Question

If you scale up a Pod in Openshift3, all requests coming from the same client IP address are sent to container which has the session associated.

Is there any config

Answer 1

oc set env dc/router ROUTER_TCP_BALANCE_SCHEME=roundrobin will change the load balancing algorithm haproxy uses for routes it just passes through (default is source). ROUTER_LOAD_BALANCE_ALGORITHM will change it for routes where it terminates TLS (default us leastconn).

More info on changing the internals of how haproxy works in the OCP 3.5 docs .
