Is it possible to have just one DB across all services (lemmy.zip)

I'm pretty new to the self hosting thing but I'm enjoying it a lot and want to go a bit further down the proverbial rabbit hole.

I'm looking at a bunch of services and they all require a DB, usually a MySQL DB. It seems counterintutitive to have 20 MySQL databases each in its own Docker container. So is there a way to have one DB across most of my services? (I realize that Nextcloud and other bigger items should have a dedicted DB.)

How would I set up a shared DB in a docker-compose file?

Yes, you can.

Without going into specifics, you need to share the network of your DB stack with the stack of the client containers.
