[erlang-questions] how: Simple distributed Erlang in docker containers

Since the original message has been removed it is difficult to explain 
what I mean with undocumented. But interested parties can look it up. 
Especially the "Name" argument, that included an IP address. The 
resulting behaviour is very useful if the computer has been configured 
in a way where Erlang/OTP can not find out the fully qualified host 
name. But I have not seen this documented.
