How does Docker Expert help reduce image size?

It implements multi-stage builds to separate build dependencies from runtime artifacts and utilizes minimal base images like Alpine or Distroless to ensure only necessary files are included in the final image.

Does Docker Expert support Docker Compose configurations?

Absolutely. It provides expert patterns for service orchestration, including health check strategies, network isolation, volume persistence, and resource limit definitions.

Can this skill help secure my containers for production?

Yes, it proactively implements security hardening patterns such as creating non-root users, managing secrets via BuildKit or Docker Secrets, and dropping unnecessary Linux capabilities.

When should I use this skill instead of a Kubernetes-specific one?

Use Docker Expert for image creation, local development workflows, and single-node orchestration. For managing pods, services, and ingress on a cluster, you should transition to a Kubernetes-specific agent.
