```
helm install ingress-nginx-2 ingress-nginx/ingress-nginx \
--namespace kube-system \
--set controller.electionID=nginx-two-leader \
--set controller.ingressClassResource.name=nginx-two \
--set controller.ingressClassResource.controllerValue="example.com/ingress-nginx-2" \
--set controller.ingressClassResource.enabled=true \
--set controller.ingressClassByName=true
```
