Create a RAM role for a trusted Alibaba Cloud account - Resource Access Management

A Resource Access Management (RAM) role whose trusted entity is an Alibaba Cloud account is used to implement cross-account access and temporary authorization. The RAM role can be assumed by a RAM user or a RAM role that belongs to a trusted Alibaba Cloud account.

Procedure

Log on to the RAM console as a RAM user who has administrative rights.
In the left-side navigation pane, choose Identities > Roles.
On the Roles page, click Create Role.
On the Create Role page, set the Principal Type parameter to Cloud Account, specify an Alibaba Cloud account, and then click OK.
- Current Account: If you want a RAM user or RAM role that belongs to your Alibaba Cloud account to assume the RAM role, select Current Account.
- Other Account: If you want a RAM user or RAM role that belongs to a different Alibaba Cloud account to assume the RAM role, select Other Account and enter the ID of the Alibaba Cloud account. This option is provided to grant permissions on resources that belong to different Alibaba Cloud accounts. For more information, see Use a RAM role to grant permissions across Alibaba Cloud accounts. You can view the ID of your Alibaba Cloud account on the Security Settings page.
Optional. If you want the RAM role to be assumed only by a specific RAM user or RAM role that belongs to the trusted Alibaba Cloud account, click Switch to Policy Editor and modify the trust policy of the RAM role in the editor.
The editor supports the Visual editor and JSON modes. In the following example, only the RAM user Alice within the Alibaba Cloud account whose ID is 100******0719 can assume the RAM role.
- Visual editor
  Specify a RAM user for the Principal element.
- JSON
  Specify a RAM user for the RAM field of the Principal parameter.
