### RuntimeClass {#runtimeclass}
{{< feature-state for_k8s_version="v1.16" state="alpha" >}}
{{< feature-state for_k8s_version="v1.20" state="stable" >}}
For [RuntimeClass](/docs/concepts/containers/runtime-class/) definitions which describe an overhead associated with running a pod,
this admission controller will set the pod.Spec.Overhead field accordingly.
If you enable the `PodOverhead` [feature gate](/docs/reference/command-line-tools-reference/feature-gates/), and define a RuntimeClass with [Pod overhead](/docs/concepts/scheduling-eviction/pod-overhead/) configured, this admission controller checks incoming
Pods. When enabled, this admission controller rejects any Pod create requests that have the overhead already set.
For Pods that have a RuntimeClass is configured and selected in their `.spec`, this admission controller sets `.spec.overhead` in the Pod based on the value defined in the corresponding RuntimeClass.
{{< note >}}
The `.spec.overhead` field for Pod and the `.overhead` field for RuntimeClass are both in beta. If you do not enable the `PodOverhead` feature gate, all Pods are treated as if `.spec.overhead` is unset.

See also [Pod Overhead](/docs/concepts/scheduling-eviction/pod-overhead/)
for more information.
