Hi Team, I am trying to join the Ubuntu (18.04) machine to the STX 4.0 K8s cluster using kubeadm join, but fails because kubelet is not running properly. I installed kubeadm and kubelet node binaries of version 1.18.12. I checked the bug report and run the script (kubelet-cgroup-setup.sh) , still I get the issue. [ https://bugs.launchpad.net/starlingx/+bug/1828270] Do anybody can suggest what could be reason for it. Journalctl -f : Feb 17 15:48:33 cont0-NUC8i7HVK systemd[1]: Started Kubernetes systemd probe.
