Analyzes and optimizes Dockerfiles to reduce image size, accelerate build times, and harden container security.
The Dockerfile Optimizer skill provides a comprehensive framework for auditing and improving container images. It guides developers through selecting minimal base images, implementing efficient multi-stage builds, and optimizing layer caching to significantly speed up CI/CD pipelines. Beyond performance, it enforces security best practices such as non-root user execution and build-dependency cleanup, making it an essential tool for DevOps engineers looking to create production-ready, lightweight, and secure container artifacts.
