Creating a User Group and Assigning Permissions

As an administrator, you can create user groups, and grant them permissions by attaching policies or roles. Users you add to the user groups inherit permissions of the policies or roles. IAM provides general permissions (such as administrator or read-only permissions) for each cloud service, which you can assign to user groups. Users in the groups can then use cloud services based on the assigned permissions. For details, see Assigning Permissions to an IAM User. For details about the system permissions of all cloud services, see System Permissions.

Prerequisites

Before creating a user group, learn about the following:

Creating a User Group

  1. Log in to the IAM console as an administrator.
  2. On the IAM console, choose User Groups from the navigation pane, and click Create User Group in the upper right corner.

    Figure 1 Creating a user group

  3. On the displayed page, enter a user group name.
  4. Click OK.

    You can create a maximum of 20 user groups. To create more user groups, increase the quota by referring to How Do I Increase My Quota?

Assigning Permissions to a User Group

To assign permissions to a user group, do as follows:

  1. In the user group list, click Authorize in the row that contains the newly created user group.

    Figure 2 Going to the user group authorization page

  2. On the Authorize User Group page, select the permissions to be assigned to the user group and click Next.

    If the system-defined policies do not meet your requirements, click Create Policy in the upper right to create custom policies. You can use them to supplement system-defined policies for refined permissions control. For details, see Creating a Custom Policy.
    Figure 3 Selecting permissions

  3. Specify the scope. The system automatically recommends an authorization scope for the permissions you selected. Table 1 describes all the authorization scopes provided by IAM.

    Table 1 Authorization scopes

    Scope

    Description

    All resources

    IAM users can use the resources in all region-specific projects and the global service project in your account as specified by the permissions.

    Enterprise projects

    IAM users can use the resources in the enterprise projects you select, as specified by the permissions. This option is available only when the enterprise project function has been enabled.

    For details about enterprise projects, see What is Enterprise Project Management Service?. To enable the enterprise project function, see Enabling the Enterprise Project Function.

    Region-specific projects

    IAM users can use the resources in the region-specific projects you select, as specified by the permissions.

    If some of the selected permissions belong to global services, the system automatically sets the authorization scope of these permissions to All resources. Selected permissions for project-level services will apply to the region-specific projects you select.

    Global services

    IAM users can use global services as specified by the permissions. Global services are deployed with no physical regions specified. IAM users do not need to specify a region when accessing these services, such as Object Storage Service (OBS) and Content Delivery Network (CDN).

    If some of the selected permissions belong to project-level services, the system automatically sets the authorization scope of these permissions to All resources. Selected permissions for global services will apply to the global services.

  4. Click OK.

Table 2 lists the common permissions. For the complete list of service-specific permissions, see System Permissions.

  • If you add a user to multiple groups, the user will inherit all the permissions that have been assigned to the groups.
