How much can this skill reduce my container image size?

Reduction varies by language; typically Node.js and Python see 80-90% reduction, while compiled languages like Go and Rust can see over 99% reduction by using 'scratch' base images.

Which programming languages are supported by this skill?

The skill provides optimized multi-stage patterns for Node.js, Python, Go, Rust, and Java (OpenJDK/JRE).

What is the primary benefit of a multi-stage Docker build?

Multi-stage builds allow you to use multiple FROM statements in one Dockerfile, enabling you to build your app in a heavyweight environment and copy only the necessary artifacts into a minimal production image.

Does this skill support security-focused images like Distroless?

Yes, it includes specific patterns for Google's Distroless images, which contain only your application and its dependencies, removing shells and other tools that increase the attack surface.

Deployment & DevOps

Optimizes production Docker images using multi-stage build patterns to significantly reduce size and improve security.

This skill empowers Claude to architect high-performance Docker multi-stage builds that follow 2024-2025 industry best practices. By separating build-time dependencies from the final runtime environment, it helps developers reduce image sizes by 50-99% while minimizing the attack surface. It provides ready-to-use patterns for Node.js, Python, Go, Rust, and Java, incorporating advanced techniques like Distroless images, static linking, and non-root user configurations to ensure your containers are production-ready and cost-effective.
