 * `DB_DUMP_INCLUDE`: names of databases to restore separated by spaces. Required if `SINGLE_DATABASE=true`.
 * `SINGLE_DATABASE`: If is set to `true`, `DB_DUMP_INCLUDE` is required and must contain exactly one database name. Mysql command will then run with `--database=$DB_DUMP_INCLUDE` flag. This avoids the need of `USE <database>;` statement, which is useful when restoring from a file saved with `SINGLE_DATABASE` set to `true`.
 * `DB_RESTORE_TARGET`: path to the actual restore file, which should be a compressed dump file. The target can be an absolute path, which should be volume mounted, an smb or S3 URL, similar to the target.
