Can/Should I share MariaDB across Docker services?

• Docker Compose

  Running a database container per service that needs it, would probably be the best option. More secure, easier backups, migration, updates, etc (especially if you use something like Docker Compose ). Of course different services may also require different MariaDB versions, another advantage. As others have mentioned, if your services don't do much, the database containers will idle and not consume a lot of resources. One case where you might want to use the same database container is if you have multiple services that work often (like web data scrapers, RSS feed aggregators, Usenet-related services).

  I was using MariaDB exclusively, but one of the software I use, Ghost, had compatibility issues with MariaDB and they announced that they would only support MySQL from now on... So I migrated some databases to MySQL, but I didn't migrate them all because I find MySQL to be resource intensive. 😕
