Installing K8s on rancherOS with kubeadm?

Hi all,

We have installed Kubernetes using kubeadm on CoreOS but with the recent announcements, we want to more to rancherOS. We are however unable to find any documentation on how to install Kubernetes on rancherOS using kubeadm. We don’t want to use Rancher for this. We are trying to be as generic as possible to avoid being tied to a platform or cloud provider.

Does someone have a procedure or advice on how this can be done?

Thank you!
Edoardo
