# RuntimeClass RuntimeClass is an alpha feature for supporting multiple container runtimes within a cluster. When enabled, pods can select a RuntimeClass to run with using the `PodSpec.RuntimeClassName` field. To enable RuntimeClass, set the feature gate `RuntimeClass=true`, and ensure the CRD defined in this directory is installed.
