    Realtime Compute for Apache Flink:Grant permissions to a RAM user

    Last Updated:Dec 06, 2024

    When you access the Realtime Compute for Apache Flink console as a Resource Access Management (RAM) user or by using a RAM role and perform operations such as purchasing, viewing, or deleting a workspace, the RAM user or RAM role must have the required permissions. This topic describes the RAM policy types that are supported by Realtime Compute for Apache Flink and how to grant permissions to a RAM user.

    Policy types

    A policy defines a set of permissions that are described based on the policy structure and syntax. You can use policies to describe the authorized resource sets, authorized operation sets, and authorization conditions. For more information about the policy elements, structure, and syntax, see Policy elements and Policy structure and syntax.

    RAM supports the following two types of policy:

    • System policy: System policies are created and updated by Alibaba Cloud. You can use system policies, but you cannot modify the policies. For more information about the system policies that are supported by Realtime Compute for Apache Flink, see the System policies section of this topic.

    • Custom policy: You can create, update, and delete custom policies to meet your business requirements. For more information about the custom policies that are supported by Realtime Compute for Apache Flink, see the Custom policies section of this topic.

    Procedure

    You can attach a policy to a RAM user or RAM role to grant the RAM user or RAM role the access permissions in the policy. This section describes how to grant permissions to a RAM user. The operations for granting permissions to a RAM role are similar to the operations for granting permissions to a RAM user. For more information, see Grant permissions to a RAM role.

    1. Log on to the RAM console as a RAM administrator.

    2. In the left-side navigation pane, choose Identities > Users.

    3. On the Users page, find the required RAM user, and click Add Permissions in the Actions column.

      image

      You can also select multiple RAM users and click Add Permissions in the lower part of the page to grant permissions to the RAM users at a time.

    4. In the Grant Permission panel, grant permissions to the RAM user.

      Parameter

      Description

      Resource Scope

      The scope of resources that you can access with the granted permissions. Valid values:

      • Account: The permissions are granted to the current Alibaba Cloud account.

      • ResourceGroup: The permissions are valid for a specific resource group.

      Principal

      The principal is the RAM user to which you want to grant permissions. By default, the current RAM user is specified as the principal. You can also specify another RAM user.

      Policy

      • System policy: For more information about the system policies that are supported by Realtime Compute for Apache Flink, see the System policies section of this topic.

      • Custom policy: For more information about how to create a custom policy, see Create custom policies. For more information about the custom policies that are supported by Realtime Compute for Apache Flink, see the Custom policies section of this topic. The following sample code provides the document of a policy that allows a RAM user to view the information about all workspaces.

            "Effect": "Allow"
        }
    ]
}

    Policies related to Realtime Compute for Apache Flink

    Note

    In a policy, Action indicates the operation that needs to be performed, Resource indicates the object on which the operation is performed, and Effect specifies whether to allow or deny the operation on the object. For more information about the syntax and structure of RAM policies, see Policy structure and syntax. You must replace the following parameters in a policy with the actual values:

    • {#regionId}: the ID of the region in which the Realtime Compute for Apache Flink workspace that you want to manage resides.

    • {#accountId}: the ID of the Alibaba Cloud account.
