Docker is an open source platform for building, deploying, and managing containerized applications. Docker is simply a popular implementation of Containers and has become a standard in the industry.
Docker uses a client-server architecture. The Docker client talks to the
Docker - Daemon, which does the heavy lifting of building, running, and distributing your Docker containers. The Docker client and daemon can run on the same system, or you can connect a Docker client to a remote Docker daemon. The Docker client and daemon communicate using a REST API, over UNIX sockets or a network interface. Another Docker client is Docker Compose, that lets you work with applications consisting of a set of containers.
