Does it include security recommendations?

Yes, it enforces the use of non-root users, version pinning for base images, and includes a checklist to prevent sensitive files from being leaked via the build context.

Can it help with Docker Compose orchestration?

Absolutely. It provides standardized patterns for Compose files, including health checks, dependency management, and resource limits.

Which programming languages are supported?

While the general principles apply to all containers, the skill includes specific optimized templates for Node.js and Python applications.

How does this skill improve Docker image size?

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