Honestly I think it’s a great way to get into self-hosting without having to worry too much! I don’t have any one specific guide to point you towards. I just got started a few weeks ago myself, and mostly brushed off some old skills I’d known from other projects and doing a LOT of searching of videos and posts and articles and just figuring things out as I went. So the best I can do is tell you some topics you’re going to want to learn about.

Assuming you’ll want to start small and easy (not needing to expose anything to the internet, just local area network stuff), I recommend you search up the following topics:

• Linux commands (if you don’t know them already)
• Running a virtual machine (if you don’t have some hardware lying around that you can use to run as your ‘server.’ Old laptops are a fantastic starting point if you do. But if not you can definitely experiment with a VM on your PC!)
• Docker & Docker Compose (in that order if you don’t find some two-in-one resource)

That should give you enough to start toying around and trying things out. And once you start doing that, you start unearthing what you don’t know and that’ll point you towards the next thing you need to learn. :)
