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.
Caution: This section links to third party projects that provide functionality required by Kubernetes. The Kubernetes project authors aren't responsible for these projects. This page follows CNCF website guidelines by listing projects alphabetically. To add a project to this list, read the content guide before submitting a change.

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
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.
