 Once the installation is over, follow these instructions to use the osmclient:
 
 ```bash
-NBI_IP=juju status --format yaml | yq r - applications.nbi-k8s.address
+NBI_IP=$(microk8s.kubectl describe -n osm ingress | grep -E "nbi.*\.io" | xargs)
 export OSM_HOSTNAME=$NBI_IP
+NBI_PASSWORD=$(juju config -m osm keystone admin-password)
+export OSM_PASSWORD=$NBI_PASSWORD
 ```
 To have the osm client always available include it in your `.bashrc`:
 
 ```bash
-NBI_IP=juju status --format yaml | yq r - applications.nbi-k8s.address
+NBI_IP=$(microk8s.kubectl describe -n osm ingress | grep -E "nbi.*\.io" | xargs)
 echo "export OSM_HOSTNAME=$NBI_IP" >> ~/.bashrc
+NBI_PASSWORD=$(juju config -m osm keystone admin-password)
+echo "export OSM_PASSWORD=$NBI_PASSWORD" >> ~/.bashrc
+```
