I do some self hosting for my own projects.. if you want to and have the time an resources it is fun in a way. It is trivial to start with 1 thing so try it out. Probably your OS already has servers installed.

However it is my opinion that it is better, for the most part, for most people to use tools hosted externally. There are economies of scale. It would really be truely stupid for masses of people to all have their own little homelabs. And being an admin is a serious trade with a lot of skills and it is a time sink. And it is risky. If we are doing stuff online that we want to last, that is important, there are reasons to leave it to smarty pants nerds. Just like home maintenece or health care or hair cuts... there is a role for hobby DIY and a role for getting a pro.

If you cant parse the documentation to figure out how to set it up, you are not competant to do it. The software is not ready to be run by a person of your skill level. And im not saying that to be shitty to you; i looked at the requirements and i think it would be more than i have the time/knowledge to do. I have tried and failed for this reason at lots of things.

This is really complex project. Try something simpler Here is a list (simple to ultra complicated): https://github.com/awesome-selfhosted/awesome-selfhosted

There are a couple of selfhost(ed) communities on lemmy too
