docker-optimization

What problem does it solve?

This Skill reduces the overhead of Docker image maintenance by teaching you how to shrink images, speed up builds, and harden security.

Core Features & Use Cases

• Multi-stage builds: dramatically reduce final image size by separating build-time tools from runtime.
• Layer caching strategies: optimize Dockerfile instructions to maximize cache hits during rebuilds.
• Security hardening: implement non-root execution, minimal base images, and integrated vulnerability scanning in CI.
• Use Case: In a microservices repository, apply the patterns to multiple services to achieve consistent, smaller, faster deployments.

Quick Start

Apply the docker-optimization patterns to your Dockerfile. Start with converting to a multi-stage build, reorder COPY instructions to improve caching, and enable non-root execution. Then run a local build to compare image size and build time.
