SUSE Telco Cloud Documentation|Setting up the management cluster|Introduction

27 Introduction

 

The management cluster is the part of SUSE Telco Cloud that is used to manage the provision and lifecycle of the runtime stacks. From a technical point of view, the management cluster contains the following components:

  • SUSE Linux Micro as the OS. Depending on the use case, some configurations like networking, storage, users and kernel arguments can be customized.

  • RKE2 as the Kubernetes cluster. Depending on the use case, it can be configured to use specific CNI plugins, such as Multus, Cilium, Calico, etc.

  • Rancher as the management platform to manage the lifecycle of the clusters.

  • Metal3 as the component to manage the lifecycle of the bare-metal nodes.

  • CAPI as the component to manage the lifecycle of the Kubernetes clusters (downstream clusters). The RKE2 CAPI Provider is used to manage the lifecycle of the RKE2 clusters.

With all components mentioned above, the management cluster can manage the lifecycle of downstream clusters, using a declarative approach to manage the infrastructure and applications.
