ClusterAPI Introduction

Cluster API is a platform agnostic way of managing physical resources (i.e. VMs) using Kubernetes.

This provides a nuber of advantages including:

• Familiarity to experience K8s admins, as nodes act similarly to pods…etc.

• Tooling which directly supports Openstack, including resource creation and management.

• Support and fixes for newer Kuberenetes versions without waiting for Openstack upgrades.

The Kubernetes image provided is based on upstream’s Ubuntu image, which has been forked to comply with UKRI security policy here.

Unlike Magnum, the Kubernetes version supported is completely decoupled from Openstack, with upstream typically supporting the N-1 major version (where N is the latest release).
