Docker Architecture:
Docker uses a client-server architecture and docker client communicates with the Docker Server(Deamon) which can build docker containers. It is a Restful service where client and Server can communicate Remotely

Container lifecycle:
create -> start -> stop -> start -> restart -> pause -> unpause -> kill -> Delete

How Docker works:
Docker makes use of kernel namespaces to provide the isolated workspace called the container . When you run a container, Docker creates a set of namespaces for that container. … Each aspect of a container runs in a separate namespace and its access is limited to that namespace
