Nadav Aviv asked: Im trying to route traffic in my nginx proxy according to a received header. Follow the signs. should be forwarded to service1. With the NGINX Ingress controller you can also have multiple ingress objects for multiple environments or namespaces with the same network load balancer; with the ALB, each ingress object requires a new load balancer. In this setup, I will be using 2 MSR images which will be used in 2 deployments. Ingress supports implementations from multiple vendors such as NGNix, Kong, HAProxy, Ambassador and My infrastructure is built in a way that traffic is being sent to the proxy with a header that contains part of the address that I want to route to.

While this is powerful, if your application is living in Kubernetes and your load balancer is just routing requests to your ingress controller, you typically do not need this level of control over how you are routing requests If pathType is Exact, the controller creates a Kong route with a regular expression that matches the rule path only. This document explains how to use advanced features using annotations. All paths defined on other Ingresses for the host will be load balanced through the random selection of a backend server. Example This example demonstrates configuration of the nginx ingress controller via a ConfigMap to pass a custom list of headers to the upstream server.
