InsufficientPermissions

This message occurs when istioctl x precheck finds that you do not have the permissions that are necessary to install Istio.

An example

You will receive a message like this:

Error [IST0141] (Cluster) Missing required permission to create resource clusterroles (...)

How to resolve

Get the missing permissions from your cluster administrator, or install Istio with a user that has cluster administrator permissions. You can examine a permission with kubectl auth can-i:

$ kubectl auth can-i create clusterroles
