Components of Docker

A. Docker Daemon:

Ø Docker runs on host O.S

Ø It is responsible for the running container to manage docker services.

Ø Docker daemons can communicate with other daemons.

B. Docker Client

Ø Docker users can interact with docker through a client.

Ø Docker Client uses commands and REST APIS to communicate with the docker daemon.

Ø When a Client runs any server command on the docker client terminal, the client terminals send these docker commands to the docker daemon.

Ø It is possible for Docker client to communicate with more than one daemon.

C. Docker Host

o Public Registry

o Private Registry

E. Docker Images
