I am going to stuck with run any container/POD.

Already see all answers related to the ImagePullBackOff issue here, but can not find any related solution.

Please see below output:-

shashi@master:~$ kubectl run nginx --image=nginx

kubectl run --generator=deployment/apps.v1 is DEPRECATED and will be removed in a future version. Use kubad.

deployment.apps/nginx created

shashi@master:~$ kubectl get pods --all-namespaces
