Docker and containerization toolkit — Dockerfile best practices (multi-stage builds, layer caching, distroless/scratch, Node.js/Python/Go patterns), Docker Compose (services, networks, health checks, profiles, dev/prod overrides), container debugging (6-step framework, exit codes, logs, exec, networking, resources), image optimization (dive analysis, size reduction, BuildKit cache mounts, buildx multi-arch), Docker networking (bridge, overlay, DNS, service discovery, port mapping), and container security (rootless, image scanning, secrets, capabilities, hardening checklists). 6 skills, 3 commands, 1 agent. No dependencies.
