how to check whether RBAC is enabled, using kubectl

Question

I\'m trying to install a helm package on a kubernetes cluster which allegedly has RBAC disabled. I\'m getting a permission error mentioning clusterroles.rbac.authoriza

You can check this by executing the command kubectl api-versions; if RBAC is enabled you should see the API version .rbac.authorization.k8s.io/v1.

In AKS, the best way is to check the cluster's resource details at resources.azure.com. If you can spot "enableRBAC": true, your cluster has RBAC enabled. Please note that existing non-RBAC enabled AKS clusters cannot currently be updated for RBAC use. (thanks @DennisAmeling for the clarification)
