I have one stack (zookeeper) that has a 3 container Zookeeper service.
I have a second stack (vms) that has a LoadBalancer in it that is linked to the zookeeper stack and service.
I want to change the hostname of the LB Agent container so that other services in the vms stack can find the loadbalancer by host name. So i used the ‘o.rancher.container.hostname_override : container_name’ label with the LB Agent but it seems to be ignored and the LB AGent container still gets a random hostname.
Docker-compose is below.
NB I am using the latest rancher version and docker 1.9 on centos 7 hosts
