Does it provide linting for Dockerfiles?

Yes, it integrates Hadolint standards to identify common mistakes, such as using the 'latest' tag or failing to clean up package manager caches.

Does it support different programming languages?

Yes, the skill includes specific optimization patterns and examples for Go, Node.js, and Python projects.

How does it handle container security?

The skill mandates the use of non-root users (UID 65532) and recommends distroless base images to minimize the attack surface of your containers.

Can it help with slow Docker builds?

Absolutely. It provides guidance on layer ordering, placing frequently changed files like source code after rarely changed files like dependency manifests to maximize cache hits.

How does this skill help reduce Docker image size?

It enforces multi-stage builds, which separate the build-time dependencies from the runtime environment, ensuring only the necessary production binaries are included in the final image.
