Trying to add the network via the launcher args doesn’t seem to work at all.

Manually connecting the network with _network connect_ works but doesn’t register the host name of the discourse service with dockers name resolution system so the mail server hostname lookup (ping my\_forum) fails. So I am back to square one - annoying that a simple docker network config is proving so tricky with discourse.
