The Docker client, often simply referred to as docker, is the primary interface through which users interact with the Docker Engine. It provides a command-line interface (CLI) that allows users to manage Docker containers, images, volumes, networks, and other Docker objects.
The Docker host is the physical or virtual machine where the Docker Engine runs. It's responsible for managing and running Docker containers.
The Docker registry is a storage and distribution system for Docker images. It's where Docker users can store and share Docker images with others.
