How do you create a temporary pod and verify a http connectivity to a service svc1 that exposed a port 80?

Run the following command:

kubectl run tmp --image=busybox --rm -i -- /bin/sh -c "wget -m 5 svc1:80"

The -m 5 parameter defines maximum time allowed for the transfer. It is used as a 5 second timeout. If the response is not transferred by that time, wget stops.
