High Availability for the UDP Proxy
The UDP proxy's HA model is based on the keepalived virtual IP concepts. A VIP is designated to the N4 interface during the deployment. Also, a keepalived instance manages the VIP and ensures that the IP address of the VIP is created as the secondary address of an interface in one of the worker nodes of the K8s cluster.
The udp-proxy instance on this worker node binds to the VIP and assumes the role of the active udp-proxy pod. All udp-proxy instances in the other worker nodes remain in the standby mode.
