OpenShift + Istio : cluster-admin role mandatory for mesh management?

Hello guys,

Maybe it’s not the place to put this question, but i need your opinions.

Situation:
With istio 1.2.2 running on OpenShift Enterprise 3.11, is it mandatory to have cluster-admin role for a given user in order to manage Istio ? I mean, creating, Gateways, DestinationRules, ServiceEntries,…and all istio related components ?

is there any roles combination that is not Cluster-Admin level and permit to manage istio on OpenShift ?

Thank you in advance.
Cheers.
