ipedrazas / 1_kubernetes_on_macOS.md
Created May 11, 2019 — forked from kevin-smets/1_kubernetes_on_macOS.md
Local Kubernetes setup on macOS with minikube on VirtualBox and local Docker registry
View 1_kubernetes_on_macOS.md

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!

Prerequisites

You can’t perform that action at this time.
