Meet Kairos, an o-s project building the immutable Kubernetes edge
summary
Kairos converts any Linux container image into a bootable ISO and an immutable OS with active/passive partitions, TPM disk encryption, and a recovery partition; it bundles k3s, a VPN overlay and kube‑vip so a three‑node HA control plane plus workers comes up from network‑booted ISOs (demo shows five VMs; claim of deploying ~20 nodes in under 15 minutes). Upgrades are image swaps, configuration is cloud‑init style, and cluster bootstrap uses peer‑to‑peer gossip and a distributed ledger for self‑coordinated bootstrap; Intel and Facebook contribute.
