I'm running optaweb-employee-rostering in a dockerized Wildfly server, persisting data with MySql database running in a container too. The .war file is not built in sever's Docker image, it's manually deployed in it via Wildfly's admin interface. Every time container is stopped a restarted, the application rebuild sample data, deleting any data saved during usage, so that the final behavior is the same as ram based storage: the data is lost if the server stops.
Is there a way to avoid this behavior and keep saved data on server restart?
