Does it provide diagnostics for failed builds?

The skill includes automated environment detection and validation commands to diagnose build performance issues, layer caching problems, and runtime failures.

Can this skill help with container security?

Yes, it proactively implements security best practices such as non-root user execution, specific UID/GID mapping, secret management, and dropping unnecessary Linux capabilities.

How does the Docker Expert skill reduce image size?

It utilizes multi-stage build patterns and distroless image strategies to ensure only the necessary runtime dependencies are included in the final production image.

Does it support complex Docker Compose configurations?

Absolutely. It can design and troubleshoot multi-service environments featuring health checks, custom networks, volume persistence, and environment-specific overrides.

Is the Docker Expert skill useful for local development?

Yes, it provides patterns for local development workflows including volume mounting for hot-reloading, debug port exposure, and dev-container configurations.
