    You should replace -tcp-services-configmap with --tcp-services-configmap.

    refer to exposing-tcp-udp-services.

    Here there is a typo error where the args are --tcp-services-configmap, instead you are using -tcp-services-configmap.

    –tcp-services-configmap flag is used to specify the name of the ConfigMap containing the definition of the TCP services to expose. The key in the map indicates the external port to be used. The value is a reference to a Service in the form "namespace/name:port", where "port" can either be a port number or name. TCP ports 80 and 443 are reserved by the controller for servicing HTTP traffic.

    Further, the tcp value allows you to set a key configMapNamespace. So if you were to set this key only, then the flag would be used as per paramaters helpers.
