Hi,

    In the openshift-ingress/router-default pod, in /var/lib/haproxy/conf/haproxy.config I see:

    I probably want "roundrobin" instead of that, though I would argue the system isn't doing what is implied by "leastconn" either. Is there a way to change that setting to what I need?

Marvin,

You can try the "haproxy.router.openshift.io/balance" annotation on your Route resource to configure the balancing strategy[1].

Hi,

    I'm using code-ready containers and I've scaled my pod to do, but when I hit it form a for loop in a shell script, I get back results indicating that its only being routed to one of the pods. Is there some setting that I need to tweak to make things load balanced even at low load?
