- Go to the Custom tab.
- Choose a platform.
- Specify the guaranteed share and required number of vCPUs, as well as RAM size.
- Enable a software-accelerated network if needed.
- If required, make your VM preemptible.
Note
Each public image has its own minimum requirements for a VM. A GitLab image from Yandex Cloud Marketplace, for instance, requires at least 4 virtual cores and 8 GB of RAM.
-
Under Network settings:
-
In the Subnet field, enter the ID of a subnet in the new VM’s availability zone. Alternatively, you can select a cloud network from the list.
-
Each network must have at least one subnet. If there is no subnet, create one by selecting Create subnet.
-
If you do not have a network, click Create network to create one:
- In the window that opens, enter the network name and select the folder to host the network.
- (Optional) Select the Create subnets option to automatically create subnets in all availability zones.
- Click Create network.
-
-
In the Public IP field, choose a method for assigning an IP address:
Auto
: Assign a random IP address from the Yandex Cloud IP address pool. In this case, 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 Converting a dynamic public IP address to static.No address
: Do not 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.List
: Select a private IP address from the list of previously reserved IP addresses. Click Reserve to reserve a private IP address in the selected subnet if needed.- 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
Detect automatically
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 via 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 the VM, 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](../../../compute/operations/vm-connect/ssh.md#creating-ssh-keys) 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.
Note
On VMs with access via OS Login enabled, provide your custom SSH keys through metadata.
-
-
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 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.
