#coreos — Public Fediverse posts

Now running #UniFi OS Server with Fedora #CoreOS on #Proxmox. Just one "terraform apply" command, from VM creation to service running. OS and Unifi Server are both auto-updating with zero manual maintenance.

Thanks to @moreentropy!

@moreentropy Nice! Another piece of hardware converted to @fedora #CoreOS

Can someone tell me why #bootc is a replacement for #ostree? It seems like a solid downgrade.

Ostree has better download semantics, while bootc literally... clones container layers. Ostree lets you create temporary and permanent overlays. Bootc asks you to "maintain" your own container image. The temporary overlay solution is to use sysexts overlays, which is far more restrictive.

There are many other points that I'm forgetting right now.

So why is ostree being sunset in favour of bootc again?

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.

Digital Sovereignty isn't just for nations!

Now that the desktop has reached The Final Shape we turn attention to our homelabs.

Been making great progress on this, we're at v .8. This one is boring. Knuckle just installs flatcar.

But we want cloud native magic so we're building "Bluefin Server" but not sure on the name. And it'll run flatcar, and in there your magical bootc factory runs and your bluebuild just worked ootb. And the Fedora one will come with coreOS, tekton, forgejo, konflux, etc.

A place for both - if we design the homeserver and desktop as one unified WHOLE, we could do a ton more stuff. The tech is already finished.

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?

@ercanbrack I can confirm this. Checked on my #Fedora 43 workstation.

But I'm still waiting for the next update of Fedora #CoreOS / #fcos.

Been trying to cook up a systemd-sysext for crowdsec + crowdsec firewall bouncer to extend the base flatcar container linux image. Surprisingly straightforward with the sysext bakery.

However, crowdsec needs a mutable folder where it can write stuff (e.g logs etc.). This defaults to /var/crowdsec/data. I can create the /var/crowdsec/data folder but when crowdsec attempts to create and write to the logs folder below this I see a permission error.

Am I missing something obvious? Anyone know how I can fix this?

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?

If you have some #Fedora #CoreOS `testing` stream nodes check them to see if they have stuck updates. More info and workaround steps in https://lists.fedoraproject.org/archives/list/[email protected]/message/ZMWF2EBO5ZBJE53MJFD75YID7XTNEGMB/

I've been wrangling with #fedora #coreos since yesterday to setup a minimal forgejo runner instance running in #podman. Although I've been working with Flacar Linux (the successor to the original CoreOS) before, it seems to behave a little bit different here and there (e.g. SELinux).

@mandrasch Ich denke digitale Souveränität kann nicht bedeuten, dass jeder ein NAS mit Nextcloud zu Hause hat. Das ist nicht resourcenschonenend und schwer abzusichern.

Scchau dir @netcup an. Ich empfehle eine ARM VM mit #Nextcloud AIO mit #Borgbackup zu #Hertzner #StorageBox.

Wenn du dich gut auskennst, nimm als OS #CoreOS und #Podman Quadlets for Nextcloud.
