Ingress Controllers
In order for the Ingress resource to work, the cluster must have an ingress controller running.
Unlike other types of controllers which run as part of the kube-controller-manager binary, Ingress controllers
are not started automatically with a cluster. Use this page to choose the ingress controller implementation
that best fits your cluster.
Kubernetes as a project currently supports and maintains GCE and nginx controllers.

Using multiple Ingress controllers
You may deploy any number of ingress controllers
within a cluster. When you create an ingress, you should annotate each ingress with the appropriate
ingress.class
to indicate which ingress controller should be used if more than one exists within your cluster.
If you do not define a class, your cloud provider may use a default ingress controller.
Ideally, all ingress controllers should fulfill this specification, but the various ingress controllers operate slightly differently.
Note: Make sure you review your ingress controller's documentation to understand the caveats of choosing it.
