The Docker Compose docs suggest using a separate override
configuration file for production-specific settings, but
it is not obvious how to feed this to `docker stack deploy`,
which only supports a single Compose file as input. Thus,
we now describe how to do this by merging the configuration
files with `docker-compose config`.
