I would be really interested in exploring multi-master k8s cluster but it is not in proposal at the moment. We can surely look into this. FS mentions, for deployment, plugin will use kubeadm and kubectl tools.

How would the k8s cluster would be created, using Rancher tools, kubectl or other? so far, the small part I understand from MaaS, it could be very interesting to integrate it to cloudstack in a way where it could be use to scale Hypervisor host, specially KVM nodes.
