Docker

This skill gives Claude the knowledge to containerize your application with Docker, from writing optimized Dockerfiles to orchestrating multi-container setups with Docker Compose. It covers the practical stuff: multi-stage builds to keep images small, layer caching strategies so rebuilds don't take forever, and real examples across Node, Python, and Go. The progressive disclosure is well structured, starting with a quick three-step setup and expanding into production patterns and debugging. Honestly, the framework examples section could be deeper, but the core concepts and compose configurations are solid enough to get a full stack app running locally or help you troubleshoot why your build is slow.

Docker Containerization Skill

Summary

Docker provides containerization for packaging applications with their dependencies into isolated, portable units. Containers ensure consistency across development, testing, and production environments, eliminating "works on my machine" problems.

When to Use

Local Development: Consistent dev environments across team members
CI/CD Pipelines: Reproducible build and test environments
Microservices: Isolated services with independent scaling
Production Deployment: Portable applications across cloud providers
Database/Service Testing: Ephemeral databases for integration tests
Legacy Application Isolation: Run incompatible dependencies side-by-side

Quick Start

1. Create Dockerfile

FROM node:18-alpine
WORKDIR /app
COPY package*.json ./
RUN npm ci --only=production
COPY . .
EXPOSE 3000
CMD ["node", "server.js"]

2. Build Image

docker build -t myapp:1.0 .

3. Run Container

docker run -p 3000:3000 myapp:1.0
