Google Cloud Container Registry Tutorial

Introduction

Google Cloud Container Registry is a private container image registry that runs on Google Cloud Platform. It allows you to store, manage, and secure your Docker container images. This tutorial will guide you through the process of using Google Cloud Container Registry from start to finish.

Prerequisites

Before you begin, you will need the following:

  • A Google Cloud Platform (GCP) account.
  • Google Cloud SDK installed on your local machine.
  • Docker installed on your local machine.

Step 1: Set Up Google Cloud SDK

First, you need to install the Google Cloud SDK. Follow the instructions on the official Google Cloud SDK page to install it.

gcloud init

This command initializes the SDK and allows you to log in to your Google Cloud account and set up your configuration.

Step 2: Enable Container Registry API

Next, you need to enable the Container Registry API for your project:

gcloud services enable containerregistry.googleapis.com

Step 3: Configure Docker to Use Google Cloud Container Registry

Configure Docker to authenticate with Google Cloud Container Registry:

gcloud auth configure-docker

This command configures Docker to use the gcloud authentication system when pushing and pulling images from Google Container Registry.

Step 4: Tag and Push Your Docker Image

Now you can tag and push your Docker image to Google Container Registry. Assume you have a Docker image named my-app:

docker tag my-app gcr.io/[PROJECT-ID]/my-app

docker push gcr.io/[PROJECT-ID]/my-app

Replace [PROJECT-ID] with your actual GCP project ID.

Step 5: Pull Your Docker Image

To pull the Docker image from Google Container Registry, you can use the following command:

docker pull gcr.io/[PROJECT-ID]/my-app

Step 6: Manage Your Docker Images

You can manage your container images using the Google Cloud Console or the gcloud command-line tool. To list all images in your registry, use:

gcloud container images list

This command lists all the Docker images in your Container Registry.

Conclusion

In this tutorial, you have learned how to set up and use Google Cloud Container Registry to store and manage your Docker images. This powerful tool integrates seamlessly with Google Cloud, providing a secure and efficient way to handle your containerized applications.
