Hi!

I am an embedded systems guy so this is new territory for me. I want to be able to host my own userbase somewhere, mainly I just want to figure out how they work. But all i can find are closed solutions that have some amount of pricing or are obscured. I also feel like it'd be wrong to re-write something like this myself.

I've tried googling around a bit but keep getting similar results so I am assuming I am asking the wrong question. What I want: Ideally some kind of dockerized setup where a user can navigate to a website to create an account, which I can then query through php or some other API. Stuff like password reset or stripe would be nice but is secondary as that can most likely be added another way.

I found stuff like usernbase which seems interesting and even includes something like subscriptions, but I'd like to self host it and not rely on something like the AWS.

Ideally I want to get OAUTH2.0 to work as well, to learn how exactly it works.

Any pointers would be greatly appreciated!
