The number of nodeports for the service is insufficient

[lizhipeng629]

When using a load balancer (lb) to expose services, the generated service needs to allocate a NodePort, and the default range for NodePort is 2000+. When there are too many container service ports, it can lead to a shortage of NodePort ports.

By setting the 'allocateLoadBalancerNodePorts' parameter in the service, you can control the generated service to not expose NodePort. However, this is only applicable in scenarios where LB traffic passes directly to the pod.
