Ingress Controller​

An Ingress Controller is a daemon running in a Pod which watches the /ingresses endpoint on the API server, which is found under the networking.k8s.io/v1beta1 API group.

Multiple Ingress Controllers can be deployed. Traffic should use annotations to select the proper controller. The lack of a matching annotation will cause every controller to attempt to satisfy the ingress traffic.

The most popular Ingress Controller is nginx.

As with any Ingress Controller, there are some configuration requirements for proper deployment. Customization can be done via a ConfigMap, Annotations.
