All the operations mentioned here require a Red Hat account with active Red Hat Enterprise Linux and OpenShift Container Platform subscriptions. If you don't have one already, go to https://access.redhat.com and create an account.
When you deploy on VMs, make sure to plan that the zones you create on Kubernetes nodes are actually physically located on separate hypervisor nodes.
For this recipe, we need to have a minimum of six nodes with Red Hat Enterprise CoreOS installed on them. These nodes can be either bare-metal, VMs, or a mix of bare-metal and VMs.
