Build triggers configuration in GCP - Mini Project: Build & Apply

Build triggers configuration

📖 Scenario: You are setting up an automated build process in Google Cloud Platform (GCP). This process will start a build whenever code is pushed to a specific branch in your repository.

🎯 Goal: Create a build trigger configuration that listens to pushes on the main branch of a GitHub repository and starts a build using a specified build configuration file.

📋 What You'll Learn

Create a dictionary named trigger_config with the exact keys and values for the build trigger.

Add a branch_name variable set to main to specify which branch triggers the build.

Use the trigger_config dictionary to set the trigger's branch filter using the branch_name variable.

Complete the build trigger configuration with the required fields for GitHub repository and build configuration file.

💡 Why This Matters

🌍 Real World

Automating builds on code changes helps teams deliver software faster and with fewer errors.

💼 Career

Understanding build triggers is essential for roles in DevOps, cloud engineering, and software development automation.

1

Create initial build trigger dictionary

Create a dictionary called trigger_config with these exact keys and values: 'name' set to 'my-build-trigger', 'description' set to 'Trigger for main branch builds', and 'github' set to an empty dictionary {}.

GCP

# Create the initial build trigger dictionary
# Your code here

Need a hint?

Use a dictionary with keys 'name', 'description', and 'github'. Set 'github' to an empty dictionary.

2

Add branch name variable

Create a variable called branch_name and set it to the string 'main'.

GCP

trigger_config = {
    'name': 'my-build-trigger',
    'description': 'Trigger for main branch builds',
    'github': {}
}
# Create a variable called branch_name and set it to 'main'
# Your code here

Need a hint?

Assign the string 'main' to the variable named branch_name.

3

Set branch filter in trigger configuration

Inside the trigger_config dictionary, set the github key to a dictionary with a key 'push' that contains another dictionary with the key 'branch' set to the variable branch_name.

GCP

trigger_config = {
    'name': 'my-build-trigger',
    'description': 'Trigger for main branch builds',
    'github': {}
}
branch_name = 'main'
# Set the branch filter inside trigger_config['github'] using branch_name
# Your code here

Need a hint?

Update the 'github' key to include a nested dictionary for 'push' with 'branch' set to branch_name.

4

Complete build trigger with repo and build config

Add to trigger_config['github'] the keys 'owner' set to 'example-owner', 'name' set to 'example-repo', and add a key 'build' with a dictionary containing 'build_config' set to 'cloudbuild.yaml'.

GCP

branch_name = 'main'
trigger_config = {
    'name': 'my-build-trigger',
    'description': 'Trigger for main branch builds',
    'github': {
        'push': {
            'branch': branch_name
        }
    }
}
# Add 'owner', 'name', and 'build' keys to trigger_config['github']
# Your code here

Need a hint?

Add the repository owner and name, and specify the build configuration file inside the 'github' dictionary.
