First, kubernetes discovery provides pod's ip:port , not service's
And how to access pod's ip:port is actually not the responsibility of discovery
Normally, programs running on kubernetes nodes can directly access the pod ip,
You can deploy apisix on a node of your cluster
As for the "NodePort" you mentioned, it has nothing to do with your goal

Discovery will read config.service.host and config.service.port values at startup, and then use host:port to communicate with apiserver.
> 那服务发现怎么知道apisix是部署在集群内部还是外部
apisix discovery does not know whether it is running inside or outside the pod.
It is only when the user does not configure config.server.host, config.server.port values,
read the environment variables
$KUBERNETES_SERVICE_HOST
$KUBERNETES_SERVICE_PORT
instead.
In Pod, these two environment variables have value
And if you need to deploy apisix outside the cluster, you can also set these two environment variables pointing to apiserver
