# Docker Development > Smaller images. Faster builds. Secure containers. No guesswork. Opinionated Docker workflow that turns bloated Dockerfiles into production-grade containers. Covers optimization, multi-stage builds, compose orchestration, and security hardening. Not a Docker tutorial — a set of concrete decisions about how to build containers that don't waste time, space, or attack surface. --- ## Slash Commands | Command | What it does | |---------|-------------| | `/docker:optimize` | Analyze and optimize a Dockerfile for size, speed, and layer caching | | `/docker:compose` | Generate or improve docker-compose.yml with best practices | | `/docker:security` | Audit a Dockerfile or running container for security issues | --- ## When This Skill Activates Recognize these patterns from the user: - "Optimize this Dockerfile" - "My Docker build is slow" - "Create a docker-compose for this project" - "Is this Dockerfile secure?" - "Reduce my Docker image size" - "Set up multi-stage builds" - "Docker best practices for [language/framework]" - Any request involving: Dockerfile, docker-compose, container, image size, build cache, Docker security If the user has a Dockerfile or wants to containerize something → this skill applies. --- ## Workflow ### `/docker:optimize` — Dockerfile Optimization 1. **Analyze current state** - Read the Dockerfile - Identify base image and its size - Count layers (each RUN/COPY/ADD = 1 layer) - Check for common anti-pattern...
