What skills are needed to self host without too many headaches? (lemm.ee)

For this new year, I’d like to learn the skills necessary to self host. Specifically, I would like to eventually be able to self host Nextcloud, Jellyfin and possibly my email server too.

I've have a basic level understanding of Python and Kotlin. Now I'm in the process of learning Linux through a virtual machine because I know Linux is better suited for self hosting.

Should I stick with Python? Or is JavaScript (or maybe Ruby) better suited for that purpose? I'm more than happy to learn a new language, but I'm unsure on which is better suited.

And if you could start again in your self hosting journey, what would you do differently? :)

EDIT: I wasn't expecting all these wonderful replies. You're all very kind people to share so much with me :)

The consensus seems to be that hosting your own email server might be a lot, so I might leave that as future project. But for Nextcloud and Jellyfin I saw a lot of great tips! I forgot to mention that ideally I would like to have Nextcloud available for multiple users (ie. family memebers) so indeed learning some basic networking/firewalling seems the bare minimum.

I also promise that I will carefully read the manuals!

That's an excellent question.

If I were to start over, the first thing that I would do is start by learning the basics of networking and set up a VPN! IMO exposing services to the public internet should be considered more of an advanced level task. When you don't know what you don't know, it's risky and frankly unnecessary.

The lowest barrier to entry for a personal VPN, by far, is Tailscale. Automatic internal DNS and clients for nearly any device makes finding services on a dedicated machine really, really, easy. Look into putting a tailscale client right into the compose file so you automatically get an internal DNS records for a service rather than a whole machine.

From there, play around with more ownership (work) with regard to what can touch your network. Switch from Tailscale's "trusted" login to hosting your own Headscale instance. Add a PiHole or AdGuard exit node and set up your own internal DNS records.

Maybe even scrap the magic (someone else's logic that may or may not be doing things you need) and go for a plain-Jane Wireguard setup.

For sure use Tailscale for VPN. They have apps for iPhone, Android, macOS, and Linux, so setting up your own personal network will be easy. Hosting on the real internet is definitely advanced and not always necessary.
