Corium is an immutable, container-native Linux distribution that boots directly into a Kubernetes node. Pick where to start.

Run a node

Quick start takes you from a published image to a working Kubernetes node in four steps. If you already know where the node will run, which install guide points at the page for your target.

Understand the model

Concepts explains the filesystem contract, what happens on first boot, and why the operating system is a container image. Read it once and the rest stops being surprising.

Look something up

Configuration specifies every field of the corium: schema. cctl covers every command of the management CLI. Examples has a complete, annotated document for each common node shape.

When it does not work

Troubleshooting indexes failures by what you observe, across every install path.
