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.
Not sure what works best in your case. I’m a Debian cat myself but I have been considering openbsd as a future option.
I’m a long time user of Debian myself too. No cutting edge fuzz, just a working, stable OS all of the time. What else do you need for a server? It always did the job.
But then I stumbled on FreeBSD, and man, that’s a server OS. Simple design and blazing fast. No Docker but I never liked it anyway. My Docker is called Jails and in my opinion is they’re superior. Service isolation on the next level.
On my laptop? Debian due to hardware and software support. And I’ll stick to that for now. I feel home on that distro.
I can’t say anything about OpenBSD as I never tried it but it sure is a perfect fit for a server as well depending on your needs and preferences. BSD just rocks!
I love Debian too. Could you tell me what you mean FreeBSD being a faster and better server OS? Is there such a difference in speed in operations?
TBH I’d run alpine VMs on Bhyve to get K8S running and that’s it.
My feeling is that there is. I think it all started with the speed I can login over ssh. Debian always seems to have a short delay but FreeBSD feels instant. When it comes to rating FreeBSD as a better OS for servers I may be biased as Debian has served me so well over the years. I was never a Docker fan but instantly liked Jails for isolating services. Then we have native ZFS support which simplifies my backup needs. A simple zfs send | zfs receive and you have an exact copy of your service instance on a remote node. Everything feels integrated and not stacked. Again, just a personal opinion.
OpenBSD has native limitations on hypervisors. Disabling default measures will lessen security, unfortunately.
