binding multiple host IPs to service load balancers

[jrwren]

I have k3s on a single node as my own personal little test cluster.

I want to test running 2 ingress, istio and nginxinc.

I've added an addition IP the host. Is there a way to tell ServiceLB that I now have 2 IP addresses it can use? It has already assigned one to the istio ingress (although it might be binding * instead of the specific host IP).

My guess is that I need to set the hostips somehow, somewhere, but I have not found the right docs.

If both services use the same ports, they cannot run on the same hosts. You need to use distinct ports for LoadBalancer services when using ServiceLB, if you want them to run on all nodes.
