Permissions

Updated on 2024-10-09 GMT+08:00

If you need to assign different permissions to employees in your enterprise to access your cloud resources, IAM is a good choice for fine-grained permissions management. IAM provides identity authentication, permissions management, and access control, helping you secure access to your resources.

With IAM, you can use your Huawei Cloud account to create IAM users, and assign permissions to the users to control their access to specific resources. For example, some software developers in your enterprise need to use resources but cannot delete them or perform any high-risk operations. To achieve this result, you can create IAM users for the developers and grant them only the permissions for using resources.

You can skip this section if you do not need fine-grained permissions management.

IAM is a free service. You only pay for the resources in your account.

For more information about IAM, see IAM Service Overview.

GeminiDB Permissions

By default, new IAM users do not have any permissions assigned. To assign permissions to these new users, you need to add them to one or more groups, and attach permissions policies or roles to these groups.

GeminiDB is a project-level service deployed in specific physical regions. When assigning GeminiDB permissions to a user group, you need to specify region-specific projects where the permissions will take effect. If you select All projects, the permissions will be granted for all region-specific projects. To access GeminiDB, you need to switch to the region where you are authorized.

You can grant users permissions using roles and policies.

  • Roles: A type of coarse-grained authorization mechanism that provides only a limited number of service-level roles. When using roles to grant permissions, you also need to assign other dependent roles. Roles are not ideal for fine-grained authorization and secure access control.
  • Policies: A fine-grained authorization mechanism that defines permissions required to perform operations on specific cloud resources under certain conditions. This mechanism allows for more flexible policy-based authorization and more secure access control. For example, you can grant ECS users only the permissions for managing a certain type of ECSs. For API actions supported by GeminiDB, see Permissions Policies and Supported Actions.

Table 1 lists all the system-defined roles and policies supported by GeminiDB.

GeminiDB FullAccess

All permissions for GeminiDB

System-defined policy

To create a yearly/monthly instance, you need to configure the following CBC actions:

  • bss:balance:view
  • bss:balance:update
  • bss:order:view
  • bss:order:pay
  • bss:order:update
  • bss:renewal:view
  • bss:renewal:update

To unsubscribe from a yearly/monthly instance, you need to configure the following CBC action:

  • bss:unsubscribe:update

To use storage autoscaling, configure the following actions for IAM users:

  • Creating a custom policy:
    • iam:agencies:listAgencies
    • iam:agencies:createAgency
    • iam:permissions:listRolesForAgencyOnProject
    • iam:permissions:grantRoleToGroupOnProject
    • iam:roles:listRoles
    • iam:roles:createRole
  • Adding system role Security Administrator:
    1. Select a user group to which the user belongs.
    2. Click Authorize in the Operation column.
    3. Add the Security Administrator role.

GeminiDB FullAccess already contains the iam:agencies:listAgencies, iam:roles:listRoles, and iam:agencies:pass permissions.

GeminiDB is a region-level service, and IAM is a global service. If you want to grant GeminiDB FullAccess to a project, grant BSS ServiceAgencyReadPolicy (global service) to it as well. Granting GeminiDB FullAccess to all projects eliminates the need for additional configuration when using IAM actions.

BSS ServiceAgencyCreatePolicy contains the following permissions:

  • iam:agencies:createAgency
  • iam:permissions:grantRoleToAgency
