#fedoracoreos — Public Fediverse posts

Na razie pełni u mnie jedną rolę, ale powinny dojść kolejne. Jest to kolejne #Zabbix Proxy w mojej Zabbix Proxy Group. Co w przypadku faila innego komputera na którym hostuje Proxy (3xVM z #fedoracoreos) nadal będę miał dostępny monitoring.
Znając jednak ograniczenia dyskowe i RAM odrzuciłem kontenery i VM na rzecz natywnych pakietów -- tutaj mam najnowszego Debiana 13.

Question for the audience:
Yesterday I mentioned rebuilding my #homelab on upstream #Linux distros for #container workloads. Now I'm trying to decide between two solid options: #bootc or #Fedora CoreOS.
Both have their strengths. I'm curious where you land and why.

Which would you choose?

Pobawiłem się jeszcze chwilę i okazuje się, że #zincati pozwala na ustalenie okna serwisowego, co chętnie zaaplikowałem do swojego modułu. No przyznam szczerze, jeszcze nigdy ustawienie okna patchingowego nie było dla mnie tak proste :-). Ustawiłem sobie okno w weekend, ale każde #zabbixproxy ma patching innego dnia.

Pierwszy update kontenerów i samego systemu za mną #FCOS
Update systemowy odbył się automatycznie, bez żadnych problemów, jedynie dostałem alarm z Zabbixa, że host został zrestartowany.
Dzisiaj miałem update #zabbix proxy do 7.0.27. Rano się obudziłem i już klaster pracował na nowej wersji obrazu. Bez żadnych dodatkowych tooli.

@irfan I use Proxmox with Opentofu. I have my own modules: https://codeberg.org/cichy1173/cichyform

I mostly see VMs as stateless machines so I configure them only via cloud init. That's why I am moving to #fedoracoreos for simple VMs with containers.
But if you want to apply configuration on living hosts then Ansible will be better (you can combine both tools actually)

Fedora CoreOS zapowiada się na system operacyjny pod #selhosting który gdzieś wpisuje się w moje podejście do maszyn wirtualnych, czyli pod ciągłe tworzenie i ich usuwanie.
Udało mi się dostosować moduł #Terraform pod użycie CoreOS w Proxmox i pierwsza VM służy jako #zabbix proxy. #Butane przypomina #cloudinit co bardzo mi się podoba.

Ktoś może tutaj korzysta z CoreOS?

Introducing Chilly Willy Agent!

It provisions a private Woodpecker CI agent on Hetzner Cloud:

- IPv6-only by default (NAT66, optional DNS64 for IPv4-only upstreams)
- Fedora CoreOS + Podman runtime
- ./chilly-willy-agent wrapper plus make targets, all hitting the Hetzner Cloud API via curl
- Image-pin enforcement, optional firewall, multi-agent

Built primarily for Codeberg CI. Apache 2.0 licensed.

There was this lady in the coffee shop this morning with a bag her 10 yr old daughter made that had some art on it that reminded me of the CoreOS logo. What do you think?

Fedora CoreOS :coreos: is a great container first server distro.

I've enjoyed the experience, starting from, creating the igntion file for install, right through to setting up podman containers for my services.

I now have

*Opencloud
*Caddy reverse proxy
*a ejabberd xmpp server
*Pihole
*Immich
*Jellyfin Media server

all running using podman quadlets with Vaultwarden and possibly Joplin to come.

Fedora CoreOS 43 Test Days are happening from Sep 22-26!

There will be a virtual session for folks to ask questions on Monday September 22 from 10:00 AM - 11:30 AM EDT (2:00 PM - 3:30PM UTC).

Consider helping out if you're able. :)

The advantage of CoreOS is that it updates itself.
The disadvantage is that it updates itself.

We had a problem with a client's CoreOS machine and before I could get to fix it, the machine had magically updated and fixed itself.

With Allison, I presented at FOSDEM how we can combine UKI, composefs and containers to build a fully signed boot chain. The slides and the recording are now available: https://fosdem.org/2025/schedule/event/fosdem-2025-5191--signed-sealed-and-delivered-with-ukis-and-composefs/

This is how we are planning to bring boot chain integrity to Bootable Containers.

This is a follow up on the initial work that we presented last year at @allsystemsgo: https://cfp.all-systems-go.io/all-systems-go-2024/talk/HVEZQQ/

Help us test Fedora IoT and Fedora CoreOS for the release of Fedora 41!

If you're familiar with Fedora Atomic Desktops, then these editions will not seem so different aside from the server use case.

Both test days are running from today, Oct 7 to Friday, Oct 11.

Update: Show will be rescheduled due to conflicts

Join us today at 5pm EDT (9pm UTC) for an update on the atomic world of Fedora on the Fedora Podcast! @siosm will be explaining what bootc is, how it relates to rpm-ostree, and how it relates to the *future of desktop Linux.*

Bootc is basically the next generation of rpm-ostree. Here's an early look at bootc from someone who happened to start looking into Fedora CoreOS at the same time as bootc was announced. It's an organic exploration of both!

Say hello to @containertoolbx, the Mastodon account for Toolbx!

If you use Fedora Atomic Desktops or Fedora CoreOS, this may be a neat account to follow as it's what we use to manage containers - an important part of how to use this kind of system.

Folks that are using #butane for with #fedoracoreos or #flatcar how do you handle secrets in the configuration?

I'm looking at the idea of removing the config after initial boot or some other option.

One route would be to use single use secerts (which work for say #tailscale which supports them) but not for others

#fedoracoreos is a bit of game to deploy on cheap Hetzner and OVH VPSs and I don't like having to embed an ignition file that includes all my container setup.

So I'm working on an ansible role that will install python then add #podman quadlets and supporting files and directories.

This makes a really nice auto-updating container host.

Messing around with #FedoraCoreOS and so far it’s not bad but I’m a bit lost with the ignition files. Got a system online but if I want to add new services in the future should I just create the systemd files? Make a new ign file and “reinstall?”

How do I monitor or manage system updates?
