What are the Docker components?

Docker consists of three components: Docker Client, Docker Host, and Docker Registry.

• Docker Client - This component executes "build" and "run" operations in order to establish communication with the Docker host.
• Docker Host - This component contains the primary Docker daemon, which connects to the Docker registry, and hosts containers and their related images.
• Docker Registry – The Docker registry, which can be private or public, is where the Docker images are stored. Docker Hub and Docker Cloud are the most well-known public registries.
