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-serviceEverything 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: 192.168.194.242Obviously, 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 34hSo 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?
