hi, how do I update service “kube-dns” in namespace kube-system to IPv6 from IPv4 ? Now ClusterIP of service “kube-dns” is IPv4, following as :

[root@test ~]# kubectl get svc kube-dns -n kube-system
NAME       TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)                  AGE
kube-dns   ClusterIP   10.96.0.10   <none>        53/UDP,53/TCP,9153/TCP   24h
[root@test ~]#

You can’t change to IP family wholesale, but you can add IPv6 to it, or you can just delete it and recreate it with v6
