Kairos - Kubernetes-focused, Cloud Native Linux meta-distribution

The immutable Linux meta-distribution for edge Kubernetes.

With Kairos you can build immutable, bootable Kubernetes and OS images for your edge devices as easily as writing a Dockerfile. Optional P2P mesh with distributed ledger automates node bootstrapping and coordination. Updating nodes is as easy as CI/CD: push a new image to your container registry and let secure, risk-free A/B atomic upgrades do the rest. Kairos is part of the Secure Edge-Native Architecture (SENA) to securely run workloads at the Edge (whitepaper).

Kairos (formerly c3os) is an open-source project which brings Edge, cloud, and bare metal lifecycle OS management into the same design principles with a unified Cloud Native API.
