# Cloud Build Helper

## Quick Start

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

## Instructions

### Step 1: Create cloudbuild.yaml

```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

```yaml
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

```bash
# 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:**
```yaml
steps:
  # These run in parallel
  - name: 'gcr.io/cloud-builders/npm'
    id: 'install-frontend'
    args: ['install']
    dir: 'frontend'
    waitFor: ['-']
