I am learning a bit about ingress. It consists of 2 parts:
I've deployed an ingress controller in namespace called ingress. I've also deployed a default backend. Now I want to deploy an application (svc, deployment of pods etc).
Do I need to deploy this application also in the namespace ingress? It seems logical to me I have to deploy a new ingress resource for every new application, but how is this working for the Ingress controller?
Do I have to create one ingress controller for every namespace or is it recommended to use on ingress controller over multiple namespaces?
The ingress resource must be in the same namespace as the backend service. This can be any namespace doesn't need to be the same as the controller
