When using the “normal” teamspeak server, you can use the -mmdbpath
parameter to use a custom GeoIP database file (like maxminddb).
When using the docker version of the teamspeak server, I can mount the file by using volumes, but there is no enviroment variable to load the file (at least it is not documented on the TeamSpeak DockerHub page).
It would be nice if an environment variable would be added.
