What problem does it solve? Container builds that are slow, images that are bloated, security scans that fail, and Compose services that won't communicate are common Docker pain points. This Skill analyzes your container setup and applies proven optimization, hardening, and orchestration patterns to fix them. ## Core Features & Use Cases - Dockerfile Optimization: Applies multi-stage builds, layer caching strategies, and base image selection (Alpine, distroless, scratch) to reduce image size and build time. - Security Hardening: Configures non-root users, secrets management via BuildKit mounts, and minimal attack surfaces to pass security scans. - Compose Orchestration: Designs production-grade docker-compose setups with health checks, service dependencies, custom networks, and resource limits. - Use Case: Your Node.js image is 1.2GB and builds take 10 minutes. The Skill restructures it into a multi-stage build with dependency caching and a distroless runtime, cutting size and build time dramatically. ## Quick Start Ask the AI to review my Dockerfile and docker-compose.yml for size optimization, security issues, and production readiness.
