Importing an Hive provisioned OpenShift cluster

You can use the scripts available at applier-samples-for-acm to ease the import process.

Prereq

Creating a Hive ClusterDeployment

For more information about Hive ClusterDeployment refer to https://github.com/openshift/hive

ManagedClusterController action

ManagedCluster Import Controller

When the first ClusterDeployment is created along with managedcluster and klusterletaddonconfig, the controller will call the applier to deploy the common parts of the klusterlet install manifest. This includes the namespace, service account and cluster role binding that is needed by the klusterlet operator.
When managedcluster is created, the controller will create klusterlet on the managedcluster.

Kusterlet addon Controller

When klusterletaddonconfig is created, klusterlet-addon-controller will create klusterlet addon on the corresponding Hive ClusterDeployment.
