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.

The last thing I want is database corruption. That is why I "docker compose down" before I make a backup then "docker compose up" when the backup is complete. Is that not good enough? Do I have to do something else?

Yes that's good enough! Sorry I missed your statement about shutting down first. To clarify I leave mine running since a dump can recover if it gets corrupt.

Basically my backup contains the database and the SQL dump (or equivalent) - that way I don't need to shutdown the service.
