1. Controlling access to GCP Storage Buckets with IAM Conditions

    TypeScript

    To control access to GCP Storage Buckets with IAM conditions, you would utilize the gcp.storage.Bucket resource to create a storage bucket and the gcp.storage.BucketAccessControl resource to set the IAM policy on the bucket with conditions.

    Here's a detailed step-by-step explanation of how you can set this up using Pulumi with TypeScript:

    1. Import the necessary packages: Begin by importing the required GCP package.
    2. Create a storage bucket: Provision a new Google Cloud Storage bucket using the gcp.storage.Bucket resource.
    3. Define access control: Apply the IAM conditions to control access using the gcp.storage.BucketAccessControl resource.

    Below is the TypeScript program that demonstrates these steps:

    import * as gcp from "@pulumi/gcp"; // Create a new Google Cloud Storage bucket const bucket = new gcp.storage.Bucket("my-bucket", { location: "US", // Specify the location for your bucket }); // Define IAM conditions, here, as an example, we give read-access to the bucket // for a specific user under a specified condition. const bucketReadAccess = new gcp.storage.BucketAccessControl("readAccess", { bucket: bucket.name, // References the newly created bucket role: "READER", // Sets the role to 'READER' for read access entity: "user-12345@example.com", // Define the user who gets the access // You can define conditions such as the request IP and request time here }); // Export the bucket URL export const bucketUrl = bucket.url;

    In this program:

    • We're using the gcp.storage.Bucket resource to create a new bucket named "my-bucket" in the US location. Its URL is then exported as bucketUrl for easy access.
    • We're also using the gcp.storage.BucketAccessControl resource to manage access.
      • bucket: Passes the name of the created bucket.
      • role: Assigns the role of 'READER', which means read access.
      • entity: Specifies the entity (user or group) which we are giving access.

    Please note, this code demonstrates granting READER role to a user without conditions. If you require more complex conditions, you would need to use Cloud IAM policies with conditions. This can involve setting up an IAM policy and defining bindings with conditional expressions. Keep in mind that IAM conditions are a more advanced feature that allows you to specify granular access control.

    For actual IAM conditions, you will likely need to interface directly with the google.cloud.storage.Bucket.IamPolicy resource, or use the Google Cloud Console or gcloud command-line tool, as at the time of writing, Pulumi does not support bucket-level IAM conditions natively.

    For further information and to get more details about the properties and options you can specify, check the Pulumi documentation:

    You would use this code in a Pulumi program, and once executed with pulumi up, it will provision the resources as specified. To run this program, ensure you've got Pulumi CLI installed, access to a GCP project, and the necessary credentials configured.
