Multi-stage builds optimize Docker image size by copying only necessary artifacts from a build environment to a minimal final image. This Skill enforces minimal base images and caching strategies to reduce final image size and improve build performance.

Harden Docker container security by enforcing non-root users, utilizing minimal base images, and following secrets best practices. This Skill identifies security gaps and applies deployment hardening to ensure production-ready container configurations.

Orchestrate Docker Compose by applying patterns for reliable service startup, networking, and volumes. This Skill provides Compose orchestration configurations to ensure reproducible and stable multi-service deployments.

Docker deployments fail health checks when configurations lack proper endpoint definitions or resource limits. This Skill provides production deployment patterns including proper health checks and resource limits to ensure scalable and reliable configurations.

You can audit your existing Docker setup to identify containerization inefficiencies and security gaps. This Skill outputs a production-ready, optimized Dockerfile and docker-compose configuration based on reproducible guidance.
