Creating a User and Granting CDM Permissions

This chapter describes how to use Identity and Access Management (IAM) to implement fine-grained permissions control for your CDM resources. With IAM, you can:

Create IAM users for employees based on your enterprise's organizational structure. Each IAM user will have their own security credentials for accessing CDM resources.
Grant only the permissions required for users to perform a specific task.
Entrust a Huawei Cloud account or cloud service to perform efficient O&M on your CDM resources.

If your Huawei Cloud account does not require individual IAM users, skip this chapter.

This section describes the procedure for granting permissions (see Figure 1).

Process Flow

Figure 1 Process of granting CDM permissions

Create a user group and assign permissions
Create a user group on the IAM console, and attach the CDM ReadOnlyAccess policy to the group.
Create an IAM user.
Create a user on the IAM console and add the user to the group created in 1.
Log in and verify permissions.
Log in to the CDM console by using the user created, and verify that the user only has read permissions for CDM.
- Choose Service List > Cloud Data Migration. On the CDM console, view clusters. If no message appears indicating insufficient permissions to perform the operation, the CDM ReadOnlyAccess policy has already taken effect.
- Choose any other service in Service List. If a message appears indicating that you have insufficient permissions to access the service, the CDM ReadOnlyAccess policy has already taken effect.
