multi-stage-dockerfile

What problem does it solve?

This Skill helps create efficient, smaller, and more secure Docker images by leveraging multi-stage builds, reducing build times and deployment footprints.

Core Features & Use Cases

• Optimized Image Size: Reduces final image size by excluding build tools and intermediate artifacts.
• Enhanced Security: Minimizes the attack surface by including only runtime necessities.
• Reproducible Builds: Ensures consistent image creation through precise versioning and layer caching.
• Use Case: Building a Node.js application, you can use a builder stage with all npm dependencies and build tools, then copy only the compiled application code and production dependencies to a minimal runtime image.

Quick Start
