Cloud Build Tutorial

Introduction

Google Cloud Build is a continuous integration and continuous delivery (CI/CD) platform that allows you to build, test, and deploy applications quickly on the Google Cloud Platform. This tutorial will guide you through the process of setting up and using Cloud Build, from initial configuration to deploying an application.

Prerequisites

Before you begin, ensure you have the following:

• A Google Cloud Platform account
• Google Cloud SDK installed on your local machine
• A project created in Google Cloud Platform

Step 1: Setting Up Cloud Build

First, enable the Cloud Build API in your Google Cloud project:

Next, grant the Cloud Build service account the necessary permissions:

Step 2: Creating a Cloud Build Configuration File

Cloud Build uses a YAML configuration file to define the build steps. Create a file named cloudbuild.yaml in the root directory of your project:

steps:
- name: 'gcr.io/cloud-builders/docker'
  args: ['build', '-t', 'gcr.io/YOUR_PROJECT_ID/my-app', '.']
images:
- 'gcr.io/YOUR_PROJECT_ID/my-app'
                

This configuration file tells Cloud Build to build a Docker image and push it to Google Container Registry.

Step 3: Triggering a Build

To trigger a build, run the following command:

This command submits your build configuration to Cloud Build, which then executes the steps defined in your cloudbuild.yaml file.

Step 4: Viewing Build Results

Once the build is triggered, you can view the build results in the Google Cloud Console:

This command lists all the builds in your project. You can view detailed logs of a specific build by running:

Step 5: Deploying Your Application

After building and pushing your Docker image, you can deploy it to various Google Cloud services. For example, to deploy to Google Kubernetes Engine (GKE), create a Kubernetes deployment file:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-app
spec:
  replicas: 3
  selector:
    matchLabels:
      app: my-app
  template:
    metadata:
      labels:
        app: my-app
    spec:
      containers:
      - name: my-app
        image: gcr.io/YOUR_PROJECT_ID/my-app
        ports:
        - containerPort: 8080
                

Apply the deployment file to your GKE cluster:

Conclusion

In this tutorial, you have learned how to set up and use Google Cloud Build to build, test, and deploy your applications. Cloud Build integrates seamlessly with other Google Cloud services, making it a powerful tool for managing your CI/CD pipelines.
