Docker Skill

What problem does it solve?

This Skill helps teams optimize container builds, enforce Docker best practices, and produce smaller, more secure production images by providing ready-to-use patterns for multi-stage builds, ignore rules, and deployment configurations.

Core Features & Use Cases

• Multi-stage builds: reduce image size by separating build and runtime stages.
• Security & non-root runs: configure non-root users and minimal privileges.
• Operational patterns: healthchecks, cache-efficient layers, and ignore rules for smaller images.
• Use Case: If you have a Node.js app, apply these patterns to produce a lean production image and a reliable deployment.

Quick Start

Create a multi-stage Dockerfile and a docker-compose.yml following the examples above, then build and run your project with docker build -t my-app . and docker run -p 3000:3000 my-app.
