Resolving Azure Pipelines CI Not Firing After Migration to GitHub Enterprise

When organizations transition from using personal GitHub accounts to GitHub Enterprise Managed Users, several processes may be disrupted. One common issue that can arise is Azure Pipelines' Continuous Integration (CI) not triggering automatically. This can lead to confusion, especially if manual builds continue to work without a hitch. In this guide, we'll explore how to diagnose and fix this issue effectively.

Understanding the Issue

After migrating repository management to GitHub Enterprise, you may find that Azure DevOps CI pipelines no longer fire automatically. Users reported being able to run builds manually but noticed that the automation aspect had stopped functioning. A few things you can check include:

GitHub Settings: The changes in repository settings may affect webhooks.

Webhooks: A common source of CI issues stems from improperly configured webhooks, especially if secrets and tokens were not correctly carried over during migration.

Step-by-Step Solution

Here's a step-by-step guide that can help you fix the issue and restore your CI pipeline's functionality:

Step 1: Check GitHub Repository Settings

Navigate to Your GitHub Repository: Start by accessing the specific repository you're having issues with.

Open Repository Settings: On the right side of your repository page, click on "Settings".

Access Webhooks: Scroll down to the Webhooks section in the left sidebar.

Step 2: Review Existing Webhooks

Identify Errors: When you check the webhook associated with Azure Pipelines, look for any errors. Issues might have occurred due to migrations that did not migrate important configurations such as secrets.

Verify Configuration: Ensure that the webhook is correctly set to point to Azure DevOps and that the authentication token (if applicable) is still valid.

Step 3: Resolve Configuration Issues

If you identified errors related to the webhook configuration:

Delete the Problematic Webhook: If any errors are found, delete the existing webhook.

Restore the Connection: Return to Azure DevOps. Within your pipeline settings, you should see an option to add or restore the webhook connection.

Test the Setup: Trigger a commit in the repository to verify if the pipeline now reacts accordingly.

Additional Tips

Create Personal Access Tokens: If issues persist, ensure that the necessary personal access tokens are created and have appropriate scopes.

Consult Documentation: Review both Azure DevOps and GitHub documentation for updated configurations and troubleshooting guides specific to your settings.

Community Support: If after these steps CI is still not functioning, consider reaching out to community forums and user groups; they can provide valuable insights from their experiences.

Conclusion

Migrating to GitHub Enterprise can sometimes result in unexpected hiccups, such as Azure Pipelines CI failing to trigger. The issue often lies in misconfigured webhooks that fail to connect due to incorrect secrets or tokens. By carefully reviewing your GitHub repository settings and re-establishing the webhook for Azure DevOps, you should be able to restore the automation that is crucial for a seamless development workflow.

Follow these steps, and you'll be back on track with your CI pipelines running smoothly once again!
