```

{% endtab %}

|                  |       | The read-only port for the Kubelet to serve on with no authentication/authorization (set to `0` to disable). (DEPRECATED: This parameter should be set via the config file specified by the Kubelet's `--config` flag. See <https://kubernetes.io/docs/tasks/administer-cluster/kubelet-config-file/> for more information.) |
