Overview

Package runtimeclass contains an admission controller for modifying and validating new Pods to take RuntimeClass into account. For RuntimeClass definitions which describe an overhead associated with running a pod, this admission controller will set the pod.Spec.Overhead field accordingly. This field should only be set through this controller, so vaidation will be carried out to ensure the pod's value matches what is defined in the coresponding RuntimeClass.
