+A Terraform script to create k8s nodes. This script has modules for creating the
+nodes on a KVM/QEMU (libvirt) hypervisor or creating the nodes via AWS.

+The modules allow you create N VMs of a specific type. So you could create 1
+master node and 3 worker nodes or you could create 3 Ubuntu VMs and 5 CentOS
+VMs, or whatever fits your needs.
