FAQ

The configuration files are usually in the same folder as the server jar, does persistence also include jar?

No, the persistence in volume, only includes the files ops.json, banned-*.json, whitelist.json, server.properties and the map folder.

Where can I find more information about custom settings?

The variables are the same as the server.properties file but in uppercase and changing the middle dash (-) by underscore (_), and you can find more information on this page.
