Hey there, I thought about starting my own Lemmy instance, yet I'd really like to use my already running MariaDB server for the database. I haven't found anything in the docs (might be me though). Is that possible or will I have to set up Postgresql?

If the application doesn't say anything about MariaDB or MySQL then it won't work. The SQL statements are different enough that there needs to be an explicit support.

You could contribute and add support, but that might be a bit of work.

Also the glory days of MySQL are over. MySQL started with goal to be fast, and placed correctness as an afterthought. Meanwhile PostgreSQL placed correctness as the most important goal. As time passed, PostgreSQL made many speed optimizations, while MySQL was forced to replace fast MyISAM engine with slower but more correct InnoDB, but the old design decisions still cause issues. As an SRE I've seen multiple times where MySQL and MariaDB also corrupted its own data.

I actually don't know your reasons to still sticking with it, but if you can I would recommend to give PostgreSQL a try it is much better experience for developers as well as for operations. There's a reason that less and less apps support MySQL/MariaDB.

Currently only Postgres is supported. However internally it uses the Diesel middleware, so I think it would be feasible to add MariaDB support in the future.

Possible, but I don't see it happening. Postgres provides functionality that MySQL/MariaDB don't, so if a lot of that functionality is used, the primary devs probably aren't going to want to take on the extra overhead of maintaining and testing it. In those cases, it would require additional rewriting on the Lemmy side to make it work seemlessly. A fork could likely do it, though.

@Jamie @poVoq best thing about PostgreSQL is PGAdmin4 since it supports OAuth2.

I’ve been working with fethiye tour lately. I’m frankly kind of shocked at how well documented the API is and how well it all works. And it’s mostly open. I haven’t done anything with ESP32 Cams I bought, yet. No idea what is possible there or where to start.

Commenting so I can figure this out too. Have you gotten it to work in docker without ansible? I only want to run this is a single docker server.

I’m running my instance fully in docker and only use docker compose

Would you mind sharing your docker yaml with me? Please?
