Is it possible to export UPD and TCP on same Loadbalancer IP?


I am on bare metal kubernetes environment using metalLB.

I want to export an own core-dns server running in kubernetes to the outside world. I would like to export port 53 via UDP and TCP on the same IP. Is there any possibility to do so?

I tried the following

  • defining udp and tcp -> multiprotocol not allowed
  • defining one udp and one tcp service for same IP -> one serivice stays pending because IP is in use.

I am using kubernetes 1.14.2.

Thanks, Andreas

Currently that is disallowed. We’ve talked about lifting that
restriction, but nobody has stepped forward to drive it.
