In the preceding diagram, we can see how context-based (or layer 7) routing works when using an IngressController, such as Nginx. Here, we have the deployment of an application service called web. All the pods of this application service have the following label: app=web. Then, we have a Kubernetes service called web that provides a stable endpoint to those pods. The service has a (virtual) IP of 52.14.0.13 and exposes port 30044. That is, if a request comes to any node of...
