Unbind a Cluster

This tutorial demonstrates how to unbind a cluster from the central control plane of KubeSphere.

Prerequisites

  • You have enabled multi-cluster management.
  • You need a user granted a role including the authorization of Cluster Management. For example, you can log in to the console as admin directly or create a new role with the authorization and assign it to a user.

Unbind a Cluster

You can unbind a cluster by using either of the following methods:

Method 1

  1. Click Platform in the upper-left corner and select Cluster Management.

  2. In the Member Clusters area, click on the right of the the cluster that you want to remove from the control plane, and then click Unbind Cluster.

  3. In the Unbind Cluster dialog box that is displayed, read the risk alert carefully. If you still want to proceed, enter the name of the member cluster, and click OK.

Method 2

  1. Click Platform in the upper-left corner and select Cluster Management.

  2. In the Member Clusters area, click the name of the member cluster that you want to remove from the control plane.

  3. In the navigation tree on the left, select Cluster Settings > Basic Information.

  4. In the Cluster Information area, click Manage > Unbind Cluster.

  5. In the Unbind Cluster dialog box that is displayed, read the risk alert carefully. If you still want to proceed, enter the name of the member cluster, and click OK.

    Note

    After you unbind the cluster, you cannot manage it from the control plane while Kubernetes resources on the cluster will not be deleted.

Unbind an Unhealthy Cluster

On some occasions, you cannot unbind a cluster by following the steps above. For example, you import a cluster with the wrong credentials, and you cannot access Cluster Settings. In this case, execute the following command to unbind an unhealthy cluster:

kubectl delete cluster <cluster name>
