yes，maybe can support more ways，for example
1. dns
2. Kubernetes service
Maybe kubernetes service load balancer mode is a better way,but the way depends on cloud (aws,Ali),it would be not work in a privite kubernetes cluster
So.i want to add the feature, like kubernetes dubbo
1.Use kubernetes service self support
1.if have time,also supports dns nslookup

If you want to add new dependency on the agent core, that wouldn't be recommended, especially for this case. The way would be adding a plugin for feature extension. If there is no extension point currently, we could create one.
Anymore, I need more details about what you are trying to do. Because I don't know what dubbo-k8s did, actually, that is not have to be our reference. Agent is very different from a dev framework.

OK, that will not be an easy job. NOTICE, receiver role OAP role is never registered through the coordinator, but your service discovery is for looking up receiver role nodes.

Do you have more material about DNS level load balancer can't work automatically? From your asking, it seems, we need codes to do a DNS lookup to get the candidate list. Am I right?

i found the purpose of boot service int erface for single purpose.
if we want to support the polymorphism in service discovery.
2 ways:
1. modify the boot service to support polymorphism
2. add a new interface.
Do you have any Suggestions

Just confirm, you want to do `DNS lookup` manually by codes, then select the backend from candidates?

And service discovery of OAP node is not recommended in many companies, because the OAP nodes are deployed in the system/operation platform zone, rather than the business zone. Service discovery wouldn't work in this case.

yes，i should change a new title
build the connection between agent client and oap server with service discover
for example :
Kubernetes
dns
etcd
zk
.....
create a new extension point like oap
