An immutable Kubernetes
appliance, not a distro.

Ruckos boots from a read-only image; nothing to patch, nothing to drift, nothing open to attack.

Ruckos Linux is the OS that hosts your Kubernetes nodes and hosts your workloads — and it also runs the control-plane components, including the etcd database. With a single, focused use case it strips out the complicated, fragile configuration, maintenance, and security vulnerabilities of a general-purpose distro. It's designed to be as minimal as possible while staying practical, and it deploys anywhere you can run a modern Linux kernel.

  • API managed

Power-on to running cluster

Ruckos Linux is a hardened, immutable operating system that boots directly into a read-only kernel. Provision it with rctl.exe, the CLI, or with Nytro, the web UI — both drive the same declarative API, so the node registers itself, joins the Kubernetes control plane automatically, and is ready to schedule workloads in under 5 minutes.
