Specification

Prerequisites

Quickstart completed

Usage

Create clusterClass and first cluster

1. Generate the ClusterClass and cluster manifests

   clusterctl generate cluster test-cluster \
       --kubernetes-version v1.29.1 \
       --infrastructure linode-linode \
       --flavor clusterclass-kubeadm > test-cluster.yaml
   

2. Apply cluster manifests

   kubectl apply -f test-cluster.yaml
   

(Optional) Create a second cluster using the existing ClusterClass

1. Generate cluster manifests

   clusterctl generate cluster test-cluster-2 \
       --kubernetes-version v1.29.1 \
       --flavor clusterclass-kubeadm > test-cluster-2.yaml
