How does this skill improve Docker build speeds?

It implements an optimized layer caching strategy by copying dependency files and installing packages before adding source code, ensuring heavy layers aren't rebuilt on every code change.

How does it help with image size optimization?

The skill focuses on using minimal base images like Alpine Linux and provides patterns for cleaning up build-time dependencies to keep final images between 200-400MB.

What makes these Dockerfiles 'production-grade'?

They utilize multi-stage builds to separate build dependencies from the final runtime image, execute as non-root users for security, and include proper signal handling via Tini.

Does this skill support local development?

Yes, it provides detailed Docker Compose configurations that include volume bind mounts for hot-reloading and health-checked service dependencies like Redis and MongoDB.
