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

Answer 1

I wish there was a better way but what I use is:

$ kubectl cluster-info dump | grep authorization-mode

If you can execute it you should either see RBAC listed there or not, and if you don't have the permissions to do it, well, chances are that RBAC is enabled.
