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!
Programming is generally not needed when self-hosting. At best you might learn Ansible, Puppet, Salt, or Terraform, but that’s for advanced scenarios (e.g. easily shifting the workloads between machines or into the cloud).
Learning the ins-and-outs of containers will get you the biggest return on investment. They’re not strictly necessary but most tools will expect that is the common use-case and the community won’t be as much help. Until you know more about containers I would also recommend Docker over Podman. It has a few more “conveniences” than Podman and orgs like LinuxServer will target Docker as the engine.
