How Can I Check Whether a Network Interface Is Used by a Cluster?

Scenario

For CCE Autopilot v1.27.8-r0, v1.28.6-r0, and later versions, container subnets can be deleted.

Deleting a cluster container subnet is a high-risk operation. Ensure that the network interfaces used by the cluster are not associated with the subnet.

Procedure

  1. Log in to the CCE console and click the cluster name in the cluster list.
  2. In the navigation pane, choose Settings. Then click the Network tab.
  3. In the Container Network area, copy the network ID of the subnet. (The default-network subnet is used as an example.)

  4. Log in to the Network Console. In the navigation pane, choose Virtual Private Cloud > Subnets. Search for the container subnet using the network ID.
  5. Click the subnet name to go to the Summary tab. In the Resources area, click the number on the Network Interfaces tab and view the network interfaces and supplementary network interfaces associated with the subnet.

  6. View the network interface name or description. If the name or description contains the cluster ID, the network interface is used by the cluster. You can view the cluster ID on the Overview page of the cluster on the CCE console.

    To clear the network interfaces used by the cluster, submit a service ticket.
