Creating a User and Granting SFS Permissions This section describes how to use IAM to implement fine-grained permissions control for your SFS resources. With IAM, you can: Create IAM users for employees based on your enterprise's organizational structure.
Obtaining Access Keys (AK/SK) To access SFS using access keys as an IAM user, the programmatic access must be enabled. For details, see Viewing or Modifying IAM User Information. When calling an API, you need to use the AK/SK to verify the signature.
For example, to obtain an IAM token in the CN-Hong Kong region, obtain the endpoint of IAM (iam.ap-southeast-1.myhuaweicloud.com) for this region and the resource-path (/v3/auth/tokens) in the URI of the API used to obtain a user token.
Table 1 SFS access control Method Description Reference Permissions control IAM permissions IAM permissions define which actions on your cloud resources are allowed or denied.
Policies that contain actions for both IAM and enterprise projects can be used and applied for both IAM and Enterprise Management. Policies that only contain actions for IAM projects can be used and applied to IAM only.
Creating an IAM User If you want to allow multiple users to manage your resources without sharing your password or private key, you can create users using IAM and grant permissions to the users.
IAM can be used free of charge. You pay only for the resources in your account. For more information about IAM, see IAM Service Overview. SFS Permissions By default, new IAM users do not have permissions assigned.
The token obtained from IAM is valid for only 24 hours. If you want to use one token for authentication, you can cache it to avoid frequently calling.
For security purposes, create Identity and Access Management (IAM) users and grant them permissions for routine management. User An IAM user is created by an account in IAM to use cloud services. Each IAM user has its own identity credentials (password and access keys).

An IAM user assigned the SFS Turbo ReadOnlyAccess policy does not need to have the VPC ReadOnlyAccess policy assigned explicitly. Viewing details of general purpose file systems depends on the VPC service. Ensure that the required role or policy has been configured.
If the permissions granted to an IAM user contain both "Allow" and "Deny", the "Deny" permissions take precedence over the "Allow" permissions.
{Endpoint} is the IAM endpoint and can be obtained from Regions and Endpoints. For details about API authentication, see Authentication. The following is an example response.
Protocol Type Only NFSv3 is supported currently. - VPC Select the IAM project to which the target VPC belongs and then select the target VPC. What Is an IAM Project? Select the VPC where the ECSs and VPC endpoint reside.
