Answer 1

Hi@akhtar,

You may get this error if Kubectl command did not able to find your config file. So create one .kube folder and move your config file inside this folder. It will solve this error.

what is contain for Config file. where can I get it.

This config file contains the information of your Kubernetes cluster. Go to your Kubernetes master node and search .kube folder. There you can find your config file. Now You need to create .kube folder in your docker container. After that copy the config file from Master node to .kube folder in your docker container.

Answer 2

you just need to kill kubelet service and restart again. pods and container will be running as well as before reboot.

pkill kubelet

systemctl restart kubelet

good luck
