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 supports and maintains AWS, GCE, and nginx ingress controllers.

Using multiple Ingress controllers
You may deploy any number of ingress controllers using ingress class
within a cluster. Note the
.metadata.name of your ingress class resource. When you create an ingress you would need that name to specify the
ingressClassName field on your Ingress object (refer to IngressSpec v1 reference).
ingressClassName is a replacement of the older annotation method.
If you do not specify an IngressClass for an Ingress, and your cluster has exactly one IngressClass marked as default, then Kubernetes applies the cluster's default IngressClass to the Ingress.
You mark an IngressClass as default by setting the
ingressclass.kubernetes.io/is-default-class annotation on that IngressClass, with the string value
Ideally, all ingress controllers should fulfill this specification, but the various ingress controllers operate slightly differently.
