Load balance pods with Nginx ingress

Question

How to balance requests between each pod using proxy-next-upstream setting on Nginx ingress. Nginx ingress should try all pods available before returning an error to client.

If I understand correctly ingress is going to load balance between services not pods. So if there is one service proxy-next-upstream is useless? Should I create separate service for each pod or there are better solutions?

Answer 1

The ingress in your case will have a service type object as backend. The service itself then has multiple pods as backends to it. This way in a micro service architecture one ingress can have multiple services as backends for example for multiple different URL contexts that are served by different applications.
