Setting Up Sander van Vugt’s CKA course With VirtualBox Notes

I want to follow Sander van Vugt’s CKA course on a home linux box using virtualbox for controller/worker nodes.

This repo seems to contain the right goodies to start with:

tl;dr – and contain the patches to get this working

What Was The Investigation?

  • cloned the upstream repos to my linux box
  • realise I don’t have virtualbox installed. Install virtualbox with dnf install virtualbox . Try to start virtualbox and receive a nice error:
; virtualbox                                                                                                                                                                                                                               
WARNING: The vboxdrv kernel module is not loaded. Either there is no module
         available for the current kernel (5.16.16-200.fc35.x86_64) or it failed to
         load. Please try load the kernel module by executing as root

           dnf install akmod-VirtualBox kernel-devel-5.16.16-200.fc35.x86_64
           akmods --kernels 5.16.16-200.fc35.x86_64 && systemctl restart vboxdrv.service

         You will not be able to start VMs until this problem is fixed.
