# 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
|
|
```
