Can I use this for private repositories?

Yes, the skill provides specific patterns for SSH agent forwarding and secret mounting to securely access private Composer, NPM, or Git registries without baking credentials into the image.

How does it handle sensitive data like API tokens?

It utilizes the --mount=type=secret syntax, which ensures that sensitive files are only available during the build process and are never stored in the final image layers.

Do I need a specific Docker version to use these features?

These features require Docker BuildKit, which is enabled by adding the # syntax=docker/dockerfile:1 header to your Dockerfile and using a modern Docker engine.

Does it support multi-platform builds?

Yes, it includes documentation and patterns for using Docker Buildx and platform-aware variables to build images for multiple architectures like amd64 and arm64.

How does this skill improve Docker build speeds?

It implements BuildKit cache mounts and parallel stage execution, allowing package manager dependencies to be reused across builds and independent stages to build simultaneously.
