Easy K3s Kubernetes tools WITH K3sup and Kube-VIP

Spinning up a Kubernetes HA configuration is made easy with two open source utilities, K3sup and Kube-VIP. Using both of these utilities, we can easily stand up multiple control nodes using a virtual IP address and use the VIP to join the additional nodes to our Kubernetes cluster. For the K3s control nodes, I have spun up (3) Ubuntu Server virtual machines running in VMware vSphere.
