Removing an instance from a placement group

If you don't have the Yandex.Cloud command line interface yet, install and initialize it.

The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name or --folder-id parameter.

1. View a list of VM instances in the placement group:

   $ yc compute placement-group list-instances --name my-group
   +----------------------+---------------------+---------------+---------+-------------+-------------+
   |          ID          |        NAME         |    ZONE ID    | STATUS  | EXTERNAL IP | INTERNAL IP |
   +----------------------+---------------------+---------------+---------+-------------+-------------+
   | epdep2kq6dt5uekuhcrd | instance-in-group-1 | ru-central1-b | RUNNING |             | 10.129.0.5  |
   | epdlv1pp54019j09fhue | instance-in-group-2 | ru-central1-b | RUNNING |             | 10.129.0.30 |
   +----------------------+---------------------+---------------+---------+-------------+-------------+
   

2. Stop the VM instance that you want to remove:

   $ yc compute instance stop instance-in-group-2
   id: epdlv1pp54019j09fhue
   ...
   status: STOPPED
   

3. Remove the VM instance from the placement group. To do this, update the VM instance, leaving the placement group name (placement-group-name) blank:

   $ yc compute instance update --name instance-in-group-2 --placement-group-name=""
   

4. Check that the VM instance was removed from the group:

   $ yc compute placement-group list-instances --name my-group
   +----------------------+---------------------+---------------+---------+-------------+-------------+
   |          ID          |        NAME         |    ZONE ID    | STATUS  | EXTERNAL IP | INTERNAL IP |
   +----------------------+---------------------+---------------+---------+-------------+-------------+
   | epdep2kq6dt5uekuhcrd | instance-in-group-1 | ru-central1-b | RUNNING |             | 10.129.0.5  |
   +----------------------+---------------------+---------------+---------+-------------+-------------+
