Deletes a single security group. When a security group is deleted, the rules in the security group are also deleted.
Operation description
Take note of the following items:
- Before you delete a security group, make sure that the security group does not contain Elastic Compute Service (ECS) instances or elastic network interfaces (ENIs) (because operations of releasing ECS instances and ENIs are asynchronous) and the security group is not referenced by other security groups. Otherwise, the DeleteSecurityGroup request fails. You can call the DescribeSecurityGroupReferences operation to query the reference details of the security group.
- If the
InvalidOperation.DeletionProtectionerror code is returned when you call the DeleteSecurityGroup operation to delete a security group or if a deletion protection-related message appears when you delete a security group in the ECS console, the deletion protection feature is enabled for the security group. When you create a Container Service for Kubernetes (ACK) cluster, the deletion protection feature is enabled for an associated security group to prevent accidental deletion. You cannot manually disable the deletion protection feature for the security group. The deletion protection feature can be automatically disabled only after the ACK cluster is deleted. For more information, see Disable deletion protection for a security group.
