I accidentally deployed a control plane node as “All”. I am trying to remove the “worker” role off that server. I have tried going into cluster >nodes>edit config of the node, removed the “node-role.kubernetes.io/worker=true” saved, and it’s still showing “Roles” All everywhere in the UI. I have also tried doing it via kubectl “kubectl label node nodename node-role.kubernetes.io/worker-“ And it still shows up with “control-plane,etch,master,worker” This can’t be normal.

Management of cluster lifecycle and nodes is done through the Cluster Management area of the UI

So I am getting rancher to do the deployment. I must be missing something because I see no way of modifying it. I tried these instructions https://www.suse.com/support/kb/doc/?id=000021557 and they don’t seem to work.

What type of cluster is it? Depending on type, it should be visible in if you go to

Cluster Management

-->

Clusters

list --> find your cluster and click on the three dot button on the right -->

Edit Config

--> node/machine config should be near the top of that page

When i click on the cluster “Edit Config” i see no “node/machine” config

is your cluster rke1, rke2, eks, aks, harvester, imported??

there should be a section above that titled

Machine Pools

which contains configuration for machines and their roles

no errors i can see

It looks like a custom cluster, rather than one provisioned by rancher (where rancher will create the resources required to run kube in). to confirm you provisioned the nodes yourself and then ran rancher registration commands in them?

Yes, I did “Use Existing nodes and create a cluster using RKE2/K3s”

@creamy-pencil-82913 might be able to help advise if nodes in an rke2 cluster setup via a

custom

ui cluster registration command can have their roles changes

idk, this is something on the rancher side, not rke2… I suspect that the roles are being enforced by rancher-system-agent. When you register a custom node the roles are just appended to the generated registration command, note the flags at the end:

curl -fL <https://rancher-X/system-agent-install.sh> | sudo sh -s - --server <https://rancher-X> --label '<http://cattle.io/os=linux|cattle.io/os=linux>' --token 123 --etcd --controlplane --worker

yeah, i tried the instructions with just changing to label and the taints but something is automatically adding the node labels back. Only way I was able to get it working was the remove the node and add it back like you mentioned.
