07/09/2024, 2:49 PMOkay - maybe I am wrong on this ...
I think you should look at the taints (instead of labels)
Copy code
kubectl describe node <node name> Copy code
<http://node-role.kubernetes.io/etcd:NoExecute|node-role.kubernetes.io/etcd:NoExecute>
<http://node-role.kubernetes.io/control-plane:NoSchedule|node-role.kubernetes.io/control-plane:NoSchedule>hundreds-evening-84071
07/09/2024, 2:49 PMor maybe you know that already 🙂

07/09/2024, 3:07 PMif you do not want users jobs running on that node, simply add these taints:
Copy code
<http://node-role.kubernetes.io/etcd:NoExecute|node-role.kubernetes.io/etcd:NoExecute>
<http://node-role.kubernetes.io/control-plane:NoSchedule|node-role.kubernetes.io/control-plane:NoSchedule>hundreds-evening-84071
07/09/2024, 3:09 PM Copy code
kubectl taint nodes <node name> <http://node-role.kubernetes.io/controlplane=true:NoSchedule|node-role.kubernetes.io/controlplane=true:NoSchedule>
kubectl taint nodes <node name> <http://node-role.kubernetes.io/etcd=true:NoExecute|node-role.kubernetes.io/etcd=true:NoExecute>m

07/09/2024, 3:17 PMthanks! I am going to deploy a 3-node rke2 with no taints and put the Rancher server on that. I presume only one of those nodes will get the "master" label.
