This allows you to map one port to multiple minecraft servers via domains
Find the latest docker image at https://github.com/rodiconmc/RodiForwarder/packages
Set the environment variable LISTENPORT to the port, usually 25565
Set the environment variable RODIFORWARD like this:
[DOMAIN1];[HOST1:PORT1] [DOMAIN2];[HOST2:PORT2] [DOMAIN3];[HOST3:PORT3] etc...
For example, the environment variable
RODIFORWARD="alpha.rodiconmc.com;10.0.0.1:25565 beta.rodiconmc.com;10.0.0.2:25565"
Would mean that users connecting to alpha.rodiconmc.com would be forwarded to 10.0.0.1:25565, and users connecting to beta.rodiconmc.com would be forwarded to 10.0.0.2:25565
