Layer 4 Load Balancer on vSphere

Hi everybody, I need to configure a kafka pod exposing port 9092 through a layer-4 load balancer service. As per what I have read, it seems that layer-4 load balancer are not supported outside the cloud, reason why it is recommended to use global config map and ingress option --tcp-services-configmap. I have configured the pod, as well as the config map but I am stuck on the ingress part, can somebody point me to some similar example to finalise the configuration?
Thanks a lot
