1. Version Control for Model Development with GCP Source Repositories


    Version control is a crucial aspect of software development, including model development, as it allows teams to track changes, collaborate effectively, and maintain a history of their work. Google Cloud Platform (GCP) offers Cloud Source Repositories, a fully-featured, scalable, private Git repository service.

    You can use Pulumi to programmatically manage your GCP Source Repositories. In this case, we'll use the pulumi_gcp package that provides a productive and powerful way to create and manage GCP resources. We'll create a new GCP Source Repository for model development.

    First, I'll explain the necessary Pulumi components and their purpose:

    • Stack: A Pulumi stack is an isolated, independently configurable instance of a Pulumi program. Stack corresponds to a deployment environment like production, staging, or testing.

    • Project: Every Pulumi program is contained in a project. A project consists of a Pulumi.yaml file that contains the name and runtime of the project.

    • Resources: In Pulumi, resources are components of your infrastructure, like a compute instance or a storage bucket.

    Below, you will find a Pulumi program written in Python which demonstrates how to create a GCP Source Repository using Pulumi.

    Before you begin, you need to have Pulumi installed and configured for use with GCP:

    1. Install Pulumi: Follow the instructions at Install Pulumi.
    2. Set up GCP configuration: Follow the steps at GCP Configuration.

    Once you have Pulumi installed and configured to interact with GCP, here's the code to create a new Source Repository:

    import pulumi import pulumi_gcp as gcp # Initialize a new GCP project and a source repository for our model development class GcpModelDevSourceRepo(pulumi.ComponentResource): def __init__(self, name: str, opts: pulumi.ResourceOptions = None): super().__init__('custom:resource:GcpModelDevSourceRepo', name, {}, opts) # Create a GCP Cloud Source Repository for storing model development version history self.repo = gcp.sourcerepo.Repository(name, name=name, opts=pulumi.ResourceOptions(parent=self)) # Export the URL of the created repository which you can use to clone and push code pulumi.export('repository_url', self.repo.url) # Create a new GCP Source Repository resource called 'model-dev-repo' model_dev_repo = GcpModelDevSourceRepo('model-dev-repo') # Export the repository URL as a stack output pulumi.export('model_dev_repo_url', model_dev_repo.repo.url)


    • We define a Pulumi component resource GcpModelDevSourceRepo that encapsulates the logic for creating a GCP source repository.
    • Inside the component, we create a sourcerepo.Repository resource which corresponds to the source repository in GCP.
    • The pulumi.export statements are used to output the repository URL after the Pulumi program runs, which you can use to access your repository in the GCP Console or through the Git CLI.

    Run the Pulumi program with pulumi up in your command line, and it will provision the GCP source repository. After it is created, the model_dev_repo_url stack output will contain the URL of the new repository.

    This program registers a single Git repository for your model development project in GCP, which you can clone and use just like any other Git repository. This helps establish a foundation for managing versions of your models or any associated code.
