Doc Type: Bug Fix
Doc Text:
The OpenStack Director previously configured HAProxy load-balancing with roundrobin instead of source balance, which resulted in sticky sessions failures. After this fix, the Director uses source balance for load-balancing in the HAProxy configuration, and sticky sessions run as expected.

Description Marius Cornea 2018-11-30 18:44:05 UTC 
Description of problem:
Currently the haproxy loadbalancer set by TripleO uses balance roundrobin. According to this Openshift HA configuration example[1] it uses balance source for both the API and the router backends. This way we ensure that all traffic from a user’s session goes to the same node(sticky sessions).
