Docker architecture
Docker uses the client-server (C/S) schema pattern and a remote API to manage and create Docker containers.
Docker containers are created by Docker images.
Containers have a similar relationship to mirrors to objects and classes in object-oriented programming.

Docker Mirror (Images) |
Docker mirroring is a template for creating Docker containers, such as Ubuntu systems. |
|
Docker Container |
A container is one or a group of apps that runs independently and is an entity that mirrors the runtime. |
|
Docker Client |
Docker clients communicate with Docker's daemons using the Docker API (https://docs.docker.com/reference/api/docker_remote_api) on the command line or other tools. |
|
Docker Host |
A physical or virtual machine is used to perform Docker daemons and containers. |
|
Docker Warehouse (Registry) |
Docker repositories are used to hold images and can be understood as code repositories in code control. Docker Hub (https://hub.docker.com) provides a large collection of mirrors for use. |
|
Docker Machine |
Docker Machine is a command-line tool that simplifies Docker installation, allowing you to install Docker on platforms such as VirtualBox, Digital Ocean, and Microsoft Azure with a simple command line. |
