    Cloud Phone:Grant a RAM user full access to CADT

    Last Updated:Jun 17, 2026

    Grant a RAM user full access to Cloud Architect Design Tools (CADT) so that the RAM user can automatically create a VPC when creating a Cloud Phone instance group.

    Background

    When you create a Cloud Phone instance group, Cloud Phone can automatically create a VPC for you. This feature relies on Cloud Architect Design Tools (CADT). If you use a RAM user to create a Cloud Phone instance group, you must grant the RAM user full access to CADT. Otherwise, the instance group creation fails.

    Procedure

    Attach the required policy to the RAM user.

    1. Log on to the RAM console with the Alibaba Cloud account that owns the RAM user.

    2. In the left navigation pane, choose IdentitiesUser.

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

    4. In the Grant Permission panel, configure the following settings and click OK.

      1. In the Resource Scope section, select Account.

      2. In the Policies section, search for and select the AliyunCADTFullAccess system policy.

    Results

    After the policy is attached, the RAM user can create a Cloud Phone instance group with the option to automatically create a VPC.
