kubectl auth can-i

Synopsis

Check whether an action is allowed.

VERB is a logical Kubernetes API verb like 'get', 'list', 'watch', 'delete', etc. TYPE is a Kubernetes resource. Shortcuts and groups will be resolved. NONRESOURCEURL is a partial URL that starts with "/". NAME is the name of a particular Kubernetes resource. This command pairs nicely with impersonation. See --as global flag.

kubectl auth can-i VERB [TYPE | TYPE/NAME | NONRESOURCEURL]
