Comment 3 for bug 1832608

Hello, the bug wasn't fixed for me. The service name is still empty. I add the steps to reproduce it:

Fresh machine, Ubuntu Bionic

STEPS:
```
sudo snap install microk8s --classic
sudo snap install juju --classic --channel 2.6/edge
microk8s.status --wait-ready
microk8s.enable dashboard storage dns
sudo alias microk8s.kubectl kubectl
juju bootstrap microk8s
juju add-model osm
juju create-storage-pool operator-storage kubernetes storage-class=microk8s-hostpath
juju create-storage-pool osm-pv kubernetes storage-class=microk8s-hostpath
juju deploy cs:~charmed-osm/mongodb-k8s --channel edge -n 3

# Wait...
juju status --color
