Creating a User and Granting DMS for RabbitMQ Permissions

Use Identity and Access Management (IAM) to implement fine-grained permissions control over your Distributed Message Service (DMS) for RabbitMQ resources. With IAM, you can:

Create IAM users for personnel based on your enterprise's organizational structure. Each IAM user has their own identity credentials for accessing DMS for RabbitMQ resources.
Grant users only the permissions required to perform a given task based on their job responsibilities.
Entrust a HUAWEI ID or a cloud service to perform efficient O&M on your DMS for RabbitMQ resources.

If your HUAWEI ID meets your permissions requirements, you can skip this section.

This section describes the procedure for granting user permissions. Figure 1 shows the process flow.

DMS for RabbitMQ permissions policies are based on DMS. Therefore, when assigning permissions, select DMS permissions policies.

Prerequisites

Learn about the permissions (see System-defined roles and policies supported by DMS for RabbitMQ) supported by DMS for RabbitMQ and choose policies according to your requirements. For the system policies of other services, see System Permissions.

Process Flow

Figure 1 Process of granting DMS for RabbitMQ permissions

For the following example, create a user group on the IAM console,
and assign the DMS ReadOnlyAccess policy to the group.
Create an IAM user and add it to the created user group.
Log in as the IAM user and verify permissions.
In the authorized region, perform the following operations:
- Choose Service List > Distributed Message Service (for RabbitMQ). Then click Buy Instance on the console of DMS for RabbitMQ. If a message appears indicating that you have insufficient permissions to perform the operation, the DMS ReadOnlyAccess policy is in effect.
- Choose Service List > Elastic Volume Service. If a message appears indicating that you have insufficient permissions to access the service, the DMS ReadOnlyAccess policy is in effect.
