What Can I Do If a Cluster Deletion Fails Due to Residual Resources in the Security Group?

When deleting a cluster, CCE obtains the cluster's resources, such as the elastic network interfaces (ENIs) or sub ENIs bound to a CCE Turbo cluster through kube-apiserver of the cluster. If the cluster is unavailable, frozen, or hibernated, the resources may fail to be obtained, and the cluster may not be deleted.

Symptom

The cluster cannot be deleted, and the following error information is displayed:

Expected HTTP response code [200 202 204 404] when accessing [DELETE https://vpc.***.com/v2.0/security-groups/46311976-7743-4c7c-8249-ccd293bcae91], but got 409 instead {"code":"VPC.0602","message":"{\"NeutronError\":{\"message\": \"Security Group 46311976-7743-4c7c-8249-ccd293bcae91 in use.\",\"type\":\"SecurityGroupInUse\",\"detail\":\"\"}}"}

Possible Causes

The cluster's security group has undeleted resources, preventing its deletion and causing the creation of the cluster to fail.

Procedure

  1. Copy the resource ID in the error information, go to the Security Groups page of the VPC console, and obtain security groups by ID.

  2. Click the security group to view its details, and click the Associated Instances tab.

    Obtain other resources associated with the security group, such as servers, ENIs, and sub-ENIs. You can delete residual resources. The sub ENIs will be automatically deleted.

  3. For a residual ENI, go to the Network Interfaces page and delete the ENI obtained in the previous step.

    You can search for the ENIs to be deleted by IDs or names.

  4. Go to the Security Groups page to confirm that the security group is not associated with any instance. Then, go to the CCE console to delete the cluster.
