Statefulset dns issue

Rancher 2.x
1

Hi,
I’v noticed that deploying a Statefulset through rancher resolves in spec.serviceName=""
This results in pods not being able to resolve each others.
with servicename:
hostname -f => ppp-0.ppp.default.svc.cluster.local
without:
hostname -f => ppp-0

This feels like an important issue.

For the record:
It’s apparently been fixed in 2.1
