Is Docker Container a Vm

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.

Does Docker create a virtual machine?

Docker isn’t a virtual machine – it is a configuration management tool. let’s not forget that Docker for Mac and Docker for Windows do use the virtualization layer.

Why Docker is faster than VM?

Since the host kernel is shared amongst Docker containers, applications only ship with what they need to run—no more, no less. This makes Docker applications easier and more lightweight to deploy and faster to start up than virtual machines.
