Creating an instance in 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 description of the CLI command to create a placement group:

   $ yc compute placement-group create --help
   

2. Create a placement group:

   $ yc compute placement-group create --spread-strategy --name my-group
   id: fdvte50kv3nclagfknoc
   folder_id: aoeieef3k7ppari05ajo
   created_at: "2019-12-20T08:59:44Z"
   name: my-group
   spread_placement_strategy: {}

   • Named my-group.
   • Placement strategy spread.

3. View the description of the CLI command for creating a VM:

   $ yc compute instance create --help
   

4. Create a virtual machine:

   $ yc compute instance create --zone ru-central1-b --name instance-in-group-1 --placement-group-name my-group
   id: epdep2kq6dt5uekuhcrd
   ...
   placement_policy:
     placement_group_id: fd83bv4rnsna2sjkiq4s
   

   This command creates a VM instance with the following characteristics:

   • Named instance-in-group-1.
   • In the ru-central1-b availability zone.
   • In the my-group placement group.

5. Check that the instance was created and added to the placement group:

   $ yc compute placement-group list-instances --name my-group
