Running `keepalived` as a DaemonSet will allow managing floating "virtual" IP addresses for Kubernetes services with configured external IP addresses. The main services we want to expose outside the cluster are _ingress-nginx_, Mosquitto, and RabbitMQ. The `keepalived` cluster will negotiate using the VRRF protocol to determine which node should have each external address. Using the process tracking feature of `keepalived`, we can steer traffic directly to the node where the target service is running.
