It is built around the Kubernetes Ingress resource, using a ConfigMap to store the NGINX configuration. Kubernetes will then wire up the loadbalancer up for you, routing it to a NodePort that is dynamically assigned. This open-source solution allows developers and system teams to manage Ingress HTTP routing, load balancing and application services. A single ingress controller can be deployed to the cluster and service requests for all namespaces in a cluster.
