If you are specifying 2 ports in the yaml file the load balancer will take the whole range between the 2 ports, thus blocking and making them unable to be reused for another service, If you are already using a port ex:8086 for the forwarding rule it cannot be reused for another service. Forwarding rules define how traffic is routed from the load balancer to its backend nodes. The first node port on the service is used as health check port. Connect and share knowledge within a single location that is structured and easy to search. This is because necessary load balancer updates, such as target nodes or configuration annotations, stop being propagated to the load balancer. Disowned load balancers cannot be mutated any further, including creation, updates and deletion. In the context of a service file, this looks like: You can add firewall rules to the load balancer using the deny-rules and allow-rules annotations.
