Talos Linux: One (Immutable) OS to Rule Them All
summary
Talos Linux is an immutable, minimal OS built in Go with a hardened kernel, no SSH or shell and all management over a gRPC API secured by mTLS. Demo boots a five-node OpenStack cluster and a local two-node Podman cluster, successfully bootstraps etcd and K8s control plane, and shows upgrading a node from v1.73 to v1.74 and a fast rollback. Images are signed, reproducible squashfs artifacts (~80MB) and the system uses machined and talosctl to coordinate drains, upgrades and self‑healing.
