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.
Individually. If the app requires a DB, I put it in the compose file. This simplifies both backups and migrations. My tooling for backups has a pre and post script I can customize on a per app basis so I just have the pre do whatever *dump for that DB and the post clean it up (backup takes a tar of the folder).
