# Docker

Docker is a platform for developing, shipping, and running applications in containers. It enables consistent environments across development, testing, and production.

## Key Concepts

- Docker images and containers
- Dockerfile for image building
- Docker Compose for multi-container
- Volumes for persistence
- Networks for container communication

## Common Use Cases

- Application containerization
- Development environments
- CI/CD pipelines
- Microservices deployment
- Testing isolation

## Best Practices

- Use multi-stage builds
- Minimize image layers
- Don't run as root
- Use .dockerignore
- Tag images properly
