What does the command kubectl auth can-i * * check do?

• A. It checks if the user has permissions to perform any action on any resource
• B. It lists all permissions for the current user
• C. It creates a new cluster role
• D. It validates kubectl configuration

Answer: (A)

This tests how RBAC permissions are evaluated for your current credentials. kubectl auth can-i answers whether you are allowed to perform a given action on a resource. When you use wildcards for both the verb and the resource, you’re asking: do I have any permission to do anything at all on any resource in the cluster (in the optional namespace scope you provide)? The command checks your credentials against the cluster’s Roles, ClusterRoles, and their bindings, and it returns yes if there is at least one allowed action, or no if there isn’t. It’s a quick way to verify that you have some access, not a full listing of permissions, and it doesn’t create roles or validate kubectl config.
