I am running a Minecraft server (using Docker) on a physical server. So far, everything's working.
Now I would like to run a second server using a second Docker container, with a different configuration, but on the same physical server. The reason for this is that AFAIK a Minecraft server can only host one world with one configuration, and I'd like to have one server in creative mode, and another one in survival mode.
Now, I need to set up ports for those servers. Is it enough to map port
25565 to another port, and the client is then able to access it, if I provide the IP address / port combination? Or is there anything else I need to watch out for?
