Hi, I would like to use metallb on RKE2 provisioned cluster. I have to add this configuration to

kube-proxy

kubeproxy:
  extra_args:
  ipvs-strict-arp: 'true'
  proxy-mode: ipvs

But looks like there is no config map for kube-proxy. When I try to edit

cluster.yaml

to add custom config to kubeproxy I'm not sure where I should add this cfg. Could you help me, please? 🙂

But where? And whats the syntax for config I wrote above?

in kubelet args?

I have RKE2 cluster, GUI provisioned. There is documentation for RKE, but not for RKE2 https://www.suse.com/support/kb/doc/?id=000020035

@creamy-pencil-82913 could you help please? This is last blocker in our setup 😞

I think you put that in your systemd file for starting rke2-server or rke2-agent, though I'm not certain. Last I checked there were RKE2 docs at https://docs.rke2.io that weren't in the Rancher page (it took me several weeks to notice that link in the channel description here).

Im not sure. Every change should be in

cluster.yaml

just to be sure it will be not overwritten 🤔

No clue, but the --xxxx syntax looks more like a command line argument than yaml to me and I'm fairly sure things can be put there.

My understanding is that some options that go in the systemd file are for the static pods that get loaded for the base of the Kubernetes cluster that Rancher runs on, so for some options the config inside rancher is too late.

You are 100% right, but

--kube-proxy-arg

looks like argument you pass when you create k8s using RKE2. It's not my case. I've created cluster using GUI, then I have to change parameters in GUI (cluster.yaml). Otherwise, these changes will be overwritten

Look here - https://www.suse.com/support/kb/doc/?id=000020035 But this docs are for RKE1

I have to put similar settings in my

cluster.yaml

in GUI

documentation for RKE2 on this part is really lacking
