Hello,

Kubelet fails to start on worker node after installing kubeadm,kubectl & kubelet. Tried on Centos & Ubuntu and it all complains about missing /var/lib/kubelet/config.yaml file.

Finally got it working !

After installation on worker node, the kubelet service won’t start unless the node join to cluster using “kubeadm join” command which initializes the /var/lib/kubelet/config.yaml file and then starts the kubelet service.
