Cloud Build Helper

Quick Start

Configure Cloud Build pipelines with proper caching and optimization for fast, efficient builds.

Instructions

Step 1: Create cloudbuild.yaml

steps:

Build step

• name: 'gcr.io/cloud-builders/docker' args: ['build', '-t', 'gcr.io/$PROJECT_ID/myapp:$COMMIT_SHA', '.']

Push to registry

• name: 'gcr.io/cloud-builders/docker' args: ['push', 'gcr.io/$PROJECT_ID/myapp:$COMMIT_SHA']

Deploy

• name: 'gcr.io/cloud-builders/gcloud' args:
  • 'run'
  • 'deploy'
  • 'myapp'
  • '--image=gcr.io/$PROJECT_ID/myapp:$COMMIT_SHA'
  • '--region=us-central1'

images:

• 'gcr.io/$PROJECT_ID/myapp:$COMMIT_SHA'

options: machineType: 'N1_HIGHCPU_8' logging: CLOUD_LOGGING_ONLY

Step 2: Configure caching

steps:

• name: 'gcr.io/cloud-builders/docker' entrypoint: 'bash' args:
  • '-c'
  • | docker pull gcr.io/$PROJECT_ID/myapp:latest || exit 0 docker build
    --cache-from gcr.io/$PROJECT_ID/myapp:latest
    -t gcr.io/$PROJECT_ID/myapp:$COMMIT_SHA
    -t gcr.io/$PROJECT_ID/myapp:latest
    . docker push gcr.io/$PROJECT_ID/myapp:$COMMIT_SHA docker push gcr.io/$PROJECT_ID/myapp:latest

Step 3: Set up build triggers

Create trigger from GitHub

gcloud builds triggers create github
--repo-name=my-repo
--repo-owner=my-org
--branch-pattern="^main$"
--build-config=cloudbuild.yaml

Create trigger with substitutions

gcloud builds triggers create github
--repo-name=my-repo
--repo-owner=my-org
--branch-pattern="^main$"
--build-config=cloudbuild.yaml
--substitutions=_ENV=production,_REGION=us-central1

Step 4: Optimize build performance

Use parallel steps:

steps:

These run in parallel

• name: 'gcr.io/cloud-builders/npm' id: 'install-frontend' args: ['install'] dir: 'frontend' waitFor: ['-']

• name: 'gcr.io/cloud-builders/npm' id: 'install-backend' args: ['install'] dir: 'backend' waitFor: ['-']

This waits for both

• name: 'gcr.io/cloud-builders/npm' args: ['run', 'build'] waitFor: ['install-frontend', 'install-backend']

Best Practices

• Use caching to speed up builds

• Implement parallel build steps

• Use appropriate machine types

• Store artifacts in Cloud Storage

• Use substitution variables

• Implement proper error handling

• Monitor build performance

• Use Cloud Build's built-in builders when possible
