1. Setting Permissions for Google Cloud Functions in AI Pipelines


    To set permissions for Google Cloud Functions, you can use IAM policies and bindings. These allow you to define who (which members) have what access (which roles) to a specific Google Cloud Function. This is crucial in AI pipelines when various functions may be invoked by different services or users, and tight control over permissions is necessary to ensure security and proper access.

    In Pulumi, the Google Cloud provider offers resources such as FunctionIamPolicy, FunctionIamBinding, and FunctionIamMember, which correspond to different levels of granularity in setting IAM permissions:

    • FunctionIamPolicy: Sets the entire IAM policy for the function.
    • FunctionIamBinding: Adds a single binding to the IAM policy of the function, which associates one or more members with a single role.
    • FunctionIamMember: Adds a single member to a specific role in the IAM policy of the function.

    Choosing between these depends on whether you need to set the entire policy at once, add specific roles with members, or add individual members to roles.

    Below is a Pulumi program in Python that demonstrates how to use these resources to set permissions for a Google Cloud Function in an AI pipeline. The example assumes you've already deployed a Google Cloud Function and now need to set the permissions.

    import pulumi import pulumi_gcp as gcp # Replace the following placeholders with your actual values: project_id = "your-gcp-project-id" cloud_function_name = "your-cloud-function-name" region = "your-function-region" # An example of FunctionIamPolicy resource that sets the entire IAM policy for the function. # This replaces the entire policy. function_iam_policy = gcp.cloudfunctions.FunctionIamPolicy("function-iam-policy", project=project_id, region=region, cloud_function=cloud_function_name, bindings=[ gcp.cloudfunctions.FunctionIamPolicyBindingArgs( role="roles/cloudfunctions.invoker", # The role that should be applied members=["serviceAccount:your-invoker-service-account@gcp-sa-pubsub.iam.gserviceaccount.com"], # Members to which this policy should apply ), ]) # An example of FunctionIamBinding resource that adds a single binding to the IAM policy. # This allows adding a new role binding without disturbing others. function_iam_binding = gcp.cloudfunctions.FunctionIamBinding("function-iam-binding", project=project_id, region=region, cloud_function=cloud_function_name, role="roles/cloudfunctions.developer", # The role to be added members=[ "user:some-user@example.com", # List the users who should have this role ]) # An example of FunctionIamMember resource that adds a single member with a specific role to the IAM policy. # This is useful for adding individual permissions one at a time. function_iam_member = gcp.cloudfunctions.FunctionIamMember("function-iam-member", project=project_id, region=region, cloud_function=cloud_function_name, role="roles/cloudfunctions.viewer", # The role assigned to the member member="user:some-other-user@example.com", # Member to be added to the role condition=gcp.cloudfunctions.FunctionIamMemberConditionArgs( title="title-for-condition", expression="expression-for-condition", )) # Exports the URLs pointing to the Google Cloud Function so they can be used elsewhere pulumi.export("invoker-url", function_iam_binding.id.apply(lambda _: f"https://{region}-{project_id}.cloudfunctions.net/{cloud_function_name}")) pulumi.export("developer-url", function_iam_member.id.apply(lambda _: f"https://{region}-{project_id}.cloudfunctions.net/{cloud_function_name}"))

    This program sets up three different IAM controls for a Cloud Function:

    • Sets a policy that allows a service account to invoke the Cloud Function.
    • Adds a binding to the Cloud Function's IAM policy that grants developer access to a specific user.
    • Adds a single viewer member to the Cloud Function's IAM policy with an optional condition.

    Be sure to replace the placeholders like your-gcp-project-id, your-cloud-function-name, your-function-region, and email addresses with the appropriate values for your specific setup. The condition within the FunctionIamMember is optional and can be used for more granular control based on certain criteria. If you don't need it, you can remove that argument.

    Pulumi will manage the state of these IAM policies and bindings for your Google Cloud Functions ensuring that access control changes are correctly applied in your AI pipeline infrastructure.
