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 and usually sane developers allow you to specify external mysql instances.
Delving into the politics many view docker as a standalone system that shouldn’t need external items so they leave their db internal. Which goes against having configurations external.
But then you have external databases that you need to know enough to setup ahead of time to allow the docker to use and now I gave myself a headache
