Creating a User and Granting DSS Permissions

This chapter describes how to use IAM to implement fine-grained permissions control for your DSS 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 DSS 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 DSS resources.

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

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

Prerequisites

Learn about the permissions (see DSS Permissions) supported by DSS and choose policies or roles according to your requirements.

Process Flow

Figure 1 Process for granting DSS permissions
  1. Create a user group and assign permissions to it.

    Create a user group on the IAM console, and attach the DSS ReadOnlyAccess policy to the group.

  2. Create a user and add it to a user group.

    Create a user on the IAM console and add the user to the group created in 1.

  3. Log in and verify permissions.

    Log in to the DSS console using the created user and verify that the user only has read permissions for DSS.

    • Choose Service List > Dedicated Distributed Storage Service. Then click Apply for Storage Pool on the DSS console. If a message appears indicating that you have insufficient permissions to perform the operation, the DSS 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 DSS ReadOnlyAccess policy has already taken effect.
