-# This script is the entrypoint to the image.
-# Supports version 3 daemonsets
-#    $1 is the daemon to start.
-#        In version 3 each process has a separate container. Some daemons start
-#        more than 1 process. Also, where possible, output is to stdout and
-#        The script waits for prerquisite deamons to come up first.
-# Commands ($1 values)
-#    ovs-server     Runs the ovs daemons - ovsdb-server and ovs-switchd (v3)
-#    run-ovn-northd Runs ovn-northd as a process does not run nb_ovsdb or sb_ovsdb (v3)
-#    nb-ovsdb       Runs nb_ovsdb as a process (no detach or monitor) (v3)
-#    sb-ovsdb       Runs sb_ovsdb as a process (no detach or monitor) (v3)
-#    ovn-master     Runs ovnkube in master mode (v3)
-#    ovn-controller Runs ovn controller (v3)
-#    ovn-node       Runs ovnkube in node mode (v3)
-#    cleanup-ovn-node   Runs ovnkube to cleanup the node (v3)
-#    cleanup-ovs-server Cleanup ovs-server (v3)
-#    display        Displays log files
-#    display_env    Displays environment variables
-#    ovn_debug      Displays ovn/ovs configuration and flows
