Loadbalancing with feign and kubernetes
Do you mean Pod by node?
To test your theory, you can continuously make a call to serviceb and bring one of the pods abruptly and see if the other pod gets the request!
k8s seems to follow random algorithm for load balancing - so there is a chance that it might send the request to the same pod which I also have seen when there is no enough request. When you can send multiple concurrent requests & continuously for certain duration, I have seen requests are distributed across all the pods.
