Other resources in this group include\n\nSubjectAccessReview : Access review for any user, not only the current one. Useful for delegating authorization decisions to the API server. For example, the kubelet and extension API servers use this to determine user access to their own APIs.\n\nLocalSubjectAccessReview : Like SubjectAccessReview but restricted to a specific namespace.\n\nSelfSubjectRulesReview : A review which returns the set of actions a user can perform within a namespace. Useful for users to quickly summarize their own access, or for UIs to hide/show actions. …\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
