Deleting a network interface from a VM

If you do not have the Yandex Cloud CLI yet, install and initialize it.

The folder used by default is the one specified when creating the CLI profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also specify a different folder for any command using --folder-name or --folder-id. If you access a resource by its name, the search will be limited to the default folder. If you access a resource by its ID, the search will be global, i.e., through all folders based on access permissions.

1. See the description of the CLI command for deleting a network interface from a VM:

   yc compute instance detach-network-interface --help
   

2. Get a list of VMs in the default folder:

   yc compute instance list
   

   Result:

   +----------------------+-----------------+---------------+---------+----------------------+
   |          ID          |       NAME      |    ZONE ID    | STATUS  |     DESCRIPTION      |
   +----------------------+-----------------+---------------+---------+----------------------+
   | fhm0b28lgfp4******** | first-instance  | ru-central1-a | RUNNING | my first vm via CLI  |
   | fhm9gk85nj7g******** | second-instance | ru-central1-a | RUNNING | my second vm via CLI |
   +----------------------+-----------------+---------------+---------+----------------------+
   

   Save the ID of the VM from which you want to delete a network interface.

3. Stop the selected VM if needed by specifying its ID:

   Note

   The feature of adding and removing network interfaces on running VMs is at the Preview stage. To access the feature, contact support.

   yc compute instance stop <VM_ID>
   

4. Get a list of network interfaces for the selected VM by specifying its ID:

   yc compute instance get <VM_ID>
   

   Result:

   ...
   network_interfaces:
     - index: "0"
       mac_address: d0:0d:1a:**:**:**
       subnet_id: e2lrucutusnd********
       primary_v4_address:
         address: 192.168.1.20
         one_to_one_nat:
           address: 158.***.**.***
           ip_version: IPV4
       security_group_ids:
         - enpuatgvejtn********
     - index: "1"
       mac_address: d0:1d:1a:**:**:**
       subnet_id: e2lpp96bvvgp********
       primary_v4_address:
         address: 192.168.2.3
       security_group_ids:
         - enpuatgvejtn********
         - enpg8d2hqh1o********
     - index: "2"
       mac_address: d0:2d:1a:**:**:**
       subnet_id: e2lv9c6aek1d********
       primary_v4_address:
         address: 192.168.4.17
       security_group_ids:
         - enpuatgvejtn********
         - enpg8d2hqh1o********
   ...
   

   Save the number (the index field value) of the network interface you want to delete.

5. Delete the network interface:

   yc compute instance detach-network-interface \
     --id <VM_ID> \
     --network-interface-index <network_interface_number>
   

   Where:

   • --id: ID of the selected VM. Instead of the ID, you can use the --name parameter to specify the VM name.
   • --network-interface-index: Previously saved number of the VM's network interface you need to delete.

   Result:

   ...
   network_interfaces:
     - index: "0"
       mac_address: d0:0d:1a:**:**:**
