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

Updated on 2024-10-30 GMT+08:00

Symptom

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.

Solution

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 System-defined permissions for UCS

Role/Policy Name

Description

Type

UCS FullAccess

Administrator permissions for UCS. Users with these permissions can perform all operations on UCS resources, for example, creating permission policies and security policies.

System-defined policy

UCS CommonOperations

Common user permissions for UCS. Users with these permissions can create workloads, distribute traffic, and perform other operations.

System-defined policy

UCS CIAOperations

Administrator permissions for UCS Container Intelligent Analysis.

System-defined policy

UCS ReadOnlyAccess

Read-only permissions for UCS (except for Container Intelligent Analysis).

System-defined 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 Admin, Operator, and Viewer roles of each UCS function.

NOTE:

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.

Fleets

Admin

  • Creating and deleting a fleet
  • Registering a Huawei Cloud cluster (CCE cluster or CCE Turbo cluster) , on-premises cluster, or attached cluster
  • Unregistering a cluster
  • Adding a cluster to or removing a cluster from a fleet
  • Associating permission policies with a cluster or fleet
  • Enabling cluster federation and performing federation management operations (such as creating a federated workload and creating domain name access)

UCS FullAccess

Viewer

Querying clusters and fleets or their details

UCS ReadOnlyAccess

Huawei Cloud cluster

Admin

Read-write permissions on Huawei Cloud clusters and all Kubernetes resource objects (such as nodes, workloads, jobs, and Services)

UCS FullAccess + CCE Administrator

Developer

Read-write permissions on Huawei Cloud clusters and most Kubernetes resource objects and read-only permissions on Kubernetes resource objects such as namespaces and resource quotas

UCS CommonOperations + CCE Administrator

Viewer

Read-only permissions on Huawei Cloud clusters and all Kubernetes resource objects (such as nodes, workloads, jobs, and Services)

UCS ReadOnlyAccess + CCE Administrator

On-premises/Attached/Multi-cloud cluster

Admin

Read-write permissions on on-premises/attached/multi-cloud clusters and all Kubernetes resource objects (such as nodes, workloads, jobs, and Services)

UCS FullAccess

Developer

Read-write permissions on on-premises/attached/multi-cloud clusters and most Kubernetes resource objects and read-only permissions on Kubernetes resource objects such as namespaces and resource quotas

UCS CommonOperations + UCS RBAC (The list permission for namespaces is required.)

Viewer

Read-only permissions on on-premises/attached/multi-cloud clusters and all Kubernetes resource objects (such as nodes, workloads, jobs, and Services)

UCS ReadOnlyAccess + UCS RBAC (The list permission for namespaces is required.)

Image Repositories

Admin

All permissions on SoftWare Repository for Container (SWR), including creating organizations, uploading images, viewing images or their details, and downloading images

SWR Administrator

Permissions

Admin

  • Creating and deleting a permission policy
  • Viewing permissions or their details
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.

Policy Center

Admin

  • Enabling Policy Center
  • Creating and disabling a policy
  • Querying policies
  • Viewing policy implementation details

UCS FullAccess

Viewer

Viewing policies and their implementation details of fleets and clusters with Policy Center enabled
