+## Database
+
+The app and the RTE connect to MySQL as `ansibleforms` (`MYSQLDB_USER` in `.env`), with all rights on the `AnsibleForms`
+schema and none elsewhere: a hole in the app then stays a hole in its own data. Root (`MYSQLDB_ROOT_PASSWORD`) is for MySQL.

+create the user once, with the password you set in `MYSQLDB_PASSWORD`, before you start it with this `.env`:
+
+```bash
+docker compose up -d mysqldb
+docker compose exec mysqldb mysql -uroot -p -e "CREATE USER 'ansibleforms'@'%' IDENTIFIED BY '<MYSQLDB_PASSWORD>';
