+# docker
+
+**Install Docker and tools**
+
+## Purpose
+
+This cube installs Docker Engine, Docker Compose, and popular Docker management tools to enable containerized application deployment and management.
+
+## What is Docker?
+
+Docker is a platform for developing, shipping, and running applications in containers. Containers package an application with all its dependencies, ensuring it runs consistently across different environments.
+
+Key benefits:
+- **Isolation**: Each container runs independently with its own filesystem, network, and processes
+- **Portability**: Containers run the same way on any system that supports Docker
+- **Efficiency**: Containers share the host OS kernel, making them lighter than virtual machines
+- **Scalability**: Easily deploy and scale containerized applications
+
+## What This Cube Does
+
+1. **Adds Docker's official repository**
+   - Downloads and installs Docker's GPG key
+   - Configures APT to use Docker's official package repository
+
+2. **Installs Docker components**
+   - `docker-ce` - Docker Community Edition engine
+   - `docker-ce-cli` - Command-line interface for Docker
+   - `containerd.io` - Container runtime
+   - `docker-buildx-plugin` - Extended build capabilities with BuildKit
+   - `docker-compose-plugin` - Tool for defining multi-container applications
+
+3. **Installs management tools**
+   - **lazydocker** - Terminal UI for Docker and Docker Compose management
+   - **docker-ctop** - Container metrics and monitoring (top-like interface for containers)
+
+## Configuration
+
+This cube currently has no configurable parameters.
+
+## Dependencies
+
+None - this cube can run standalone.
+
+## Post-Installation
+
+After deployment:
+- Add users to the `docker` group to run Docker without sudo: `sudo usermod -aG docker username`
+- Start using Docker: `docker run hello-world`
+- Use lazydocker for easy management: `lazydocker`
+- Monitor containers: `ctop`
+
+## Notes
+
+The Docker daemon starts automatically on boot. You can manage it with systemd:
+- Check status: `sudo systemctl status docker`
+- Restart: `sudo systemctl restart docker`
