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

1. Use caching to speed up builds
2. Implement parallel build steps
3. Use appropriate machine types
4. Store artifacts in Cloud Storage
5. Use substitution variables
6. Implement proper error handling
7. Monitor build performance
8. Use Cloud Build's built-in builders when possible
