- Revised the Kubelet API Authorization with new subresources, that allow finer-grained authorization checks and access control for kubelet endpoints.
  Provided you enable the `KubeletFineGrainedAuthz` feature gate, you can access kubelet's `/healthz` endpoint by granting the caller `nodes/helathz` permission in RBAC.

  - [beta] Added ability to authenticate/authorize access to the Kubelet API ([docs](http://kubernetes.io/docs/admin/kubelet-authentication-authorization/)) ([kubernetes/features#89](https://github.com/kubernetes/enhancements/issues/89))
- **AWS**
