Before you start using the Ingress resource, there are a few things you should understand. The Ingress is a beta resource, not available in any Kubernetes release prior to 1.1. You need an Ingress controller to satisfy an Ingress, simply creating the resource will have no effect. Before you start using the Ingress resource, there are a few things you should understand.

On GCE/GKE there should be a [L7 cluster addon](https://github.com/kubernetes/contrib/blob/master/ingress/controllers/gce/README.md), deployed into the `kube-system` namespace: GCE/GKE deploys an ingress controller on the master. You can deploy any number of custom ingress controllers in a pod. You must annotate each ingress with the appropriate class, as indicated [here](https://github.com/kubernetes/contrib/tree/master/ingress/controllers/nginx#running-multiple-ingress-controllers) and [here](https://github.com/kubernetes/contrib/blob/master/ingress/controllers/gce/BETA_LIMITATIONS.md#disabling-glbc).
```shell
$ kubectl get pods --namespace=kube-system -l k8s-app=glbc
NAME READY STATUS RESTARTS AGE
l7-lb-controller-v0.6.0-chnan 2/2 Running 0 1d
```
Make sure you review the [beta limitations](https://github.com/kubernetes/contrib/tree/master/ingress/controllers/gce/BETA_LIMITATIONS.md) of this controller. In environments other than GCE/GKE, you need to [deploy a controller](https://github.com/kubernetes/contrib/tree/master/ingress/controllers) as a pod.
