Since nginx-ingress-c ontroller:0.9.0-beta.18, annotations prefix defaults to _nginx.ingress.kubernetes.io_. Try to change your annotations to:

nginx.ingress.kubernetes.io/rewrite-target: /
nginx.ingress.kubernetes.io/ssl-redirect: "false"
nginx.ingress.kubernetes.io/force-ssl-redirect: "false"

Or specify the flag --annotations-prefix ingress.kubernetes.io when starting the controller (see Comand Line arguments)

Super helpful as the docs https://kubernetes.io/docs/concepts/services-networking/ingress/#single-service-ingress dont mention nginx.ingress.kubernetes.io vs ingress.kubernetes.io
