How Can I Delete a Security Group Rule Associated with a Deleted Subnet?

Scenarios

Pod subnets can be deleted from CCE Turbo clusters v1.23.17-r0, v1.25.12-r0, v1.27.9-r0, v1.28.7-r0, v1.29.3-r0, or later versions.

When you delete a subnet, CCE does not automatically remove the security group rules associated with the subnet in the default node security group created by CCE. You must manually delete these rules.

Procedure

  1. Log in to the CCE console and click the cluster name to access the cluster console.
  2. In the navigation pane, choose Settings and click the Network tab.
  3. In the Container Network area, copy the IPv4 CIDR block of the subnet. (The default-network is used as an example.)

  4. In the navigation pane, choose Overview. In the Networking Configuration area, click the name of the default node security group.
  5. On the page displayed, click the Inbound Rules tab, locate the row containing the target subnet CIDR block based on the source IP address, and find the corresponding security group rule.

  6. Click Delete in the Operation column.
