Kairos 2.2.0 release

Kairos 2.2.0 has just been released, and we are thrilled to share the latest updates and improvements to the Kairos project. This release is a major release as reflect changes to internal core components and enhanced support for the ARM architecture.

What changed?

This release brings updates to the Kairos core components, including a substantial refactor of internal components and several bugfixes.

In order to enhance the user experience and reduce maintenance efforts the elemental cli and the kairos-agent functionalities were merged together. The kairos-agent now is responsible for the lifecycle of Kairos. This includes upgrades, setup, and delegating configuration to the specific providers that implement the specific configuration (k3s, for instance). The cloud-init stages can be run directly with the kairos-agent, and there is a --debug flag now to ease out troubleshooting. We also have renamed and moved user-facing commands of the Kairos CLI to kairosctl.

Besides, the Kairos agent now is capable to support multi-arch images, as such is now possible to specify container images during upgrades for different platforms within the same tag.

We consolidated our support for the ARM architecture, most notably:

  • Generic iso ARM images, that can be used for development or in VMs
  • Support for Nvidia AGX Orin!
  • RPI images now are shipping with LVM, and as such the oem partition is available as in the x86_64 flavors. Note: Reset is not working, we are addressing this into a patch release.
  • Add ubuntu to the available RPI images

We are working also on a pure, Alpine flavor, which is now independent from systemd. Stay tuned!
