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.
