screenshot of command line first step - cat test.bu second step running butane --pretty --strict test.bu -o test.ign third step - cat test.ign (shows json formatted file with version 3.6.0) fourth step - ignition-validate test.ign (results in couldn't parse config: unsupported version)

Inspired by @bycx I started looking into CoreOS which seems like a good OS for my home cluster (immutable, more lightweight than Debian, easier to maintain).

I'm starting with a simple process - installing from flash drive and providing the installer with […]

If you have some #Fedora #CoreOS `testing` stream nodes check them to see if they have stuck updates. More info and workaround steps in lists.fedoraproject.org/archives/list/coreos@lis...

I Cannot SSH Into My Server Anymore (And That’s Fine) To kick off 2026, I had clear objectives in mind: decommissioning my trusty VPS and setting up its successor. Embracing a complete paradigm shift, I built myself a container-centric, declarative, and ...

Last week I went down a rabbit hole with #CoreOS, #Ignition, and #Quadlets while reworking my website deployment—and locked myself out of my server in the process.

I am looking for beta reader for a post describing in depth how I came to move my website infrastructure to containers hosted on Fedora #CoreOS, see github.com/lthms/tinker...

If you are curious, please reach out! I want to make sure it’s an interesting and instructive piece.

Major learning curve to use #fedora #coreos is how to create ignition file. #FCOS installation use that for installation configuration. There's no menu or wizard like other #linux distros.

Why? Because one of major goal of #FCOS is to enable easy mass deployment of similar configuration.

After […]

Now, #fedora is still my daily OS on my workstation (PC and laptop). On my servers, #centos had been my primary server distro, but changed to #rockylinux and #almalinux because #redhat policy changes.

There are some of my servers also use fedora #coreos aka #fcos and i love it.

Fedora CoreOS rebasing to Fedora Linux 43 Fedora Linux 43 was released today [1]. The Fedora CoreOS testing stream has been rebased and is currently rolling out. This update will come to the stable stream in a few weeks. As of Fedora 43 updates are now built via a container workflow [2] and exclusively shipped via the quay.io/fedora/fedora-coreos container registry. This means updates no longer exist in the OSTree repo at https://ostree.fedoraproject.org [3]. For other Fedora 43 related changes you can see the full list of Fedora ...

One of the nice things about bootc is that it enables you to have a stable base that can also be very up to date.

Why not use that to host a web server?

PoC: Leveraging Butane during Ignition boot Converting Butane to Ignition on Boot We’ve received anecdotal evidence over the years that the transpilation step where you must convert a Butane YAML configuration into Ignition JSON before staring your CoreOS instance is a pain for users to understand and implement. CoreOS developers also feel this pain at times. What if you could feed either a Butane YAML config or an Ignition JSON config to your instance and it would just do the right thing regardless?

Should we enhance @fedora #coreos / Ignition to be able to pass in Butane configs directly? Check out this demo and add some feedback here or in the tracker issue.
