Kubernetes originally launched with support for Docker containers running native applications on a Linux host. Starting with [rkt](https://kubernetes.io/blog/2016/07/rktnetes-brings-rkt-container-engine-to-kubernetes/) in Kubernetes 1.3 more runtimes were coming, which lead to the development of the [Container Runtime Interface](https://kubernetes.io/blog/2016/12/container-runtime-interface-cri-in-kubernetes/) (CRI). Since then, the set of alternative runtimes has only expanded: projects like [Kata Containers](https://katacontainers.io/) and [gVisor](https://github.com/google/gvisor) were announced for stronger workload isolation, and Kubernetes' Windows support has been [steadily progressing](https://kubernetes.io/blog/2018/01/kubernetes-v19-beta-windows-support/).

The RuntimeClass resource represents a container runtime supported in a Kubernetes cluster. The cluster provisioner sets up, configures, and defines the concrete runtimes backing the RuntimeClass. In its current form, a RuntimeClassSpec holds a single field, the **RuntimeHandler**. The RuntimeHandler is interpreted by the CRI implementation running on a node, and mapped to the actual runtime configuration. Meanwhile the PodSpec has been expanded with a new field, **RuntimeClassName**, which names the RuntimeClass that should be used to run the pod.

The RuntimeClass resource is an important foundation for surfacing runtime properties to the control plane. For example, to implement scheduler support for clusters with heterogeneous nodes supporting different runtimes, we might add [NodeAffinity](/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity) terms to the RuntimeClass definition. Another area to address is managing the variable resource requirements to run pods of different runtimes. The [Pod Overhead proposal](https://docs.google.com/document/d/1EJKT4gyl58-kzt2bnwkv08MIUZ6lkDpXcxkHqCvvAp4/preview) was an early take on this that aligns nicely with the RuntimeClass design, and may be pursued further.
