The command used to start the server:

java -jar -Xms1024M -Xmx2048M /path/to/forge.jar --gameDir /path/to/server_folder --nogui

How do I start a forge server with a custom gameDir option in the command?

 

How to replicate?

1. Create a ubuntu 22.04 docker image.

2. Install a 1.16.5 forge server. Latest or recommended version.

3. Start the server with the --gameDir option.
