 Easiest way to do it is create a pod with a single container and save its definition in a YAML file:
 
 ```bash
-kubectl run web --image=nginx --restart=Never --port=80 --dry-run=client -o yaml > pod-init.yaml
+kubectl run web --image=nginx --port=80 --dry-run=client -o yaml > pod-init.yaml
 ```
 
 Copy/paste the container related values, so your final YAML should contain the volume and the initContainer:
