1.2.15 Ensure that the admission control plugin NodeRestriction is set

Information

Limit the Node and Pod objects that a kubelet could modify.

Rationale:

Using the NodeRestriction plug-in ensures that the kubelet is restricted to the Node and Pod objects that it could modify as defined. Such kubelets will only be allowed to modify their own Node API object, and only modify Pod API objects that are bound to their node.

Impact:

None.

Solution

None.

Default Value:

In OpenShift, the NodeRestriction admission plugin is enabled by default and cannot be disabled.
