Ingress servers duplicated when multiple ingresses

[mikesplain]

When I test against the ingress controller in https://github.com/kubernetes/contrib/tree/master/ingress/controllers/nginx, using the ingresses in https://github.com/kubernetes/contrib/blob/master/ingress/controllers/nginx/examples/ingress.yaml, multiple of each IP are listed the server config of nginx:

    upstream default-echoheaders-x-80 {
        least_conn;
        server 10.138.27.3:8080;
        server 10.138.27.3:8080;

    }

    upstream default-echoheaders-y-80 {
        least_conn;
        server 10.138.27.3:8080;

    }

From what I can tell, this causes issues when combined with the proxy_next_upstream flag in nginx for bigger server configs like:

Is it possible to de-dup this server list or is this for some reason intentional?

is this for some reason intentional?

No, is not intentional. Different upstreams will have a different server list. In this case the services default-echoheaders-x-80 and default-echoheaders-y-80 uses the same endpoints.

Let me see if I can reproduce the duplication in the upstream of default-echoheaders-x-80

@aledbf Great thanks, let me know if you need anything from me.
