Managing access to DataLens

Access to Yandex DataLens is managed from the Yandex.Cloud console.
To grant a user access, assign them a DataLens role.

Permission differentiation in the service is implemented at the object and directory level.
You can grant users permission to each object and directory. They determine which operations are allowed. If you created or copied a directory or object, they will have the same permissions as their new parent folder.

You can grant users access to a directory or any service object:

• Connection
• Datasets
• Charts
• Dashboards

Users can also request permission on their own via the request form. For more information, see Request permissions.

User roles

Roles enable you define user permissions in a DataLens instance:

• datalens.instances.user: A DataLens user with the permissions to create, read, and update objects based on object permissions.
• datalens.instances.admin: A DataLens instance administrator. The role is automatically assigned to the instance creator. The administrator has the datalens.instances.user rights and can also change the service plan and pay for the paid content in Cloud Marketplace.

User roles are assigned in the Yandex.Cloud console.

Adding a user

You can add users with a Yandex account and federated users.

Add a user with a Yandex account

To add a user and grant them access to DataLens:

1. Open the Access management page for the selected cloud. If necessary, switch to another cloud.

2. On the Users and roles page, click Add user in the upper-right corner.

3. Enter the user's Yandex email address.

4. Click Add. When a new user is added to the cloud, they're automatically assigned the cloud member role: resource-manager.clouds.member.

   Note

   It may take several hours before the username of the added user appears in the form for granting permissions.

5. Select the user to assign the role to, click , and choose Configure roles.

6. To add a role for a cloud, click in the Roles for the cloud section.

   To add a role for a folder, select the folder and click Assign role in the Roles for folders section.

7. Choose datalens.instances.user or datalens.instances.admin from the list.

Add federated users

To add federated users, you need to know the users' Name IDs returned by the Identity Provider (IdP) server with the successful authentication response. This is usually the user's primary email address. If you don't know what the server returns as the Name ID, contact the administrator who configured authentication for your federation.

1. Add federated users:

   Management console

   CLI

   API

   To add identity federation users to the cloud:

   1. Open the Access management page for the selected cloud. If necessary, switch to another cloud.

   2. Click the arrow next to the Add user button.
   3. Select Add federated users.
   4. Select the identity federation to add users from.
   5. List the Name IDs of users, separating them with line breaks.

   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.

   1. View a description of the add user command:

      $ yc iam federation add-user-accounts --help
      

   2. Add users by listing their Name IDs separated by a comma:

      $ yc iam federation add-user-accounts --name my-federation \
        --name-ids=alice@example.com,bob@example.com,charlie@example.com
      

   To add identity federation users to the cloud:

   1. Create a file with the request body (for example, body.json). In the request body, specify the array of Name IDs of users you want to add:

      {
        "nameIds": [
          "alice@example.com",
          "bob@example.com",
          "charlie@example.com"
        ]
      }
      

   2. Send the request by specifying the Federation ID in the parameters:

      $ curl -X POST \
        -H "Content-Type: application/json" \
        -H "Authorization: Bearer <IAM token>" \
        -d '@body.json' \
        https://iam.api.cloud.yandex.net/iam/v1/saml/federations/<federation ID>:addUserAccounts
      

2. Select the user to assign the role to, click , and choose Configure roles.

3. To add a role for a cloud, click in the Roles for the cloud section.

   To add a role for a folder, select the folder and click Assign role in the Roles for folders section.

4. Choose datalens.instances.user from the list.

For more information about assigning roles in Yandex.Cloud, see Roles.

Object permissions

Permissions can be assigned to individual users or the All group that includes users who passed authentication.
You can assign the following permissions to objects and directories in DataLens:

• Execute
• Read
• Write
• Admin

Execute

A user with the Execute permission for a connection can make requests to it, but can't create datasets. Regardless of dataset permissions, the user can't access a list of tables in a dataset or view the SQL subquery that the dataset is based on.

A user with the Execute permission for a dataset can make requests to it and create charts, but can't view the dataset.

Granting users the Execute permission lets you:

• Reduce the number of requests to the source, thereby reducing the load on the connection source.

• Better control what data can be shown from a dataset. You can hide some source fields so that users can't view all fields.

• Restrict the creation of subqueries to the source database. A user with the Execute permission can't write subqueries.

Read

A user with the Read permission can view dashboards, widgets, datasets, and directories.

Write

A user with the Write permission can edit dashboards, widgets, connections, datasets, and directories.

The Write permission includes everything under the Read permission.

Admin

A user with the Admin permission can edit available objects and directories, as well as edit permissions.

The Admin permission includes everything included in the Write permission.

A DataLens user can get access logs for DataLens objects (view, edit, delete).
To get logs, you can contact the technical support.
