Does it support Docker Compose?

Absolutely. It specializes in orchestrating multi-service environments with sophisticated health checks, custom networks, and specific resource constraints.

When should I use this skill instead of a general DevOps expert?

Use this skill specifically when focusing on the inner workings of Dockerfiles, image size optimization, and local container orchestration rather than broad cloud provider infrastructure or Kubernetes.

How does the Docker Expert skill reduce image sizes?

It utilizes multi-stage builds, selects minimal base images like Alpine or Distroless, and optimizes layer caching to exclude build-time dependencies from the final runtime image.

Can this skill help with container security?

Yes, it implements non-root user configurations, secret management best practices, and minimal attack surface strategies to harden your containerized applications.
