How Can I Delete a Security Group Rule Associated with a Deleted Subnet?
Scenarios
Pod subnets can be deleted from CCE Turbo clusters of 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
- Log in to the CCE console and click the cluster name to access the cluster console.
- In the navigation pane, choose Settings and click the Network tab.
- In the Container Network area, copy the IPv4 CIDR block of the subnet. (The default-network is used as an example.)
- In the navigation pane, choose Overview. In the Networking Configuration area, click the name of the default node security group.
- On the page displayed, click the Inbound Rules tab, locate the row containing the subnet CIDR block based on the source IP address, and find the corresponding security group rule.
- Click Delete in the Operation column.
