    ApsaraDB RDS:Use RAM policies to manage the permissions of RAM users on ApsaraDB RDS instances

    Last Updated:Dec 12, 2024

    This topic describes how to attach Resource Access Management (RAM) policies to RAM users to manage the permissions of the RAM users on ApsaraDB RDS instances.

    Introduction

    Alibaba Cloud allows you to use RAM policies to improve the security of RDS instances. You can use RAM policies to grant different permissions to RAM users on RDS instances. For more information, see RAM policies for ApsaraDB RDS.

    Note

    For more information about RAM policies, see Policy overview.

    Procedure

    1. Log on to the RAM console.

    2. In the left-side navigation pane, choose Permissions > Policies.

    3. On the Policies page, click Create Policy.

    4. On the JSON tab of the page that appears, enter the policy document and click OK.

      Note

    5. In the Create Policy dialog box, configure the Name and Description parameters. Then, confirm the information and click OK.

      Note

      You can also customize the name of the RAM policy. The name of the RAM policy must meet the following requirements:

      • The name must be 1 to 128 characters in length.

      • The name can contain letters, digits, and hyphens (-).

    6. In the left-side navigation pane, choose Permissions > Grants. On the page that appears, click Grant Permission to grant permissions to the required RAM user.

      1. Configure the Resource Scope parameter.

        • Account: The permissions take effect on all resources within the current Alibaba Cloud account.

        • ResourceGroup: The permissions take effect on resources in a resource group.

          Note

          If you want to select the Specific Resource Group option, make sure that ApsaraDB RDS supports resource groups. For more information, see Services that work with Resource Group.

      2. Configure the Principal parameter.

        Note

        The Principal parameter specifies the RAM user to which you want to attach the RAM policy. You can enter a part of the username to perform a fuzzy match to search for the RAM user.

      3. In the Policy section, select Custom Policy from the drop-down list.

      4. Select the RAM policy that you created in Step 4. Then, click OK.

        Note

        You can enter a part of the name of the RAM policy in the search box above the listed RAM policies to perform a fuzzy match to search for the RAM policy.
