Is Docker a virtual machine?

Docker is container based technology and containers are just user space of the operating system. … In Docker, the containers running share the host OS kernel. A Virtual Machine, on the other hand, is not based on container technology. They are made up of user space plus kernel space of an operating system.

In conclusion, Docker is popular because it has revolutionized development. Docker, and the containers it makes possible, has revolutionized the software industry and in five short years their popularity as a tool and platform has skyrocketed. The main reason is that containers create vast economies of scale.
