Support for static IPs - LoadBalancer i.e. MetalLB

[cervajs]

can you add example how can i specify static IPs for brokers when using LoadBalancer?

dynamic assignment is working with this config

CFK part of config

apiVersion: platform.confluent.io/v1beta1
kind: Kafka
...
  listeners:
    external:
      externalAccess:
        type: loadBalancer
        loadBalancer:
          domain: mydomain.com

metallb config

apiVersion: metallb.io/v1beta1
kind: IPAddressPool
metadata:
  namespace: metallb-system
  name: config
  labels:
    zone: east
spec:
  addresses:
  - 192.168.1.200-192.168.1.250

apiVersion: metallb.io/v1beta1
kind: L2Advertisement
metadata:
  name: first-advertisement
  namespace: metallb-system
spec:
  ipAddressPools:
  - config

[root@master01 kafka]# kubectl get svc -n confluent | grep Load
kafka-0-lb                    LoadBalancer   10.43.157.33    192.168.1.201   9092:31329/TCP                                                            3d5h
kafka-1-lb                    LoadBalancer   10.43.115.81    192.168.1.203   9092:31314/TCP                                                            8h
kafka-2-lb                    LoadBalancer   10.43.211.63    192.168.1.204   9092:30269/TCP                                                            8h
kafka-bootstrap-lb            LoadBalancer   10.43.75.152    192.168.1.202   9092:30735/TCP                                                            3d5h

but i want assigment like this
kafka-bootstrap-lb 192.168.1.210
kafka-0-lb 192.168.1.200
kafka-1-lb 192.168.1.201
kafka-2-lb 192.168.1.202

manual workaround
https://docs.redhat.com/en/documentation/openshift_container_platform/4.18/html/networking/load-balancing-with-metallb#request-specific-ip-address_configure-services-metallb

kubectl edit svc kafka-0-lb -n confluent
add "loadBalancerIP: x.x.x.x" to the spec section
i.e.

spec: 
  type: LoadBalancer
  loadBalancerIP: x.x.x.x
