Strange... I wonder what the difference is in my cluster.
The external IPs are fond in svc.Status.LoadBalancer.Ingress[i] if set by a cloud-provider or the metallb controller (or assign-lb-ip that I use for test).
I made a grep and found "Ingress" only in backend/iptables.
kpng > grep -r Ingress .
./backends/iptables/service.go: for _, ing := range info.loadBalancerStatus.Ingress {
./backends/iptables/service.go: //TODO : CHECK Load Balancer Ingress IPs , service.Status.LoadBalancer.Ingress
./backends/iptables/service.go: // Obtain Load Balancer Ingress IPs
./backends/iptables/service.go: // for _, ing := range service.Status.LoadBalancer.Ingress {
./backends/iptables/service.go: // info.loadBalancerStatus.Ingress = append(info.loadBalancerStatus.Ingress, v1.LoadBalancerIngress{IP: ip})

This is a bug.
Only svc.Spec.ExternalIPs are collected, but they are actually not recommended to be used and has been subject to many discussions. Basically external addresses shall not be specified by the used in the service manifest.
The external addresses are normally taken from service.Status.LoadBalancer.Ingress which is usually set by the cloud-provider or the metallb-controller, but not by the user.
For test I made a small test;
func lbIPs(svc *v1.Service) []string {
ips := []string{}
for _, i := range svc.Status.LoadBalancer.Ingress {
ips = append(ips, i.IP)
}
return ips
}
// ....
ExternalIPs: localnetv1.NewIPSet(lbIPs(svc)...),The correct way would be to concat both svc.Spec.ExternalIPs and svc.Status.LoadBalancer.Ingress into ExternalIPs.
