Custom domains in GCP - Mini Project: Build & Apply

Configure a Custom Domain for a Google Cloud Run Service

📖 Scenario: You have deployed a web application on Google Cloud Run. Now, you want to make it accessible through your own custom domain instead of the default Cloud Run URL.

🎯 Goal: Set up a custom domain mapping for your Cloud Run service to make your app accessible via www.example.com.

📋 What You'll Learn

Create a dictionary called domain_mapping with keys domain and service and values 'www.example.com' and 'my-cloud-run-service' respectively.

Create a variable called project_id and set it to 'my-gcp-project'.

Write a function called create_domain_mapping that takes domain, service, and project_id as parameters and returns a dictionary with these keys and values.

Add a final line that calls create_domain_mapping with the values from domain_mapping and project_id and assigns the result to final_mapping.

💡 Why This Matters

🌍 Real World

Custom domains make your cloud-hosted applications look professional and easier to remember for users.

💼 Career

Cloud engineers often configure custom domains to route traffic to cloud services securely and reliably.

1

Create the initial domain mapping dictionary

Create a dictionary called domain_mapping with the keys 'domain' and 'service' and the exact values 'www.example.com' and 'my-cloud-run-service' respectively.

GCP

# Your code here

Need a hint?

Use curly braces to create a dictionary with the specified keys and values.

2

Add the GCP project ID variable

Create a variable called project_id and set it to the string 'my-gcp-project'.

GCP

domain_mapping = {'domain': 'www.example.com', 'service': 'my-cloud-run-service'}
# Your code here

Need a hint?

Assign the exact string to the variable project_id.

3

Write a function to create the domain mapping dictionary

Write a function called create_domain_mapping that takes three parameters: domain, service, and project_id. The function should return a dictionary with keys 'domain', 'service', and 'project' set to the corresponding parameter values.

GCP

domain_mapping = {'domain': 'www.example.com', 'service': 'my-cloud-run-service'}
project_id = 'my-gcp-project'
# Your code here

Need a hint?

Define a function with the specified name and parameters, returning a dictionary with the keys and values from the parameters.

4

Create the final domain mapping configuration

Add a line that calls create_domain_mapping with the values from domain_mapping['domain'], domain_mapping['service'], and project_id, and assign the result to a variable called final_mapping.

GCP

domain_mapping = {'domain': 'www.example.com', 'service': 'my-cloud-run-service'}
project_id = 'my-gcp-project'
def create_domain_mapping(domain, service, project_id):
    return {'domain': domain, 'service': service, 'project': project_id}
# Your code here

Need a hint?

Call the function with the dictionary values and assign the result to final_mapping.
