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!
Docker really. If something goes bad, trash the container and start again without loosing your actual data.
Mostly Docker.
Portainer and plugging Docker Compose XML into Portainer stacks makes Docker stupid-simple. (personally speaking as a stupid person that does this)
Cloudflare tunnels for stuff people other than you might want to access.
Tailscale if it’s only you.
Reverse proxy & port forwarding for sharing media over Jellyfin without violating the Cloudflare Tunnel ToS.
Dokploy is a pretty easy web gui and is itself a docker container.
Makes it dead simple to manage multiple containers and domains. (Not for power users that need kubernetes level flexibility)
