NodePort mode adds port to host header rule, but shouldn't

[nhumrich]

I am using NodePort mode, so that I can point my own ALB at HAProxy. Using NodePort, I correctly get a service on node port 31485.

In my ingress, I have host based routing, for example foo.bar.com goes to my web-gateway. The rule in haproxy configuration shows up as:

acl host_acl_web-gateway.default:80-bp7jkb hdr(host) -i foo.bar.com:31485

As you can see, its adding the node port at the end. Which means that routing doesnt actually work correctly.

Is there anyway to remove the nodeport in the host routing?

This is done, since the expectation is that with NodePort mode (usually in bare metal cluster), NodePorts are used by external clients. Since you are using a manually manged ALB, this is causing problem. We are going to add the following annotation that you can apply to disable this behavior in next release (4.0.0):
ingress.appscode.com/force-service-port: true
