Overview
kubectl auth
inspects authorization.
It can check whether an action is allowed with:
kubectl [-n <non-default-namespace>] auth can-i <verb> [<type>|<type>/<name>|<non-resource-url>
The verb is a logical Kubernetes API verb: "get", "list", "watch", "delete", etc. Type is a kubernetes resource. The name is the name of a particular resource.
It could also reconcile rules for RBAC Role, RoleBinding, ClusterRole, and ClusterRole binding objects.
The identity used to perform the call can be changed via the --as kubectl option:
kubectl -n blue --as system:serviceaccount:blue:blue-sa auth can-i get pod my-pod
