Hi, I would like setup custom Windows cluster. For that, I have installed Rancher v2.11.3 and started setting up new Custom Cluster with RKE2 option. Rancher documentation says that I can use either Flannel or Calico for container networking for Windows cluster. But when I select Flannel, I don't see Registration command for registering Windows node. I only see Windows node registration command if I select Calico. Does Flannel not support Windows cluster OR there is bug in Rancher related to showing Windows node registration command OR I am doing something wrong. I am totally lost here... please let me know if you have any information about this.

this is a bug. appears UI was not updated when we GA’d support for flannel on windows. https://github.com/rancher/dashboard/blob/3567111c26d19a974aa69919ec321081a198e1e9/shell/models/provisioning.cattle.io.cluster.js#L853-L855

Thanks for very much for looking into this and logging the bug! Are you aware of any workaround for this bug?

not if you want to use the UI, no

I see. Can it be built from Linux node registration command?
