I had setup ingress on my Kubernetes Cluster running on VMWAre virtual machines by following everything similar to the specifications here. All the ports are open and accessible.
https://github.com/nginxinc/kubernetes-ingress/tree/master/examples/complete-example
My master is x.x.x.10 and nodes are x.x.x.12 and x.x.x.13.
After the creation of ingress/controllers, I need to get the IP where the nginx-controller runs
nginx-ingress-rc-kgfmd 1/1 Running 0 21h 172.16.5.5 x.x.x.12
so, it usually runs either on x.x.x.12 or x.x.x.13, and then when I do this it hits my web service
curl --resolve master.federated.fds:80:x.x.x.12 https://master.federated.fds/coffee
where master.federated.fds is the DNS resolvable name of Master.
I need to make it work without the help of IP address and only with the DNS resolvable name or else atleast with any of the node ip's
Eg: http://node2.federated.fds/coffee, when I curl this I get Connection refused error

I see that the port 80 is listening only on the node where nginx pod runs and not on any other node. Could someone pls let me know how to access the application through all node ip's or thro a url like jciamaster.federated.fds?
Thanks,
Update:
Tried to run with nginx controller as svc as suggested by Marc

When I hit http://x.x.x.:30000/coffee it just hangs and does nothing.Anything I am doing wrong?
