-We provide a flag (such as `create-clusterproperty-not-exist`) to tell Karmada whether to create `id.k8s.io ClusterProperty` when it does not exist in the Kubernetes Cluster. During the cluster joining process, Karmada will look for if the kubernetes cluster has defined the cluster identifier by `id.k8s.io ClusterProperty`. If so, we just take the `id.k8s.io ClusterProperty` value as cluster id; otherwise, when the `create-clusterproperty-not-exist` flag is true, we'll just use kubernetes cluster's `kube-system` namespace uuid to create `id.k8s.io ClusterProperty`, when the `create-clusterproperty-not-exist` flag is false, we refuse to join the cluster into Karmada.

 Just as phase one, we need to use the same check to ensure the uniqueness of the cluster in Karmada.
 
 Again, this check can be performed in two places: one in the join phase and the other in the Cluster object creation phase. We can choose one of them.
 
-When a cluster is removed from Karmada, `id.k8s.io ClusterProperty` created in the cluster do not need to be deleted.
