How do I configure a GCP container registry?

To configure Google Cloud’s Container Registry, you need to set up the necessary resources within your Google Cloud Platform project. This includes enabling the Container Registry API and creating a storage bucket to hold your images. Here’s how you do it:

1. Enable the Container Registry API: You’ll need to enable the Container Registry API for your project, which allows you to interact with the Container Registry service.
2. Storage Bucket: The Container Registry uses Google Cloud Storage buckets to store images. These buckets need to be in a specific format suitable for the registry.

Below is a sample Terraform program that highlights these steps:

import * as pulumi from "@pulumi/pulumi";
import * as gcp from "@pulumi/gcp";

// Enable the Container Registry API
const containerRegistryApi = new gcp.projects.Service("container_registry_api", {service: "containerregistry.googleapis.com"});
// Create a storage bucket for the Container Registry
const containerRegistryBucket = new gcp.storage.Bucket("container_registry_bucket", {
    name: "my-container-registry",
    location: "US",
});
// Set IAM policy on the bucket to allow Container Registry to use it
const containerRegistryPermissions = new gcp.storage.BucketIAMMember("container_registry_permissions", {
    bucket: containerRegistryBucket.name,
    role: "roles/storage.objectAdmin",
    member: "serviceAccount:container-registry@google.com",
});
export const containerRegistryBucketName = containerRegistryBucket.name;
export const containerRegistryApiStatus = containerRegistryApi.service;

In this example:

• We specify the Google Cloud project and region.
• We enable the containerregistry.googleapis.com API for the project to ensure we can interact with the Container Registry.
• We create a storage bucket my-container-registry which is used to store container images.
• We set IAM policies to allow Container Registry to access the bucket.

Run this program to set up the necessary infrastructure for using Google Cloud’s Container Registry in your project.

In summary, we configured the Google Cloud Container Registry by enabling the appropriate API, creating a storage bucket for storing images, and setting the necessary IAM policies. This sets up a basic infrastructure you can build upon for managing container images in Google Cloud.
