containerization
Containerization Skill
Build secure, optimized Docker containers for Node.js applications.
Core Principles
| Principle | Description |
|---|---|
| Minimal Images | Use slim base images, multi-stage builds |
| Non-root User | Never run as root in production |
| Layer Caching | Order Dockerfile for optimal caching |
| Security First | No secrets in images, scan for vulnerabilities |
| Reproducible | Pin versions, use lock files |
