Kubernetes on Vagrant - Issue with requested provider

[Lachlan Gilmour]

I am following this tutorial ;
https://coreos.com/kubernetes/docs/latest/kubernetes-on-vagrant.html

Seems very simple.. I left the provide as default ( docker)
but when running vargrant up I receive the following errors:

Bringing machine 'e1' up with 'libvirt' provider...
Bringing machine 'c1' up with 'libvirt' provider...
Bringing machine 'w1' up with 'libvirt' provider...

Any errors that occurred are shown below.

An error occurred while executing the action on the 'e1'
machine. Please handle this error then try again:

The box you're attempting to add doesn't support the provider
you requested. Please find an alternate box or use an alternate
provider. Double-check your requested provider to verify you didn't
simply misspell it.

If you're adding a box from HashiCorp's Atlas, make sure the box is
released.

Looking at the .json I can see that it's requesting I use virtualbox as a provider..?

You seem to be using Vagrant with the libvirt provider. You'll need to use Virtualbox or VMware, as CoreOS does not publish vagrant images for anything other than the two mentioned.
