Written by
Updated at October 28, 2024

You can add and delete users as well as manage their individual settings and database access permissions.

Getting a list of users

  1. Go to the folder page and select Managed Service for MongoDB.
  2. Click the name of the cluster you need and select the  Users tab.

If you do not 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.

To get a list of cluster users, run the following command:

yc managed-mongodb user list \
  --cluster-name <cluster_name>

You can request the cluster name with a list of clusters in the folder.

To get a list of users, use the list REST API method for the User resource or the UserService/List gRPC API call and provide the cluster ID in the clusterId request parameter.

You can get the cluster ID with a list of clusters in the folder.

Creating a user

  1. Go to the folder page and select Managed Service for MongoDB.

  2. Click the name of the cluster you need and select the  Users tab.

  3. Click Create user.

  4. Enter the DB user name and password.

    Note

    The username may contain Latin letters, numbers, hyphens, and underscores but must begin with a letter, number, or underscore.

    The password must be between 8 and 128 characters.

  5. Configure the roles for the user:

    1. Click Add database and select the database where you want to grant a role.
    2. Add roles using .

    You can grant multiple roles to a user in different databases.

  6. Click Create.

If you do not 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.

To create a user in a cluster:

  1. See the description of the create user CLI command:

    yc managed-mongodb user create --help

  2. Specify the user properties in the create command:

    yc managed-mongodb user create <username> \
  --cluster-name <cluster_name> \
  --password <user_password> \
  --permission database=<DB_name>,role=<role>,role=<other_role>,... \
  --permission database=<other_DB_name>,role=<role>,...

    Note

    The username may contain Latin letters, numbers, hyphens, and underscores but must begin with a letter, number, or underscore.

    The password must be between 8 and 128 characters.

    You can request the cluster name with a list of clusters in the folder.

  1. Open the current Terraform configuration file with an infrastructure plan.

    For more information about creating this file, see Creating clusters.

  2. Add the yandex_mdb_mongodb_user resource:

    resource "yandex_mdb_mongodb_user" "<username>" {
  cluster_id = <cluster_ID>
  name       = "<username>"
  password   = "<password>"
  permission {
    database_name = "<DB_name>"
    roles         = [ "<list_of_user_roles>" ]
  }
}

    Where database_name is the name of the DB you want to grant access to.

    Note

    The username may contain Latin letters, numbers, hyphens, and underscores but must begin with a letter, number, or underscore.

    The password must be between 8 and 128 characters.

  3. Make sure the settings are correct.

    1. Using the command line, navigate to the folder that contains the up-to-date Terraform configuration files with an infrastructure plan.

    2. Run the command:

      terraform validate

      If there are errors in the configuration files, Terraform will point to them.

  4. Confirm updating the resources.

    1. Run the command to view planned changes:

      terraform plan

      If the resource configuration descriptions are correct, the terminal will display a list of the resources to modify and their parameters. This is a test step. No resources are updated.

    2. If you are happy with the planned changes, apply them:

      1. Run the command:

        terraform apply

      2. Confirm the update of resources.

      3. Wait for the operation to complete.

For more information, see the Terraform provider documentation.

To create a user, use the create REST API method for the User resource or the UserService/Create gRPC API call and provide the following in the request:

  • Cluster ID in the clusterId parameter. To find out the cluster ID, get a list of clusters in the folder.
  • User settings in the userSpec parameter:
    • Username in the name parameter.
    • User password in the password parameter.
    • Database access permissions (one or more permissions parameters, one for each database):

Changing users

  1. Go to the folder page and select Managed Service for MongoDB.

  2. Click the name of the cluster you need and select the  Users tab.

  3. To edit a user password, click in the row with the user you need and select Change password.

If you do not 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.

To change a user's password or list of roles:

  1. See the description of the CLI's update user command:

    yc managed-mongodb user update --help

  2. Specify the user properties in the update command:

    yc managed-mongodb user update <username> \
  --cluster-name <cluster_name> \
  --password <user_password> \
  --permission database=<DB_name>,role=<role>,role=<other_role>,... \
  --permission database=<other_DB_name>,role=<role>,...

    Note

    The password must be between 8 and 128 characters.

To grant a user access to a database with a defined list of roles:

  1. View a description of the CLI command to grant users permissions:

    yc managed-mongodb user grant-permission --help

  2. Specify the properties of the user in the grant permissions command:

    yc managed-mongodb user grant-permission <username> \
  --cluster-name <cluster_name> \
  --database <DB_name> \
  --role <list_of_roles_separated_by_commas>

To revoke user database access:

  1. View a description of the CLI command to revoke users' permissions:
