Possible issue with partial route matches. Setting an ingress rule for /status will proxy all routes matching /status* to the associated endpoint. This may cause unexpected behavior as shown below.
$ kubectl describe svc nginx-plus-service
Name: nginx-plus-service

Labels: <none>
Selector: app=nginx-plus-ingress
Type: ClusterIP
IP: None
Port: <unnamed> 8080/TCP

Nginx ingress controller passes ingress route to the service endpoint.
$ kubectl get ing

Nginx ingress controller does not respect namespace of ingress rules.
$ kubectl get ing --namespace=test
NAME RULE BACKEND ADDRESS
nginx-ingress -
bar.baz.com
