For my "production" homelab, I prepared 5x Bare Metal Server and installed Rancher on top of a Kubernates, also I created a new RKE2 Cluster.
Now I want add an etcd, Control Plane and two worker Nodes.
In Cluster Registry Tab is a checkbox "Show Advanced", expanded I can enter
Node Name and Public Ip is clear to me. But what is a private ip and how I can find it?
I Use Ubuntu 20 on Bare Metal.
Private IP should be in section 2: after "brd"
ip -o addr show
