2 weeks ago Workaround from Konstantin Rebrov :
I had similar issue with OCP 4.14. fixed it by creating manually config for CNI
cat << EOF | tee /etc/kubernetes/cni/net.d/10-containerd-net.conflist { "cniVersion": "1.0.0", "name": "containerd-net", "plugins": [ { "type": "bridge", "bridge": "cni0", "isGateway": true, "ipMasq": true, "promiscMode": true, "ipam": { "type": "host-local", "ranges": [ [{ "subnet": "10.128.0.0/14" }] ], "routes": [ { "dst": "0.0.0.0/0" }, { "dst": "::/0" } ] } }, { "type": "portmap", "capabilities": {"portMappings": true}, "externalSetMarkChain": "KUBE-MARK-MASQ" } ] } EOF
Here you need to modify your network accordingly Then restart services at the master nodes:
Describe the bug
I'm trying to install a Compact OpenShift Cluster :
Bootstrap Node 3 Master Nodes 2 Worker Nodes
Now on the Bastion Host when I'm trying to run the following command to get the ready nodes
oc get nodes
NAME STATUS ROLES AGE VERSION master01.ocp4.example.net NotReady control-plane,master 16h v1.27.6+b49f9d1 master02.ocp4.example.net Ready control-plane,master 17h v1.27.6+b49f9d1 master03.ocp4.example.net Ready control-plane,master 17h v1.27.6+b49f9d1
Trying to troubleshoot master01 node
[root@master01 ~]# journalctl -f _SYSTEMD_UNIT=kubelet.service
I get the following error

Referenced the discussion where multiple users have the same problem: https://access.redhat.com/discussions/7050416
I also have it for SCN topology, after applying the solution proposed on the comments it works
