## Usage against an existing database
If you start your `%%IMAGE%%` container instance with a data directory that already contains a database (specifically, a `mysql` subdirectory), no environment variables that control initialization will be needed or examined, and no pre-existing databases will not be changed. The only exception is the non-default `MARIADB_AUTO_UPGRADE` environment variable, that might cause `mysql_upgrade`/`mariadb-upgrade` to run, which might change the system tables.
