构建生产质量级Docker镜像和容器遵循既定的最佳实践 — 针对镜像大小、安全性、缓存、配置和可靠性。遵循这些实践会产生小巧、安全、高效且易维护的镜像。
镜像大小和效率
✓ Use SMALL base images (alpine, slim, distroless) — smaller, fewer vulnerabilities
✓ MULTI-STAGE builds — exclude build tools from the final image
✓ Order Dockerfile for LAYER CACHING (dependencies before code)
✓ Use .dockerignore — exclude unneeded files (node_modules, .git, secrets) from context
✓ Combine RUN commands and clean up in the same layer (smaller layers)
