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.
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
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_64flavors. 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!
