Adding a VM to 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. Create a virtual machine:

   $ yc compute instance create --zone ru-central1-b --name instance-in-group-2
   id: epdlv1pp54019j09fhue
   ...
   

   This command creates a VM instance with the following characteristics:

   • Named instance-in-group-2.
   • In the ru-central1-b availability zone.

2. 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  |
   +----------------------+---------------------+---------------+---------+-------------+-------------+
   

3. Stop the VM:

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

4. Add a VM instance to the placement group:

   $ yc compute instance update --name instance-in-group-2 --placement-group-name my-group
   id: epdlv1pp54019j09fhue
   ...
   placement_policy:
     placement_group_id: fd83bv4rnsna2sjkiq4s
   

   This command adds the instance-in-group-2 instance to the my-group placement group.

5. Check that the instance was added to 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 | STOPPED |             | 10.129.0.30 |
   +----------------------+---------------------+---------------+---------+-------------+-------------+
   

6. Start the VM:

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