Create IBM VPC Cluster Using ClusterClass

Preface

• To deploy IBM Cloud VPC workload cluster using ClusterClass, create a cluster configuration from the clusterclass-template.
• The clusterclass-template will use ClusterResourceSet and will create the necessary config map, secret and roles to run the cloud controller manager
• The flags EXP_CLUSTER_RESOURCE_SET and CLUSTER_TOPOLOGY need to be set to true.

A comprehensive list of IBM Cloud VPC Regions and Zones can be found here
