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

# Install Docker Engine
curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh
