I deployed nginx ingress by kubespray. I have 3 masters and 2 workers and 5 ingress-nginx-controller. I tried to shutdown one worker and now I see still 5 nginx ingress on all hosts.

[root@node1 ~]# kubectl get pod -n ingress-nginx -o wide

The problem is I am getting 503 error with app after one node was power off. Is some option disconnect not working ingress-nginx-controller or possibility to use round robin, please? Or could I catch non working ingress-nginx-controller and redirect traffic to correct one, please?
