KEP on GitHub kep.yaml Ask about this KEP

RuntimeClass is a new cluster-scoped resource that surfaces container runtime properties to the control plane. RuntimeClasses are assigned to pods through a runtimeClass field on the PodSpec. This provides a new mechanism for supporting multiple runtimes in a cluster and/or node.
