I’m going to show how you can provision Kubernetes clusters using vRealize Automation (vRA). I’ll be using kubeadm to install the Kubernetes cluster and since kubeadm is in beta at the time of this posting and doesn’t support HA kube masters, the Kubernetes clusters will be more useful for sandbox type environments.
You’ll be able to select how many Kubernetes worker nodes you want and it will support scale out operations for the worker nodes. Scale in operations are possible, but you’d have to add additional functionality to do this. Currently I don’t have a need for this so I haven’t looked into it. As it stands, you could perform scale in operations and manually remove the longer existing Kubernetes worker nodes.
