If you encounter a bug and something does not work, make sure you have done the following and check those boxes before submitting an issue - thank you!
- [ ] Never use different mysql|mariadb versions on the same `HOST_PATH_MYSQL_DATADIR` on existing database files. Different mysql|mariadb versions might upgrade/corrupt existing database files. If you have done that already, start with a different path of `HOST_PATH_MYSQL_DATADIR` (to an empty directory) and try again.
