+As nginx ingress is hungry for memory, let´s reduce the number of workers to 1:
+```
+kubectl -n ingress-nginx edit configmap my-release-ingress-nginx-controller
+
+apiVersion: v1
+<<<ADD BEGINN>>>
+data:
+  worker-processes: "1"
+<<<ADD END>>>
+kind: ConfigMap
+[...]
+```
+Finally the deployment needs to be restarted:
+
+`kubectl -n ingress-nginx rollout restart deployment my-release-ingress-nginx-controller`
