Installing minikube using xhyve driver

###Install docker-machine-driver-xhyve docker-machine-driver-xhyve is a docker machine driver plugin for xhyve native OS X Hypervisor. xhyve is a lightweight OS X virtualization solution. In my opinion, it's a far better option than virtualbox for running minikube. ####Brew On MacOS sierra, download latest using

brew install docker-machine-driver-xhyve --HEAD
sudo chown root:wheel $(brew --prefix)/opt/docker-machine-driver-xhyve/bin/docker-machine-driver-xhyve
sudo chmod u+s $(brew --prefix)/opt/docker-machine-driver-xhyve/bin/docker-machine-driver-xhyve

Local Kubernetes setup on macOS with minikube on VirtualBox and local Docker registry

Requirements

Minikube requires that VT-x/AMD-v virtualization is enabled in BIOS. To check that this is enabled on OSX / macOS run:

sysctl -a | grep machdep.cpu.features | grep VMX

If there's output, you're good!
