Small troubleshooting tip:
“kubeadm reset” and try to initiate the cluster again but it is failing ,due to kubelet service was not running.
Executed this command “journalctl -xeu kubelet”
Error message “Unable to update cni config: No networks found in /etc/cni/net.d”
I checked on github : https://github.com/kubernetes/kubernetes/issues/54918
Applied the workaround “chmod 777 /etc/cni/net.d” and try to start the service.
systemctl start kubelet.service
This all has been done in centos7
