quick question about data persistence ; usually in a dockerhub page you get the volume to bind in order to persist data when the docker is removed. But in this case it is not mentionned ? https://hub.docker.com/r/wurstmeister/kafka/
For exemple in the ches/kafka image : https://hub.docker.com/r/ches/kafka/
It is mentionned :

So my question is : What are the volume to bind inside the wurstmeister/kafka to persist data ? (Might be a dumb question :) )
Good day every one
