 $ kubectl create -f nginx-app.yaml
-replicationcontrollers/my-nginx
 services/my-nginx-svc
+replicationcontrollers/my-nginx

 `kubectl create` also accepts multiple `-f` arguments:
 ```bash
-$ kubectl create -f nginx-rc.yaml -f nginx-svc.yaml
+$ kubectl create -f nginx-svc.yaml -f nginx-rc.yaml
 ```
