How do you manage you DB in a docker environment? (sh.itjust.works)

Hello,

As the title suggests, how do you manage your DBs for docker services.

Do you spin a new DB for every new docker cluster or do you have a centralized DB that is accessible to the docker clusters.

What are the pros and cons of both method?

For the moment, I spin a new DB for every services as I feel it is easier to backup the service in case of a problem.

Same, exactly what I do. For the part about backups, there are tools that make it really easy. I'm using databasus for instance. Once I had set up a couple applications, adding a new db, user, and backup config took just a few minutes every time really. In the end figuring out how to backup every docker stack's individual DB sounds more complicated to me.

Edit: plus my first service hosted in this lab was my own matrix instance so I needed a solid DB, then it was already there so might as well use it.
