Self Host Change Default from MySQL to MariaDB

[SyberSin]

Hello,

First off thank you for building this as its much needed in the space, but it has been a nightmare to self host with no luck so far, I'm hoping somebody can help me out.

I'm very close to getting it working except the database migration is looking for a mysql docker instead of mariadb docker.

I already have a docker instance of maria, redis, mongo, etc running on my unraid server and I want to use those. How can I change the migration docker variable from mysql to maria?

The logs keep saying nc: bad address 'mysql' (If I install a mysql docker it works, but I'm trying to use maria instead.)

This is my new updated docker compose for unraid using the external service dockers.

The DB_HOST variable is set to the correct maria docker but it appears it is not using that variable for the migration, by default it looks for mysql.
