Last update: October 05 2026Open in Markdown

Before deleting a group, you must detach it from all ports it is assigned to.

Control panel

1. Make sure you have detached the security group from all ports. You can view the list of ports with the group in the control panel: in the top menu, click Products → Cloud Servers → Security groups → security group page → Ports tab.

2. In the control panel, in the top menu, click Products and select Cloud Servers.

3. Go to the Security groups section.

4. In the security group's menu, select Delete.

5. Click Delete.

OpenStack CLI

1. Open the OpenStack CLI.

2. Detach the group from each individual port in the public or private subnet it is assigned to:

   openstack port unset \
       --security-group <security-group> \
       <port>

   Specify:

   • <security_group> — security group ID or name, which can be viewed using the command openstack security group list;
   • <port> — ID of the port with the group, which can be copied in the control panel: in the top menu, click Products → Cloud Servers → Security groups → security group page → Ports tab → in the UUID field, click .

3. If the group is assigned to a port with a direct public IP address, detach it from the port using the Control Panel.

4. Delete the security group:

   openstack security group delete <security_group>

   Specify <security_group> — security group ID, which can be viewed using the command openstack security group list.
