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 (virtual machines), bare metal, OpenStack clusters, and other underlying application platforms.Docker is typically used

The container is the second core concept of Docker, and the simple one is that the container is a running instance of the mirror, and the difference is that it has an extra writable file layer. If the virtual machine is simulated running a full set of operating systems (providing a running state environment and other system environments) and running on the appli
