I want a command to check if ping utility is present in a pod i tried this

```
kubectl exec -it auxiliary-etcd-ubuntu -n kube-system -c etcd-auxiliary-0 ping -c 1 127.0.0.1 ; echo $?

```

Response is.

```
Error from server (BadRequest): container 1 is not valid for pod auxiliary-etcd-ubuntu
1

```

Is there any other better to just check if ping utility is already present or installed in a kubernetes pod.

Thanks in advance.
