What are the components of Docker Architecture and explain?

This is the common Docker Interview Questions asked in an interview. The Docker works on client-server architecture. The Docker client establishes communication with the Docker Daemon. The Docker client and Daemon can run on the same system. A Docket client can also be connected to a remote Docker Daemon. The different types of Docker components in a Docker architecture are–

1. Docker Client: This performs Docker build pull and run operations to establish communication with the Docker Host. The Docker command uses Docker API to call the queries to be run.
2. Docker Host: This component contains Docker Daemon, Containers and its images. The images will be the kind of metadata for the applications which are containerized in the containers. The Docker Daemon establishes a connection with Registry.
3. Registry: This component will be storing the Docker images. The public registries are Docker Hub and Docker Cloud which can be s used by anyone.
