As you can see you have pod called nginx, that indicates that you have had nginx server already deployed in pod on your cluster. You don't have pod called webserver that's why you're getting 

Error from server (NotFound): pods "webserver" not found  error.

Also to access nginx service try to pass curl it via ip:port:

$ curl 10.110.113.60:30985

If you point a web browser to http://IP_OF_NODE:ASSIGNED_PORT (where IP_OF_NODE is an IP address of one of your nodes and ASSIGNED_PORT is the port assigned during the create service command), you should see the NGINX Welcome page!

Take a look: nginx-app-kubernetes.

I tried the above scenario locally.

do a kubectl describe svc <svc-name> check whether it have any end-points. probably it doesn't have any endpoints
