Access management in Compute Cloud

In this section, you will learn:

• Which resources you can assign a role for.
• Which roles exist in the service.

About access managementAbout access management

In Yandex Cloud, all transactions are checked in Yandex Identity and Access Management. If a subject does not have the required permission, the service returns an error.

To grant permissions for a resource, assign roles for this resource to the subject that will perform the operations. You can assign roles to a Yandex account, service account, federated users, user group, system group, or public group. For more information, see How access management works in Yandex Cloud.

Roles for a resource can be assigned by users who have the compute.admin role or one of the following roles for that resource:

• admin
• resource-manager.admin
• organization-manager.admin
• resource-manager.clouds.owner
• organization-manager.organizations.owner

Which resources you can assign a role forWhich resources you can assign a role for

You can assign a role to an organization, cloud, or folder. The roles assigned for organizations, clouds, or folders also apply to nested resources.

In the management console, you can assign a role through the YC CLI or the Yandex Cloud API for individual resources of the service:

• VM instance
• Instance group
• Dedicated host group
• VM placement group
• Non-replicated disk placement group
• VM disk
• GPU cluster
• Image
• Snapshot schedule
• Disk snapshot
• File storage

Which roles exist in the serviceWhich roles exist in the service

The chart below shows which roles are available in the service and how they inherit each other's permissions. For example, the editor role includes all the permissions of viewer. You can find the description of each role under the chart.

For more information about service roles, see Roles in the Yandex Identity and Access Management service documentation.

Primitive rolesPrimitive roles

Primitive roles allow users to perform actions in all Yandex Cloud services.

auditorauditor

The auditor role grants a permission to read configuration and metadata of any Yandex Cloud resources without any access to data.

For instance, users with this role can:

• View info on a resource.
• View the resource metadata.
• View the list of operations with a resource.

auditor is the most secure role that does not grant any access to the service data. This role suits the users who need minimum access to the Yandex Cloud resources.

viewerviewer

The viewer role grants the permissions to read the info on any Yandex Cloud resources.

This role also includes the auditor permissions.

Unlike auditor, the viewer role provides access to service data in read mode.

editoreditor

The editor role provides permissions to manage any Yandex Cloud resources, except for assigning roles to other users, transferring organization ownership, removing an organization, and deleting Key Management Service encryption keys.

For instance, users with this role can create, modify, and delete resources.

This role also includes the viewer permissions.

adminadmin

The admin role enables assigning any roles, except for resource-manager.clouds.owner and organization-manager.organizations.owner, and provides permissions to manage any Yandex Cloud resources (except for transferring organization ownership and removing an organization).

Prior to assigning the admin role for an organization, cloud, or billing account, make sure to check out the information on protecting privileged accounts.

This role also includes the editor permissions.

Instead of primitive roles, we recommend using service roles. This ensures more selective access control and implementation of the principle of least privilege.

For more information about primitive roles, see the Yandex Cloud role reference.
