I guess that minikube needs VirtualBox because of dockers' dependencies, but my current docker version doesn't need it.
So do I still need VirtualBox or another VM to start minikube?
this is only case on window or osx, do need virtualbox, vmware to create minikube vm using boot2docker, in Linux even Linux VM minikube can directly run kubernetes in host docker when choice --vm-driver none, which uses localkube.
