Multi-stage Dockerfiles reduce image size and improve security by separating build and runtime stages. This Skill generates optimized multi-stage Dockerfiles for Node.js, Python, Go, and Next.js applications with non-root users, minimal layers, and production-ready defaults built in.

Yes. Multi-stage builds work across Node.js, Python, Go, and Next.js by using language-specific base images in separate stages. This Skill applies the pattern to all four frameworks, reducing final image size while maintaining security standards.

Production Dockerfiles require non-root user execution, minimal attack surface, health checks, and optimized layering. This Skill generates Dockerfiles with these security-focused defaults, multi-stage layout, configurable ports, and non-root runtime setup automatically.

Multi-stage builds separate compilation, dependencies, and runtime into distinct layers, reducing artifact size and build time in CI/CD. This Skill generates optimized stage layouts for Node.js, Python, Go, and Next.js that integrate directly into pipeline workflows.

No. This Skill handles configurable port exposure automatically, generating Dockerfile EXPOSE directives based on your application type. Port configuration is set up for Node.js, Python, Go, and Next.js apps without manual editing.

This Skill supports Node.js, Python, Go, and Next.js applications. It generates language-specific base images, multi-stage layouts, and runtime configurations tailored to each framework's production requirements.
