Where do I learn how to set up this sort of stuff? Trial and error? I kinda never need it for personal projects (so far), which always leads me to forget this stuff in between jobs kinda quickly. Is there a decent book?
If you want to learn it the best way is probably to come up with a personal project idea that requires it specifically? Idk how much you'd get out of a book but you could always do a side project with the specific goal of doing it just to learn a particular stack or whatever
