Invalid port in upstream

[gianrubio]

I figure out an an issue running the master branch. The nginx-ingress mapped an invalid port "0". I have 2 ports (22/80) exposed in this pod, the port 22 was mapped incorrectly.

nginx.conf

    upstream gitlab-gitlab-80 {
        least_conn;
        server 10.1.5.21:0 max_fails=0 fail_timeout=0;
        server 10.1.5.21:80 max_fails=0 fail_timeout=0;
    }

Cmd

 ./nginx-ingress-controller --default-backend-service=kube-system/new-default-http-backend --tcp-services-configmap=kube-system/tcp-configmap --configmap=kube-system/nginx-load-balancer-conf

@aledbf I just realised the error. I don't have ingress mapping to this port 22.

$ kubectl get ingress -n gitlab gitlab -o wide
NAME      HOSTS            ADDRESS                                PORTS     AGE

I'm submiting a PR to fix this issue
