How Do I Know the Instances Associated with a Security Group?
When you create an instance, such as ECS, cloud container, or database, you need to add the instance to a security group. To delete a security group, you must remove all instances from the security group first.
You can perform the following operations to view the instances associated with a security group:
- In the security group list, locate the row that contains the target security group and click Manage Instance in the Operation column.
On the Associated Instances tab, you can view instances associated with the security group, such as servers and extension NICs.
If there is no instance associated with the security group on the Associated Instances tab, but the system still displays a message indicating that the security group has instances associated, perform the following operations:
- In the upper right corner of the console, choose Resources > My Resources and check whether there are resources listed in Table 1 in the same region as the security group.
