The HA proxy is an appliance that is deployed as an OVA. The HA proxy is used to route network traffic between Kubernetes pods and acts as load balancer as well. To enable workload management, networking must be configured. There are two options—NSX-T Data Center or vSphere Distributed Switch (vDS) networking with external load balancing. Currently, the HA proxy is supported and must be configured before workload management is enabled. Workload management cannot be set up without the HA proxy instance.
For requirements to enable networking, see https://docs.vmware.com/en/VMware-vSphere/7.0/vmware-vsphere-with-tanzu/GUID-B1388E77-2EEC-41E2- 8681-5AE549D50C77.html#GUID-B1388E77-2EEC-41E2-8681-5AE549D50C77.
To deploy the HA proxy and configure IP addresses, ensure that the OVA is available at the local or content library. To find the location from which to download the OVA, see the following VMware knowledge base article: https://kb.vmware.com/s/article/80735?lang=en_US&queryTerm=80735.
Note: To deploy the appliance with 2 NICs, that is, a management and single workload network, select Default; to deploy the appliance with 3 NICs, that is, a management network, a single workload network, and a dedicated front-end network, select Frontend Network.
