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.

Containers lower the bar since the developer doesn’t need to make their program work on every system - just the container’s system.

Price we pay for more programs. And they bring boons like read-only, rootless, limited capabilities, and constrained perf limits (esp if you use Podman with Quadlets).

And don’t feel trapped - the Dockerfile is a recipe to build that program. Probably want to do it in an LXC container since it’ll want to use /data for its data or something. But the LXC container can also be run as a user but the program thinks it’s root. Plenty of security abounds!

I think it’s worth the price and you’re not trapped. They’re trapped with you and your robust Quadlet files
