Pushing and pulling images in GCP - Mini Project: Build & Apply

Pushing and Pulling Container Images on Google Cloud

📖 Scenario: You are working on a cloud project where you need to store and retrieve container images using Google Cloud's Container Registry. This helps you manage your application images securely and deploy them easily.

🎯 Goal: Learn how to tag a local Docker image, push it to Google Container Registry, and pull it back from the registry.

📋 What You'll Learn

Create a variable with the local Docker image name

Create a variable with the Google Cloud project ID

Tag the local image with the Google Container Registry path

Push the tagged image to Google Container Registry

💡 Why This Matters

🌍 Real World

Developers and DevOps engineers often push container images to cloud registries to share and deploy applications easily.

💼 Career

Knowing how to manage container images in Google Cloud is essential for cloud engineers, developers, and DevOps professionals working with containerized applications.

1

Set local Docker image name

Create a variable called local_image and set it to the string "myapp:latest" representing your local Docker image name.

GCP

# Create a variable called local_image with value "myapp:latest"
# Your code here

Need a hint?

Use a simple assignment statement to create the variable.

2

Set Google Cloud project ID

Create a variable called project_id and set it to the string "my-gcp-project" representing your Google Cloud project ID.

GCP

local_image = "myapp:latest"
# Create a variable called project_id with value "my-gcp-project"
# Your code here

Need a hint?

Use a simple assignment statement to create the variable.

3

Tag the local image for Google Container Registry

Create a variable called tagged_image that combines "gcr.io/", the project_id, and the local_image separated by slashes, to form the full image path for Google Container Registry.

GCP

local_image = "myapp:latest"
project_id = "my-gcp-project"
# Create tagged_image combining "gcr.io/", project_id, and local_image
# Your code here

Need a hint?

Use an f-string to combine the parts into a full image path.

4

Push the tagged image to Google Container Registry

Write the Docker commands to tag the local image with tagged_image and then push the tagged_image to Google Container Registry. Use the exact commands: docker tag {local_image} {tagged_image} and docker push {tagged_image}.

GCP

local_image = "myapp:latest"
project_id = "my-gcp-project"
tagged_image = f"gcr.io/{project_id}/{local_image}"
# Tag the local image with tagged_image
# Push the tagged_image to Google Container Registry
# Your code here

Need a hint?

Use the exact Docker commands with the variables to tag and push the image.
