David Kirwan The ELB in front of the masters only comes into play for api/console access. The setup won't have any effect on the capabilities of the applications. If the only other load balancer is an ALB, then that must be fronting the apps running on the compute nodes. An ALB is capable of supporting Websockets; however, I don't know what all needs to be done in order for it to play nice with OpenShift. If you don't have a specific requirement which depends on using an ALB, I think you'd be better off mimicking what OSD does. i.e. Classic ELB, Layer 4 listeners, Proxy Protocol enabled, and SSL certificates installed on the routers in OpenShift
