Okay, here's what i did...

In the obico-web container, i dumped the database:

nerdctl exec -it obico-web bash
./manage.py dumpdata > /data/backup.json

Then i created a MySQL (actually MariaDB) user and database and updated the .env file:

DATABASE_URL=mysql://obico:<redacted>@172.17.0.1:3306/obico

and restarted the obico-migrate container.

In theory, this would the create the DB schema in the MySQL DB and all i would have to do then would be import the data again, via:

nerdctl exec -it obico-web bash
./manage.py loaddata /data/backup.json

... and of course afterwards restart all other containers to switch to the new DATABASE_URL.

But unfortunately the image i'm using (thanks @gabe565) does not include the MySQLdb module:

May 20 17:24:31 hades nerdctl[2555010]: Did you install mysqlclient?

Could you guys maybe add mysqlclient to the requirements.txt, so that Gabe's images would be rebuilt with it?

You can set the DATABASE_URL in .env. We are using postgresql in prod so it at least takes postgres. https://github.com/TheSpaghettiDetective/obico-server/blob/release/docker-compose.yml#L28

Feel free to test other db flaors and lmk how it goes. I'll close the issue for now

Please open a PR for it. Adding the dependency is easy but testing and making sure it works entails a lot more work. This is something I hope you can do as part of the PR.

I managed to build an image with mysqlclient, but it looks like MariaDB doesn't quite like the migrations:

So the main problem is:

MySQLdb._exceptions.OperationalError: (1060, "Duplicate column name 'notification_enabled'")

from https://github.com/TheSpaghettiDetective/obico-server/blob/release/backend/app/migrations/0064_notificationsetting.py

The PR would be this one: #955

from obico-server.
