Create a VM with disks restored from snapshots
You can create a VM with disks restored from the snapshots that exist in the folder. Read about creating a disk snapshot in Creating a disk snapshot.
Note
Disks, snapshots, and images are separate resources that work independently from each other in Compute Cloud. You can create, delete, and manage them separately. Your actions with a disk do not affect that disk's snapshot or the image the disk was created out of. Even if you delete the disk or the VM with the disk, its snapshot and image will remain intact.

: Select a public IP address from the list of previously reserved static addresses. For more information, see Converting a dynamic public IP address to static.No address
: Not to assign a public IP address.
-
Select the appropriate security groups. If you leave this field empty, the default security group will be assigned to the VM.
-
Expand the Additional section and select a method for internal IP address assignment in the Internal IPv4 address field:
Auto
: Assign a random IP address from the pool of IP addresses available in the selected subnet.Manual
: Manually assign a private IP address to the VM.- Enable the DDoS protection option, if needed. The option is available if you previously selected the automatic IP assignment method in the public address settings.
-
(Optional) Create records for the VM in the DNS zone:
- Expand the DNS settings for internal addresses section and click Add record.
- Specify the zone, FQDN, and TTL for the record. When setting the FQDN, you can select

for the zone.
You can add multiple records to internal DNS zones. For more information, see Cloud DNS integration with Compute Cloud. - To create another record, click Add record.
If you want to attach an additional network interface to your VM, click Add network interface and repeat the settings from this step for the new interface. You can add up to eight network interfaces to a single VM.
-
-
Under Access:
-
Select Access by OS Login to connect and manage access to the new VM using OS Login in Yandex Cloud Organization.
With OS Login, you can connect to VMs using SSH keys and SSH certificates via a standard SSH client or the Yandex Cloud CLI. OS Login allows you to rotate the SSH keys used to access VMs, providing the most secure access option.
-
If you prefer not to use OS Login, select SSH key and specify the following info for VM access:
-
Under Login, enter the username.
Alert
Do not use
root
or other usernames reserved by the OS. To perform operations requiring superuser permissions, use thesudo
command. -
In the SSH key field, select the SSH key saved in your organization user profile.
If there are no saved SSH keys in your profile, or you want to add a new key:
- Click Add key.
- Enter a name for the SSH key.
- Upload or paste the contents of the public key file. You need to create a key pair for the SSH connection to a VM yourself.
- Click Add.
The SSH key will be added to your organization user profile.
If users cannot add SSH keys to their profiles in the organization, the added public SSH key will only be saved to the user profile of the VM being created.
-
If you want to add several users with SSH keys to the VM at the same time, specify these users' data under Metadata. You can also use metadata to install additional software on a VM when creating it.
In public Linux images provided by Yandex Cloud, the functionality of connecting over SSH using login and password is disabled by default.
-
-
Under General information, specify the VM name:
- The name must be from 3 to 63 characters long.
- It may contain lowercase Latin letters, numbers, and hyphens.
- The first character must be a letter and the last character cannot be a hyphen.
Note
The VM name is used to generate an internal FQDN only once: when creating a VM. If the internal FQDN is important to you, choose an appropriate name for the VM at the creation stage.
-
Under Additional:
-
(Optional) Select or create a service account. With a service account, you can flexibly configure access rights for your resources.
-
(Optional) Grant access to the serial console.
-
(Optional) Under Backup, enable Connect and select or create a backup policy to back up your VMs automatically using Cloud Backup.
For more information, see Connecting Compute Cloud VMs and Yandex BareMetal servers to Cloud Backup.
-
(Optional) Under Monitoring, enable the Agent for delivering metrics option to configuire delivery of metrics to Yandex Monitoring.
-
(Optional) Under Placement, select a VM placement group.
-
-
Click Create VM.
You will see the new VM in the list. Every new VM gets an IP address and host name (FQDN).
If you do not 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.
-
View the description of the CLI command for creating a VM:
yc compute instance create --help
-
Prepare the snapshots of the disks, see Creating a disk snapshot.
-
Get a list of snapshots in the default folder:
yc compute snapshot list
Result:
+----------------------+-----------------+----------------------+--------+----------------------------+ | ID | NAME | PRODUCT IDS | STATUS | DESCRIPTION | +----------------------+-----------------+----------------------+--------+----------------------------+ | fd8rlt1u2rf0l******* | first-snapshot | f2ecl5vhsftd******** | READY | my first snapshot via CLI | | fhmolt1u2rf0******** | second-snapshot | f2eclmol5lps******** | READY | my second snapshot via CLI | +----------------------+-----------------+----------------------+--------+----------------------------+
-
Select the IDs (
ID
) or names (NAME
) of the snapshots you need. -
Create a VM in the default folder:
yc compute instance create \ --name first-instance \ --zone ru-central1-a \ --public-ip \ --create-boot-disk snapshot-name=first-snapshot \ --create-disk snapshot-name=second-snapshot \ --ssh-key ~/.ssh/id_ed25519.pub
This command creates a VM named
first-instance
in theru-central1-a
availability zone, with a public IP and disks from the snapshots.Note
The VM name is used to generate an internal FQDN only once: when creating a VM. If the internal FQDN is important to you, choose an appropriate name for the VM at the creation stage.
To create a VM without a public IP address, remove the
--public-ip
flag.If you want to add multiple network interfaces to the VM, specify the
--network-interface
parameter as many times as you need. You can add up to eight network interfaces to a single VM.
Use the create REST API method for the Instance resource or the InstanceService/Create gRPC API call.
