Create a VM with disks restored from snapshots
You can create a VM with disks restored from the snapshots that exist in the folder. For information on creating a disk snapshot, please see Creating a disk snapshot.
To create a VM:
-
In the management console, select the folder to create the virtual machine in.
-
In the list of services, select Compute Cloud.
-
Click Create VM.
-
Under Basic parameters:
-
Enter a name and description for the VM. Naming requirements:
- The length can be from 3 to 63 characters.
- It may contain lowercase Latin letters, numbers, and hyphens.
- The first character must be a letter. The last character can't 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.
-
Select an availability zone to put your virtual machine in.
-
-
Under Image/boot disk selection, select one of the images.
-
Under Disks and file storage, add a disk:
- Click Add disk.
- Enter the disk name.
- Select the disk type.
- Specify the desired block size.
- Specify the necessary disk size.
- (optional) Enable the Delete with the VM option if you need to automatically delete the disk when deleting the VM it will be attached to.
- Select
Snapshot
as content. - Select the snapshot from the list.
- Click Add.
- (optional) Under Disks and file storage, click the File storage tab and connect a file store:
- Click Connect file storage.
- In the resulting window, select a file store.
- Enter a device name.
- Click Connect file storage.
-
Under Computing resources:
- Choose a platform.
- Specify the guaranteed share and the required number of vCPUs, as well as the amount of RAM.
- If necessary, make your VM preemptible.
- (optional) Enable a software-accelerated network.
-
Under Network settings:
-
Enter a subnet ID or select a cloud network from the list.
If you don't have a network, click Create network to create one:- In the window that opens, enter the network name and folder to host the network.
- (optional) To automatically create subnets, select the Create subnets option.
- Click Create.
Each network must have at least one subnet. If there is no subnet, create one by selecting Add subnet.
-
In the Public IP field, choose a method for assigning an IP address:
- Auto: Assign a random IP address from the Yandex Cloud IP pool. With this, you can enable DDoS protection using the option below.
- List: Select a public IP address from the list of previously reserved static addresses. For more information, see Making a dynamic public IP address static.
- No address: Don't assign a public IP address.
-
In the Internal address field, select the method for assigning internal addresses: Auto or Manual.
-
(optional) Create records for the VM in the DNS zone:
- Expand DNS settings for internal addresses and click Add record.
- Specify the zone, FQDN, and TTL for the record. When setting the FQDN, you can select Detect automatically for the zone.
You can add multiple records to internal DNS zones. For more information, see Cloud DNS integration with Compute Cloud.
-
Select appropriate security groups (if there is no corresponding field, the virtual machine will be enabled for all incoming and outgoing traffic).
-
(optional) To automatically back up your instances using Cloud Backup, under Backup, select the option of connecting an instance to the service.
The option shows up if you requested access to the service from our technical support and selected a supported operating system for your VM. For more information about setting up a VM, see Connecting Compute Cloud instances to Cloud Backup.
-
-
Under Access, specify the data required to access the VM:
-
(optional) Select or create a service account. By using a service account, you can flexibly configure access rights for your resources.
-
Enter the username in the Login field.
Alert
Don't use the username
root
or other names reserved by the operating system. To perform operations that require superuser permissions, use the commandsudo
. -
In the SSH key field, paste the contents of the public key file.
-
If required, grant access to the serial console.
-
-
Click Create VM.
The virtual machine appears in the list. When a VM is created, it is assigned an IP address and hostname (FQDN).
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.
-
View the description of the CLI command for creating a VM:
yc compute instance create --help
-
Prepare snapshots of the required disks, see Creating a disk snapshot.
-
Get a list of snapshots in the default folder:
yc compute snapshot list +----------------------+-----------------+----------------------+--------+----------------------------+ | ID | NAME | PRODUCT IDS | STATUS | DESCRIPTION | +----------------------+-----------------+----------------------+--------+----------------------------+ | fd8rlt1u2rf0lps3rqm9 | first-snapshot | f2ecl5vhsftdean0sr6s | READY | my first snapshot via CLI | | fhmolt1u2rf0lps3lsaf | second-snapshot | f2eclmol5lps3rqmfl5f | READY | my second snapshot via CLI | +----------------------+-----------------+----------------------+--------+----------------------------+
-
Select the identifier (
ID
) or name (NAME
) of the necessary snapshots. -
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 the 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, remove the
--public-ip
flag.
Use the create method for the Instance
resource.
