Docker basic architecture

Docker uses the C/S architecture, including the client and service side. D ocker daemon accepts requests from customers as a service side and processes those requests (create, run, distribute containers). Clients and service providers can either run on a machine or communicate through the socket or RESTful API.

Docker daemon typically runs in the host host background, waiting to receive messages from the client. The Docker client provides the user with a series of executable commands that the user uses to interact with Docker daemon.
