How Do I Set Permissions for Google Container Registry and Google Cloud Run?

Introduction

Setting up permissions for Google Container Registry (GCR) and Google Cloud Run is a critical step for securely managing and deploying your applications in Google Cloud. Proper configuration ensures that only authorized users and services can access and manage your resources, thus maintaining the integrity and security of your cloud infrastructure.

Step-by-Step Guide to Setting Permissions

To configure permissions for GCR and Cloud Run, you need to set up specific Identity and Access Management (IAM) roles. This process involves creating a service account and binding it to the necessary roles that allow it to interact with GCR and Cloud Run resources.

Steps:

1. Define the Google Cloud Project: Specify the project where your resources will be deployed.

2. Create a Service Account: Generate a service account that will be granted permissions to manage GCR and Cloud Run.

3. Bind IAM Roles: Assign the required IAM roles to the service account:

   • roles/storage.objectViewer: Allows viewing and pulling images from GCR.
   • roles/storage.objectAdmin: Grants permissions to manage objects in GCR.
   • roles/run.admin: Provides full management permissions for Cloud Run services.
   • roles/iam.serviceAccountUser: Permits the service account to act as a Cloud Run service.

Below is the complete TypeScript example for setting up these permissions:

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

// Define a Google Cloud project
const myProject = new gcp.organizations.Project("my_project", {
    name: "My Project",
    projectId: "my-gcp-project",
    orgId: "your-organization-id",
});
// Create a service account for interacting with GCR and Cloud Run
const gcrCloudrunSa = new gcp.serviceaccount.Account("gcr_cloudrun_sa", {
    accountId: "gcr-cloudrun-sa",
    displayName: "Service Account for GCR and Cloud Run",
});
// Assign required IAM roles for GCR and Cloud Run to the service account
const gcrViewerBinding = new gcp.projects.IAMBinding("gcr_viewer_binding", {
    project: myProject.projectId,
    role: "roles/storage.objectViewer",
    members: [pulumi.interpolate`serviceAccount:${gcrCloudrunSa.email}`],
});
const gcrAdminBinding = new gcp.projects.IAMBinding("gcr_admin_binding", {
    project: myProject.projectId,
    role: "roles/storage.objectAdmin",
    members: [pulumi.interpolate`serviceAccount:${gcrCloudrunSa.email}`],
});
const cloudRunAdminBinding = new gcp.projects.IAMBinding("cloud_run_admin_binding", {
    project: myProject.projectId,
    role: "roles/run.admin",
    members: [pulumi.interpolate`serviceAccount:${gcrCloudrunSa.email}`],
});
const serviceAccountUserBinding = new gcp.projects.IAMBinding("service_account_user_binding", {
    project: myProject.projectId,
    role: "roles/iam.serviceAccountUser",
    members: [pulumi.interpolate`serviceAccount:${gcrCloudrunSa.email}`],
});

Key Points

• Service Account: Central to managing permissions, enabling secure interactions with GCR and Cloud Run.
• IAM Roles: Essential for defining what actions the service account can perform.
• Security: Proper setup ensures that only authorized entities can access your cloud resources.

Conclusion

Configuring permissions for Google Container Registry and Google Cloud Run is an essential task for maintaining a secure and efficient cloud environment. By following the steps outlined above, you ensure that your service account has the appropriate access to manage and deploy resources securely. This setup not only helps in maintaining operational integrity but also fortifies your cloud infrastructure against unauthorized access.
