You need a bit of help from the completion function in
question to do this.  The feature in question is "services": I just
looked at the docker completion and it does support this.

You'll need to do something like

compdef _docker mydockerwrapper=docker_service_complete_ls_filters

where the thing on the right of the "=" is an appropriate docker
completion function without the "_" (search for _$service for the code
in _docker supporting this).
