Why container registry matters in GCP - See It in Action

Why Container Registry Matters

📖 Scenario: You are working on a team that builds and deploys applications using containers. Your team needs a safe and easy place to store container images so they can be used later for deployment.

🎯 Goal: Build a simple container registry setup on Google Cloud Platform (GCP) to understand why storing container images in a registry is important for deployment and collaboration.

📋 What You'll Learn

Create a variable to hold the container image name

Add a configuration variable for the registry location

Write a command to tag the container image with the registry path

Write a command to push the container image to the registry

💡 Why This Matters

🌍 Real World

Teams use container registries to store and share container images safely and reliably before deploying applications.

💼 Career

Understanding container registries is essential for cloud engineers and developers working with containerized applications and continuous deployment pipelines.

1

Create the container image name variable

Create a variable called image_name and set it to the exact string myapp:v1.

GCP

# Create a variable called image_name and set it to 'myapp:v1'
# Your code here

Need a hint?

Use simple assignment to create the variable.

2

Add the registry location configuration

Create a variable called registry_location and set it to the exact string us-central1.

GCP

image_name = 'myapp:v1'
# Create a variable called registry_location and set it to 'us-central1'
# Your code here

Need a hint?

This variable will help specify where the container registry is located.

3

Tag the container image with the registry path

Write a command that creates a new variable called tagged_image which combines the registry path gcr.io/my-project/ with the image_name variable using an f-string.

GCP

image_name = 'myapp:v1'
registry_location = 'us-central1'
# Create tagged_image combining 'gcr.io/my-project/' and image_name using an f-string
# Your code here

Need a hint?

Use an f-string to combine the registry path and image name.

4

Push the container image to the registry

Write a command that assigns a string to a variable called push_command with the exact value docker push {tagged_image} using an f-string.

GCP

image_name = 'myapp:v1'
registry_location = 'us-central1'
tagged_image = f'gcr.io/my-project/{image_name}'
# Create push_command string 'docker push {tagged_image}' using an f-string
# Your code here

Need a hint?

This command simulates pushing the image to the container registry.
