This topic describes how to use Resource Access Management (RAM) to manage permissions for a RAM user. This topic also describes how to manage RAM users, create resource groups, grant permissions, and configure access control. In this example, an e-commerce website project is used.

Prerequisites

If you need to use RAM to manage permissions for a RAM user, you can use the sample template that is provided by Resource Orchestration Service (ROS). You can use this template to build environments in which you can manage RAM users and grant permissions. To build the environments, go to the Manage Account Permissions with RAM page. Before you build the environments, make sure that the following operations are performed:

  • You are authorized to access Elastic Compute Service (ECS), Virtual Private Cloud (VPC), ApsaraDB RDS, Object Storage Service (OSS), and RAM.
  • The resource groups for development, production, and test environments are created. The IDs of the resource groups are obtained. For more information about how to create resource groups, see Create a resource group.

Step 1: Create a stack

  1. Log on to the ROS console.
  2. In the left-side navigation pane, click Solution Center.
  3. On the page that appears, find the Manage Account Permissions with RAM template.
  4. Click Create Stack.
  5. In the Configure Template Parameters step, specify Stack Name and configure the following parameters.
