FAQ

Why do I fail to delete an ACK cluster?

Resource Orchestration Service (ROS) does not have permissions to delete resources that are manually added to an ROS stack. For example, ROS cannot release a virtual private cloud (VPC) that contains a manually added VSwitch. Consequently, the cluster deployed in the VPC cannot be deleted.

ACK allows you to forcibly delete clusters. If your first attempt to delete a cluster fails, you can forcibly delete the cluster and the ROS stack. However, when you forcibly delete a cluster, the ROS-created resources and the manually added resources are not released. You must manually release these resources.

An error message appears when a cluster fails to be deleted, as shown in the following figure.
The cluster fails to be deleted.
  1. After your first attempt to delete a cluster fails, choose More > Delete in the Actions column.
  2. In the dialog box that appears, you can view the resources that failed to be deleted. Click OK to delete the cluster and ROS stack.

    Note In the dialog box that appears, if you select Retain Resources, the ROS-created resources and the manually added resources are both retained. You must manually release these resources.
