GCP Cloud Functions

Build serverless applications with Cloud Functions.

Deploy Function

# Deploy HTTP function
gcloud functions deploy hello \
  --runtime=python311 \
  --trigger-http \
  --allow-unauthenticated \
  --entry-point=hello_http

# Deploy Pub/Sub triggered function
gcloud functions deploy process-message \
  --runtime=python311 \
  --trigger-topic=my-topic \
  --entry-point=process

Function Code

# main.py
def hello_http(request):
    return 'Hello, World!'

def process(event, context):
    import base64
    data = base64.b64decode(event['data']).decode('utf-8')
    print(f"Received: {data}")

Best Practices

• Use 2nd gen functions for better performance
• Implement proper error handling
• Use environment variables for configuration
• Monitor with Cloud Logging
