Sean tells us about bootable containers and asks for our opinions on how he plans to use them with Kubernetes.
#bootablecontainers
You can thank `bootc`, `/usr/lib/bootc/kargs.d/`, and @fiftydinar for your new ability to include kargs in your native container image.
Just make sure to update with `bootc` instead of `rpm-ostree`.
Check it out!

Ah yes, nothing screams productivity like spending countless hours installing 53 different panels and 27 docks just to make your terminal look like a circa-2001 GeoCities page. 😎 Meanwhile, your bootable containers are out there actually doing *real work,* but sure, let's focus on choosing *the perfect shade of blue* for your desktop. 🖌️

I'm really exited about RHEL image mode that offers a method to manage RHEL in a container native way.
If you like to know how what it has to offer checkout my tutorial at: https://developers.redhat.com/articles/2025/03/12/how-build-deploy-and-manage-image-mode-rhel
Kennt ihr den RHEL image mode? Es ist eine der spannendsten Neuerungen in RHEL. Mehr dazu könnt ihr in meinem Blog erfahren: https://www.my-it-brain.de/wordpress/einfuehrung-in-den-rhel-image-mode/
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/

Bootable Containers are the future of Fedora Atomic Desktops and we presented that at @allsystemsgo.
Introduction by @cgwalters and Ben: https://media.ccc.de/v/all-systems-go-2024-266-bootc-generating-an-ecosystem-around-bootable-oci-containers
Then take a look at how we could use sysext's to improve the local layering story with @tormath1: https://media.ccc.de/v/all-systems-go-2024-313-waiter-an-os-please-with-some-sysext-sprinkled-on-top
And then finally dive into Trusted Boot with UKI and composefs with @jbtrystram: https://media.ccc.de/v/all-systems-go-2024-309-the-road-to-a-trusted-and-measured-boot-chain-in-bootable-containers

To be more precise, the updates are #atomic, while most of the system is #immutable, that is a term with a certain meaning in programming languages but people not used to it think "can't be modified".
BTW the new term (specific to the current #FedoraAtomic / #CoreOS) may be #BootableContainers when they will migrate to #bootc and I think it makes very clear to many people that it brings all the advantages of the OCI ecosystem
I will definitely be taking a look at the new #ImageMode deployment method Red Hat announced yesterday during Summit. It has potential for some really cool applications and deployment cases. I'm thinking of spending some time this weekend messing around with generating @centos and @fedora images!
