Access management in Managed Service for YDB

Yandex Cloud users can only perform operations on resources that are allowed by the roles assigned to them. As long as a user has no roles assigned, almost all operations are forbidden.

To enable access to YDB resources (databases and their users), assign the required roles from the list below to a Yandex account, service account, federated users, user group, system group, or public group. A role can be assigned for a parent resource (folder or cloud) whose roles are inherited by nested resources.

You can also grant a role to access a specific database. This will allow a user without any roles in the directory hosting the database to access the database according to the role assigned.

Roles for a resource can be assigned by users who have the ydb.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
