# RuntimeClass First, follow the appropriate installation instructions for your version of containerd. * For 1.1 or lower, use `gvisor-containerd-shim`. * For 1.2 or higher, use `containerd-shim-runsc-v1`. # Set up the Kubernetes RuntimeClass Creating the [RuntimeClass][runtimeclass] in Kubernetes is simple once the runtime is available for containerd: ```shell cat <<EOF | kubectl apply -f - apiVersion: node.k8s.io/v1beta1 kind: RuntimeClass metadata: name: gvisor handler: runsc EOF ``` Pods can now be created using this RuntimeClass: ```shell cat <<EOF | kubectl apply -f - apiVersion: v1 kind: Pod metadata: name: nginx-gvisor spec: runtimeClassName: gvisor containers: - name: nginx image: nginx EOF ``` You can verify that the Pod is running via this RuntimeClass: ```shell kubectl get pod nginx-gvisor -o wide ``` [runtimeclass]: https://kubernetes.io/docs/concepts/containers/runtime-class/
