How-to deliver a new public IP to a k8s cluster so a k8s service that requires UDP port (Bind DNS server) can use it?

I know how to expose an IP address in K8s services by defining ‘externalIPs’ attribute. It just won’t work unless the IP address is available to the cluster.

I wonder if I can attach a Floating IP to a K8s service. So far I was not able to. I need an equivalent solution, somehow.

I even tried DO’s load balancer but I could not configure it for UDP traffic.

  • I need to have 2 servers with unique IP address for use as master/slave DNS servers. And I’ve wanted to do it using Kubernetes. But I was not able to forward new instances of public IPs to it’s K8s deployment. I also fail to route UDP traffic using Digital Ocean Load Balancer.
