8. Docker Best Practices

• 8.1 Use multi-stage builds for leaner and more secure Docker images
• 8.2. Bootstrap using ‘node’ command, avoid npm start
• 8.3. Let the Docker runtime handle replication and uptime
• 8.4. Use .dockerignore to prevent leaking secrets
• 8.5. Clean-up dependencies before production
• 8.6. Shutdown smartly and gracefully
• 8.7. Set memory limits using both Docker and v8
• 8.8. Plan for efficient caching
• 8.9. Use explicit image reference, avoid latest tag
• 8.10. Prefer smaller Docker base images
• 8.11. Clean-out build-time secrets, avoid secrets in args
• 8.12. Scan images for multi layers of vulnerabilities
• 8.13 Clean NODE_MODULE cache
• 8.14. Generic Docker practices
