明白，其实老项目简单挂一个sidecar也可以快速实现，主程序不用改代码。我们这边是这么玩的哈..

1、My kubernetes network plugin is not stable, So i have to use host network of pods. There are many service names , they provide same application with different ports.
2、To avoid http status like 504,502 ..., I can add/delete svc on apisix when pods are rolling update.

你这个场景，还不如应用将主机IP和端口注册到eureka这种注册中心，然后对接APISIX即可，和微服务服务发现差不多的套路。

I don't think this is a "multi service name" problem, but a "multi upstream" problem.

If I understand correctly, you deploy many of the same services to deal with network instability (bless at least one of them is a stable service).
IMO, Then this is equivalent to ensuring high availability of the service at the design level instead of relying on k8s, which is not good design and seems redundant.
It may be possible to support multiple service_names, but it's a bit awkward in this scenario.

自己写的哈，基于Python或者Golang都可以，功能就是将应用的端口等信息注册到注册中心

The use case is not so general IMHO. It's just like a hack way to support multiple service names.

I think this problem should be solved by routing forwarding instead of "support multiple service_names"
