  kubectl -n kubesphere-system edit clusterconfiguration ks-installer
  

• Log in to the KubeSphere web console as admin, click Platform in the upper-left corner and select Cluster Management, and then go to CRDs to search for ClusterConfiguration. For more information, see Enable Pluggable Components.
