I do have an Ubuntu VM in VirtualBox on Windows 10. If i follow the instructions to install Minikube I get a start error:

> minikube start &
[1] 4297
vagrant@ubuntu-xenial:~$ o   minikube v0.35.0 on linux (amd64)
>   Creating virtualbox VM (CPUs=2, Memory=2048MB, Disk=20000MB) ...
@   Downloading Minikube ISO ...
184.42 MB / 184.42 MB [============================================] 100.00% 
0s
!   Unable to start VM: create: precreate: VBoxManage not found. Make sure 
VirtualBox is installed and VBoxManage is in the path

Does it mean i need to install VirtualBox in the Ubuntu VM too? Kind of VB inside VB..

thanks

I'd recommend to install Minikube on your host OS (Windows) and use the already installed Virtual box as a hypervisor provider.

If for any reason you want to launch it on Ubuntu VM, there are two options:

I. Minikube supports a --vm-driver=none option that runs the Kubernetes components on the host and not in a VM. Using this driver requires Docker and a Linux environment, but not a hypervisor. In this case you have to provide an address to you local API server 

 `minikube start --vm-driver=none --apiserver-ips 127.0.0.1 --apiserver-name localhost`

And then go and edit ~/.kube/config, replacing the server IP that was detected from the main network interface with "localhost". For example:

apiVersion: v1
   clusters:
     - cluster:
       certificate-authority-data:/home/asuh/.minikube/ca.crt
       server: https://localhost:8443
     name: minikube

II. Install VM Ware on Windows and run Ubuntu within installed Virtualbox and and enabled VT-X/AMD-v in outer VM.

Regarding the error you have at the moment:

However now i get another error like: /usr/local/bin/minikube: cannot execute binary file

Make sure you have installed a proper version of Minikube. For your Ubuntu VM it should be

curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 \
  && chmod +x minikube

  • many thanks. Can you please elaborate more on the configuration of the solution II ? What would be the difference to have VMWare? – toto' Mar 26 '19 at 13:13

    @toto' Virtual Box does not support VT-X/AMD-v in nested virtualization while VMWare does – A_Suh Mar 26 '19 at 14:09

It is not recommended to use VM inside VM to run minikube. Check this answer. Try to run minikube with no vm drivers.

minikube start --vm-driver=none

I have read on minikube issues, but can not find it right now.

  • What is the reason behind installing minikube on VM? Why can't you just install Minikube on your host OS (Windows) and use already installed VirtualBox as a hypervisor provider? – A_Suh Mar 25 '19 at 11:43
