

    • Newly added users and teams appear in the RHDH catalog.
