Hello, I have RKE2 cluster,

v1.23.7

Have following config: 1 control plane/etcd node (rhel 8) 2 Windows worker nodes. 1 is server 2022 and another is server 2019 For some reason, I see one coredns pod stays in pending state; looking at the log for that pod it does not contain any entry. So, am trying to figure out why this is?

# kubectl get pods -n kube-system | grep dns

helm-install-rke2-coredns-mn6h6 0/1 Completed 0 31d

rke2-coredns-rke2-coredns-86b4fbd678-brpcm 0/1 Pending 0 4s

rke2-coredns-rke2-coredns-86b4fbd678-csqxh 1/1 Running 0 22m

rke2-coredns-rke2-coredns-autoscaler-65c9bb465d-tcv27 1/1 Running 0 31d

Coredns can only run on Linux nodes, and both pods won't run on the same node since that doesn't give you any additional protection from a HA perspective. The pod will remain pending until you scale down the deployment, or add another Linux node for it to run on.

Many thanks for the explanation. have a great weekend
