• Take me to the Video Tutorial

In this section, we will take a look at Using Runtimes in Kubernetes.

How to instruct the pods to specifically make use of the gvisor runtime?

gvisor.yaml

apiVersion: node.k8s.io/v1  
kind: RuntimeClass
metadata:
  name: gvisor  
handler: runsc

kubectl create -f gvisor.yml

Specify a runtimeClassName in the Pod spec:

gvisor-nginx.yaml

apiVersion: v1
kind: Pod
metadata:
  name: nginx
spec:
  runtimeClassName: gvisor
  containers:
  - image: nginx
    name: nginx

kubectl create -f gvisor-nginx.yaml
