1. Automating Dataset Updates Notification via GitHub Webhooks


    To automate dataset updates notification via GitHub webhooks you can use the github.RepositoryWebhook resource from the GitHub provider for Pulumi. This allows setting up a webhook on a GitHub repository that triggers notifications (to an HTTP URL) on certain events such as a push to the repository which could indicate updates to datasets if they are stored within the repo.

    Here's the breakdown of the steps we're going to take in the program:

    1. Import the required Pulumi packages.
    2. Create a new GitHub repository webhook.
    3. Configure the webhook to listen to push events (or any other events that signify dataset updates).
    4. Point the webhook to an HTTP URL that will handle the notification -- this could be a service or an automation server that processes the data updates.

    It's assumed that you already have a GitHub repository where your dataset is stored, and an HTTP server or service ready to receive the webhook notifications.

    Below is a Pulumi program that will set up such a webhook:

    import pulumi import pulumi_github as github # It's assumed you have a GitHub personal access token set in your environment variables # or Pulumi configuration. If not, you'll need to do something like this: # pulumi.Config('github').get('token') # Replace 'my-repo' with the name of your GitHub repository and 'my-owner' with the # owner of the repository, which could either be a user or an organization. repo_name = "my-repo" repo_owner = "my-owner" # The URL to which the webhook will send events. This should be your server or service # that processes the dataset updates. target_url = "https://your-webhook-receiver.service.com/handle-updates" # Creating a new GitHub repository webhook. repo_webhook = github.RepositoryWebhook("dataset-update-webhook", repository=repo_name, active=True, events=["push"], configuration=dict( url=target_url, content_type="json", )) # To get the ID of the webhook - which can be useful for debug purposes, # we export it as a stack output. pulumi.export("webhook_id", repo_webhook.id)

    In this program:

    • We use the github.RepositoryWebhook resource to create a new webhook.
    • We set repository to the name of our repo, events to listen for push events, and configuration to specify the webhook's target URL and content type.
    • Finally, we export the id of the webhook so it can be easily retrieved later, for example, if we need to troubleshoot the webhook.

    Make sure you have the correct permissions to the GitHub repository as well as the pulumi_github package installed in your Python environment. The server that receives the webhook should already be configured to handle the incoming data as per your operational requirements.

    After running the program with Pulumi CLI, the webhook will be created in your GitHub repository. To see the effect, any push to the repository will trigger a notification to the target_url, where you can process the update accordingly.
