clusteradm init
# Request a managed cluster to join the hub
kubectl config use-context <managed cluster context> # kubectl config use-context kind-managed-cluster
clusteradm join --hub-token <token> --hub-apiserver <api server url> --cluster-name <cluster name>
# Accept the managed cluster request on the hub
kubectl config use-context <hub cluster context> # kubectl config use-context kind-hub
clusteradm accept --clusters <list of clusters> # clusteradm accept --clusters c1,c2,...After each above clusteradm command, the clusteradm will print out the next clusteradm command to execute which can be copy/paste.
