Chapter 5. Configuring client connections
Clients for the AMQ Broker on OpenShift Container Platform image must specify the OpenShift router port (443) when setting the broker URL for SSL connections. Otherwise, AMQ Broker attempts to use the default SSL port (61617). Including the failover protocol in the URL preserves the client connection in case the pod is restarted or upgraded, or a disruption occurs on the router.
... factory.setBrokerURL("failover://ssl://<route-to-broker-pod>:443"); ...
External clients do not support HA.
