I've define a Ingress rule on path /grafana I understand that I need also to configure root_url I'm looking for the correct way to pass the root_url = %(protocol)s://%(domain)s:%(http_port)s/grafana/ with a command line like :

helm install --namespace grafana -n grafana stable/grafana --set rbac.pspEnabled=false  --set grafana.ini="{root_path = https://ingress-ops.nd-int-ops-paas.itn/grafana/ }"

I don't know what's wrong
