K8s Service cluster-ip is none when map host cluster service to vCluster service

[mayooot]

What happened?

When I create a vcluster and map the host cluster's service to vcluster, use the flowing file:

$ cat values.yaml
mapServices:
  fromHost:
  - from: web-namespace/nginx-service
    to: aps/nginx-service

Everything was working fine, but I find the vcluster service cluster-ip is none, so I tried to exec a pod and use nslookup to get the actual service ip.

$ vcluster connect my-vcluster-k8s -n team-x  -- kubectl get svc -A
NAMESPACE     NAME            TYPE        CLUSTER-IP        EXTERNAL-IP   PORT(S)                  AGE
default       kubernetes      ClusterIP   192.168.194.152   <none>        443/TCP                  28h
kube-system   kube-dns        ClusterIP   192.168.194.236   <none>        53/UDP,53/TCP,9153/TCP   28h
aps           nginx-service   ClusterIP   None              <none>        80/TCP                   28h

$ vcluster connect my-vcluster-k8s -n team-x  -- kubectl exec -it curl-pod -n aps -- bash

nslookup nginx-service.aps.svc.cluster.local
Server:   192.168.194.236
Address:  192.168.194.236#53

Name: nginx-service.aps.svc.cluster.local
Address: 192.168.194.242

Obviously, 192.168.194.242 is the real k8s service cluster ip.

k get svc -A | grep nginx-service
default                    nginx-service                              ClusterIP   192.168.194.186   <none>        80/TCP                          2d5h
web-namespace              nginx-service                              ClusterIP   192.168.194.242   <none>        80/TCP                          34h

So my question is, why not show the cluster-ip in the service of vcluster? Is a bug or is it something else?

What did you expect to happen?

vcluster can show real service cluster-ip when mapping the service

How can we reproduce it (as minimally and precisely as possible)?

be like: https://www.vcluster.com/docs/v0.19/networking/internal_traffic/host_to_vcluster

Anything else we need to know?
