pod是存在的

但是kubectl exec确报这个pod不存在

sudo kubectl exec nginx-busybox -it bash

kubectl exec [POD] [COMMAND] is DEPRECATED and will be removed in a future version. Use kubectl exec [POD] -- [COMMAND] instead.

Defaulting container name to nginx.

Use 'kubectl describe pod/nginx-busybox -n default' to see all of the containers in this pod.

error: unable to upgrade connection: pod does not exist
