Docker Installation and use

Docker is an open-source engine that makes it easy to create a lightweight, portable, self-sufficient container for any application. Developers who compile tests on notebooks can be deployed in batches in a production environment, including VMS (VMS), bare metal, OpenStack clusters, and other base application platforms. The source code of  docker is all written in go language.
