How Do I Configure the Access Permission for Each Function of the UCS Console?

Background

The functions of the UCS console are controlled by IAM. When an unauthorized user accesses a page on the UCS console, an error message is displayed, indicating that the user does not have the access permission or permission authentication fails.

Solutions

The administrator needs to grant users the permissions for using functions of the UCS console. IAM system policies (including UCS FullAccess, UCS CommonOperations, UCS CIAOperations, and UCS ReadOnlyAccess) are used to define user permissions.

Table 1 UCS system permissions

System Role/Policy Name

Description

Type

UCS FullAccess

UCS administrator with full permissions, including creating permissions policies and security policies

System policy

UCS CommonOperations

Common UCS user with permissions for creating workloads, distributing traffic, and other operations

System policy

UCS CIAOperations

UCS Container Intelligent Analysis (CIA) administrator with full permissions

System policy

UCS ReadOnlyAccess

Read-only permissions on UCS (except for CIA)

System policy

Services on Huawei Cloud are interdependent, and UCS depends on other cloud services to implement some functions, such as image repository and domain name resolution. Therefore, the preceding system policies are often used together with roles or policies of other cloud services for refined permission granting. When granting permissions to IAM users, the administrator must comply with the principle of least privilege. Table 2 lists the minimum permissions required by the administrator, operation, and read-only permissions of each UCS function.

For details about how to grant IAM system policies and UCS RBAC permissions to users, see UCS Resource Permissions and Kubernetes Resource Permissions in a Cluster, respectively.

NOTE:

When creating a permission policy, you need to grant the IAM ReadOnlyAccess permission (read-only permissions on IAM) to IAM users to obtain the IAM user list.

  • Creating and disabling a policy
  • Querying policies
  • Viewing policy implementation details

UCS FullAccess

Viewer

For fleets and clusters with Policy Center enabled, users with this permission can view policies and policy implementation details.
