Issues with Wordpress install guide

Hi,

i am having troubles with the wordpress install guide using helm at https://labs.ovh.com/kubernetes-k8s/documentation/tutorial/installing-wordpress

The install and all works well, but when i try to connect to
http://$mynodeurlfromcloudcenter:$NODE_PORT/
it seems the port is not open. I cannot connect with a browser.

If i have a look at kubectl get services, i see that the type is "LoadBalancer" for the wordpress service.
Shouldn't that be avoided by the "--set serviceType=NodePort" in the helm install command?

$ kubectl get services
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
early-rattlesnake-mariadb ClusterIP 10.3.63.40 3306/TCP 19m
early-rattlesnake-wordpress LoadBalancer 10.3.75.68 80:31528/TCP,443:30644/TCP 19m
kubernetes ClusterIP 10.3.0.1 443/TCP 57m

Regards

Marco
