Creating a VM from a set of disks

You can create a VM from existing disks. The disks must reside in one of the availability zones and not be added to other VMs.

When you select a disk to attach to a VM, you can specify whether that disk should be deleted when deleting the VM. You can choose this option when creating a VM, updating it, or attaching a new disk to it.

To create a VM from a set of disks:

CLI

API

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.

See the description of the CLI's create VM command:
```
$ yc compute instance create --help
```

Get a list of disks in the default folder:

yc compute disk list

Result:

+----------------------+--------------+-------------+---------------+--------+----------------------+-------------------------+
|          ID          |     NAME     |    SIZE     |     ZONE      | STATUS |     INSTANCE IDS     |       DESCRIPTION       |
+----------------------+--------------+-------------+---------------+--------+----------------------+-------------------------+

Select the ID or NAME of the necessary disks.
Create a VM in the default folder:
```
$ yc compute instance create \
    --name first-instance \
    --zone ru-central1-a \
    --public-ip \
    --use-boot-disk disk-name=first-disk \
    --attach-disk disk-name=second-disk \
    --ssh-key ~/.ssh/id_rsa.pub
```
This command creates a VM named first-instance in the ru-central1-a availability zone, with a public IP and two disks. To create a VM without a public IP, remove the --public-ip flag.
- Length — from 3 to 63 characters.
- The name may contain lowercase Latin letters, numbers, and hyphens.
- The first character must be a letter. The last character can't be a hyphen.
To specify whether to delete the disk when deleting the VM, set the --auto-delete flag:
```
yc compute instance create \
--name first-instance \
--zone ru-central1-a \
--public-ip \
--use-boot-disk disk-name=first-disk,auto-delete=yes \
--attach-disk disk-name=second-disk,auto-delete=yes \
--ssh-key ~/.ssh/id_rsa.pub
```

Use the Create method for the Instance resource.
