# Docker

## When to Use This Skill

### USE when:

- Building reproducible development environments
- Creating consistent CI/CD pipelines
- Deploying microservices architectures
- Isolating application dependencies
- Packaging applications for distribution
- Setting up local development with multiple services
- Need portable environments across teams
### DON'T USE when:

- Simple scripts that don't need isolation
- Applications that require direct hardware access
- Environments where containers aren't permitted
- Tasks better suited for virtual machines (full OS isolation)
- When simpler alternatives like venv suffice

## Prerequisites

### Installation

**Linux (Ubuntu/Debian):**
```bash
# Install Docker Engine
curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh

# Add user to docker group
sudo usermod -aG docker $USER
newgrp docker
