[Starlingx-discuss] failed to run Kubelet: invalid configuration: cgroup-root ["k8s-infra"] doesn't exist

[Shashi, Yatindra]

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.
