Is it possible to deploy an internal ingress ?

Hello everyone,

I'm new in the Kuberneted game, and i want to know if it's possible to deploy an internal ingress. I have successfully setup a Rabbitmq cluster, but i want to put it behind an Haproxy internal ingress so other services don't have to bother about cluster nodes.

I want to achieve the following architecture (note that the 2 Haproxy ingress are in fact the same).

I successfully setup Helm but i don't understand if a have to do something to make the ingress internal.

Thank you all for your help.
