what will be my next server operating system (Fedora Server, Fedora CoreOS, NixOS), your experience and opinion

cross-posted from: lemmy.world/post/14160134

I want to reset my server soon and I’m toying with the idea of using a different operating system. I am currently using Ubuntu Server LTS. However, I have been toying with the idea of using Fedora Server (I use Fedora on my laptop and made good experiences with it) or even Fedora CoreOS. I also recently installed NixOS on my desktop computer and find the declarativeness pretty cool (but I’m still a complete beginner) and could imagine that it would fit well into a server setup.

I have quite a few services running on my server, such as Nextcloud, Conduit (Matrix), Jellyfin, etc. and all in containers. I would also rather not install programs without containers, because 1. compose is super easy to maintain and set up, 2. it remains very clear with containers (and compose) and 3. I believe that containers are more secure. But since I also want to make the services inside the containers available, I currently have Nginx installed as a reverse proxy (not in the container, but on the system) and always create certificates with certbot so that I can use HTTPS encryption.

In the paragraph above I actually described exactly the use-case of Fedora CoreOS, but I have no experience with the system and how it works. That’s why I’m still a bit hesitant at considering the OS at the moment. I can imagine that NixOS with its declarative nature seems well suited, since, as I have heard, you can configure containers as well as Nginx and with Nginx also https certificates declaratively. But I could also use a base system like before (Fedora Server or Ubuntu Server) and simply install podman, nginx and certbot and manage everything that way.

Have you had any experience with Fedora Server, Fedora CoreOS, NixOS or a completely different operating system for servers and what are/were your impressions with this setup? Or do you just want to share your knowledge here? I would be delighted.

flashgnash,

Nixos is great for self hosting. The declarative part is obviously very useful but people have talked to death about that

Have nixos on my pi, to install and configure nextcloud, I just paste in a block to my config, rebuild, and it’s up and running

Most things seem to have built in nix options for them so there’s super easy to install and configure, no faffing around with having to add ppas, set things up as services, spend any amount of time remembering what you have installed

Sad to have to use Debian instead on my pi 5 because nix wasn’t ready when I got it

Firstly, I don’t think Docker is intended to be used as a security layer. I could be wrong, but I think it’s relatively easy to escape the sandbox. Although that might be different nowadays.

Anyway, I recently switched from Debian to NixOS for my server and it’s so much nicer. Being able to use a single language for configuring everything all in one place is so nice. If I want to try something new, I can just throw maybe 30 lines in a config and it’s there. If I don’t like it, then I can remove that config and it’s gone. Most services you’d want to run on a server are available in the package manager, and many have rather sensible defaults.

The only headache for me was the lack of documentation (especially with flakes). There’s also a learning curve with the Nix language itself.
