k3s-rancher-autoregister

Use Case

This is a mockup of a self registering K3S cluster in Rancher. The self-registering is done via the Rancher API and Shell scripts inside a (auto deployed) Pod, running in the local cluster.

This mockup is used for SUSECON DIGITAL 2021 together with our partner OpenNebula Systems showcasing a new approach for the far edge.

Warning

This is not fail-safe and production ready. It is an mockup for showcasing possibilites. In production we run those automations with a different approach.
