Project Lightning Talk: Kairos: Immutable OS and Lifecycle Management for Kubernetes Fleets - William Rizzo, Mirantis
Kairos is an open source, immutable Linux OS for managing fleets across public cloud, on-prem, and edge environments. It can be built on familiar distributions like Ubuntu, Fedora, and openSUSE, or run with Hadron, a minimal Linux focused on upstream alignment and the needs of image-based immutable systems.
Kairos works with or without Kubernetes. It supports lightweight distributions such as k3s and k0s, while lifecycle operations are handled by the Kairos Operator, enabling full node upgrades directly from Kubernetes.
This session highlights recent project updates and introduces Kairos CAPI, our implementation of the Kubernetes Cluster API for provisioning and managing Kairos nodes using standard Kubernetes workflows.
With features like trusted boot, atomic upgrades, rollbacks, and factory reset, Kairos offers a consistent, portable way to manage distributed systems.
