Multiple upstreams by port

[sparkoo]

I have a pod with multiple containers listening on various ports and I have single service to that pod with all ports exposed. I would like to protect the service so only owner with proper authorization token can access them. As far as I understand, it would mean to deploy kube-rbac-proxy container in front of every exposed port, which is a huge cost. Is there a way how to configure single kube-rbac-proxy to do the job? Or would you recommend different solution? Would you accept the contribution to support multiple upstreams into kube-rbac-proxy?

which is a huge cost
can you elaborate on this? multiple kube-rbac-proxy instances are being used that way in quite some places.

Would you accept the contribution to support multiple upstreams into kube-rbac-proxy?
Generally, I think such an contribution would be awesome.
