SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Writing Dockerfiles by hand often leads to bloated images, slow builds, and security gaps like running as root. This Skill automates Dockerfile generation with containerization best practices built in. ## Core Features & Use Cases - Auto-Detection: Identifies project type from files like pyproject.toml or Cargo.toml and selects the right template. - Multi-Stage Builds: Separates build and runtime stages to produce smaller final images for Python and Rust applications. - Security Hardening: Adds non-root users, slim base images, and .dockerignore files to reduce attack surface and build context. - Use Case: You have a new Python service and need a production Dockerfile. Invoke the skill and it generates a multi-stage Dockerfile with a non-root user, pinned base image, and a matching .dockerignore. ## Quick Start Ask Claude to generate an optimized Dockerfile for the current project using the docker skill.

Frequently Asked Questions about docker

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate a Dockerfile for a Python application?▼

Invoke the docker skill with the python argument or let it auto-detect pyproject.toml. It generates a multi-stage Dockerfile that builds a wheel in the builder stage and installs it in a slim runtime stage with a non-root user.

How do I build a small Docker image for a Rust application?▼

Use the docker skill with the rust argument to generate a multi-stage Dockerfile. It compiles the release binary in a rust:slim builder stage and copies only the binary into a debian:bookworm-slim runtime image.

What is a multi-stage Docker build and why use it?▼

A multi-stage build uses separate stages for building and running an application, copying only the compiled artifacts into the final image. This removes build tools and dependencies from the runtime image, reducing size and attack surface.

Does the generated Dockerfile run as a non-root user?▼

Yes, every generated Dockerfile creates a dedicated user with useradd and switches to it via the USER instruction before the entrypoint. This follows container security hardening best practices.

What should go in a .dockerignore file?▼

A .dockerignore should exclude .git, virtual environments, build artifacts like target/, tests, and documentation. The skill creates one automatically if missing, which speeds up builds by shrinking the build context.
