Triggering AI Test Suites on Code Commits with GitHub Webhooks

Question

Pulumi · Accepted Answer

To trigger AI test suites on code commits, you can utilize webhooks provided by GitHub. A webhook is an HTTP callback that occurs when something happens; a simple event-notification via HTTP POST. When integrated with GitHub, it can trigger custom workflows (like your AI test suites) on events such as `push`, `pull_request`, or other GitHub activities.

In this context, we'll set up a GitHub webhook that triggers whenever code is committed to a repository. We'll use Pulumi with the `pulumi_github` provider to provision this webhook. This webhook will need to notify an external service (e.g., CI/CD pipeline, server, lambda function) where the AI test suites are configured to run. For this example, I'm going to assume you have a server or a service that can receive HTTP POST requests and process them to run your AI test suites, referred to as `your_ai_test_suite_service_url`.

Below is a Pulumi program in Python that creates a GitHub repository webhook for this purpose. Make sure you replace `your_repo_name`, `your_github_organization`, and `your_ai_test_suite_service_url` with your specific details.

```python
import pulumi
import pulumi_github as github

# Replace these variables with your own details
repo_name = "your_repo_name"  # Your GitHub repository name
org_name = "your_github_organization"  # Your GitHub organization or username
ai_test_suite_service_url = "your_ai_test_suite_service_url"  # URL for the service that runs your AI test suites

# Create a GitHub repository webhook
repo_webhook = github.RepositoryWebhook("test_suite_webhook",
    repository=repo_name,
    configuration=github.RepositoryWebhookConfigurationArgs(
        url=ai_test_suite_service_url,  # The service that receives the webhook to trigger the test suite
        content_type="json",
        secret="your_secret",  # A secret to validate received webhook payloads. This should be generated and managed securely.
        insecure_ssl=False,
    ),
    events=["push"],  # List of events to trigger the webhook, in this case, a push event to the repository
    active=True,
)

# Export the webhook URL so you can see it in the Pulumi output
pulumi.export("webhook_url", repo_webhook.configuration.apply(lambda conf: conf.url))
```

### Explanation:

- **pulumi_github**: This is the Pulumi provider for interacting with GitHub. You use this provider to manage resources like repositories, actions, and webhooks on GitHub.
- **RepositoryWebhook**: This resource type is used to create and manage a webhook on a GitHub repository.
- **RepositoryWebhookConfigurationArgs**: Configuration arguments for the webhook, including the URL which is called by GitHub when the specified event occurs.
- **events**: Specifies the GitHub events that will trigger the webhook. In this example, the webhook is triggered when code is pushed to the repository (`"push"` event).
- **pulumi.export**: This outputs the webhook's target URL after the Pulumi program is run. It's useful for confirming that the webhook was set up correctly.

Please remember to replace placeholders with actual values and keep your webhook's `secret` safe and secure. Also, the service receiving the webhook (specified at `your_ai_test_suite_service_url`) should be prepared to validate the secret and handle incoming webhook payloads appropriately to trigger the AI test suites.
