Created December 12, 2017 15:40 — forked from kevin-smets/1_kubernetes_on_macOS.md
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:

If there's output, you're good!
