Overview
An Ingress is a mechanism that operates at the application layer of the network stack (HTTP) and brings layer 7 features such as host and path-based routing and cookie-based session affinity to services. Ingress cooperates with services to distribute load to pods. It exposes multiple services through a single IP address, and its implementation differs fundamentally from the implementation of ClusterIP, NodePort and LoadBalancer services.
The Ingress mechanism consists of an Ingress controller and an Ingress resource.
