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
-
Adds Docker's official repository
- Downloads and installs Docker's GPG key
- Configures APT to use Docker's official package repository
-
Installs Docker components
docker-ce- Docker Community Edition enginedocker-ce-cli- Command-line interface for Dockercontainerd.io- Container runtimedocker-buildx-plugin- Extended build capabilities with BuildKitdocker-compose-plugin- Tool for defining multi-container applications
-
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
dockergroup 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
