                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!
