Access management in Managed Service for Greenplum®

In this section, you will learn:

• Which resources you can assign a role for.
• Which roles exist in the service.
• Which roles are required for particular actions.

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 mdb.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.

To allow access to service resources (DB clusters and hosts, cluster backups, databases and their users), assign the user the appropriate roles for the folder, cloud, or organization containing these resources.

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.

To create Greenplum® clusters, you also need the vpc.user role.

mdb.auditormdb.auditor

The mdb.auditor role grants the minimum permissions required to view information about managed database clusters (without access to data or runtime logs).

Users with this role can view information about managed database clusters, quotas, and folders.

This role also includes the managed-opensearch.auditor, managed-kafka.auditor, managed-mysql.auditor, managed-sqlserver.auditor, managed-postgresql.auditor, managed-greenplum.auditor, managed-clickhouse.auditor, managed-redis.auditor, and managed-mongodb.auditor permissions.

mdb.viewermdb.viewer

The mdb.viewer role grants read access to managed database clusters and cluster runtime logs.

Users with this role can read from databases, inspect the logs of managed database clusters, and view information about clusters, quotas, and folders.

This role also includes the mdb.auditor, managed-opensearch.viewer, managed-kafka.viewer, managed-mysql.viewer, managed-sqlserver.viewer, managed-postgresql.viewer, managed-greenplum.viewer, managed-clickhouse.viewer, managed-redis.viewer, managed-mongodb.viewer, and dataproc.viewer permissions.

mdb.adminmdb.admin

The mdb.admin role grants full access to managed database clusters.

Users with this role can create, edit, delete, run, and stop managed database clusters, manage cluster access, read and write to databases, and view information about clusters, runtime logs, quotas, and folders.

This role also includes the mdb.viewer, vpc.user, managed-opensearch.admin, managed-kafka.admin, managed-mysql.admin, managed-sqlserver.admin, managed-postgresql.admin, managed-greenplum.admin, managed-clickhouse.admin, managed-redis.admin, managed-mongodb.admin, and dataproc.admin permissions.

When you create a Managed Service for Greenplum® cluster, an admin user with the mdb_admin role is created automatically. This role replaces the superuser when working with the database and is not similar to the mdb.admin role in Yandex Cloud. For more information, see Users and roles in Managed Service for Greenplum®.

vpc.publicAdminvpc.publicAdmin

The vpc.publicAdmin role allows you to manage NAT gateways, public IP addresses, and external network connectivity, as well as view information on the quotas, resources, and resource operations. This role grants administrator privileges for multi-interface instances that provide connectivity between multiple networks.

Users with this role can:

• View the list of cloud networks and info on them, as well as set up external access to them.
• Manage connectivity of multiple cloud networks.
• Manage multi-interface instances that provide connectivity between multiple networks.
• View the list of subnets and info on them, as well as modify them.
• View information on NAT gateways, as well as create, modify, and delete them.
• Connect NAT gateways to route tables.
• View the list of cloud resource addresses and info on them, as well as create, update, and delete public IP addresses.
• View the list of route tables and info on them, as well as link them to subnets.
• View the list of security groups and the info on them.
• View information on the IP addresses used in subnets.

• View info on the relevant folder.

This role also includes the vpc.viewer permissions.

You can assign a role for a cloud or folder.

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.

Roles requiredRoles required

To use the service, you need the managed-greenplum.editor role or higher for the folder to house the new cluster. The managed-greenplum.viewer role enables you only to view the list of clusters.

To create a Managed Service for Greenplum® cluster, you need the vpc.user role and the managed-greenplum.editor role or higher.

You can always assign a role with more permissions. For instance, you can assign managed-greenplum.admin instead of managed-greenplum.editor.
