Kamaji and Kairos

Run immutable worker nodes managed by Kairos, joining a Tenant Control Plane powered by Kamaji thanks to the kubeadm Kairos provider

Kairos Kubeadm provider OCI artefact (k8s v1.31.1)

Clone the kairos-io/provider-kubeadm repository, and build artefacts according to your needs.

For our use case, we're going to build on Ubuntu 22 LTS amd64 to install all the required packages for a Kubernetes v1.31.1 worker node.

• token
• API Endpoint
• role (with Kamaji acting as Control Plane manager, it's worker)
• optionally, any custom configuration
