| Keeping your OpenShift Container Platform HAproxy HA with Keepalived | |
| A typical OpenShift Container Platform deployment will have multiple master, app and infra nodes for high availability. In this case, there is no single point of failure for the cluster, unless you have a single HAproxy server configured. The following article will discuss how to configure keepalived for maximum uptime for HAproxy. In the vsphere on OCP reference architecture, [https://access.redhat.com/documentation/en-us/reference_architectures/2017/html/deploying_a_red_hat_openshift_container_platform_3_on_vmware_vcenter_6/] two HAproxy virtual machines are configured and the ansible playbooks set up keepalived using a virtual IP address for Virtual Router Rendundancy Protocol or VRRP. | |
| Load Balancer Options | |
| The load balancer will distribute traffic accross two different groups. HAproxy serves ports 8443 for the masters and 80, 443 for the infra nodes for the routers. The reference architecture provides a couple of different options f |
