Best Practices for ACK Cluster Authorization System - Container Service for Kubernetes

Authorization system

RAM authorization uses system and custom policies to control access to ACK API operations and Alibaba Cloud services. It covers:

Creating, viewing, upgrading, and deleting clusters
Creating, modifying, and scaling node pools
Managing authorization
Monitoring clusters and collecting logs and events

RBAC authorization controls access to Kubernetes resources within a cluster using Kubernetes RBAC. It covers add, delete, modify, and query operations on:

Workloads: Deployment, StatefulSet, DaemonSet, Job, CronJob, pod, and ReplicaSet
Network resources: Service, Ingress, and NetworkPolicy
Storage resources: persistent volume (PV), persistent volume claim (PVC), and StorageClass
Configuration: Namespace, ConfigMap, and Secret

Prerequisites

Verify the following:

The RAM user or role is designated as a permission administrator (not required for Alibaba Cloud account owners).

Use case 1: Authorize read-only administrators

Assign the predefined Read-only Administrator RBAC role for read-only access to Kubernetes resources across all namespaces. No RAM authorization required.

Assign the Read-only Administrator role

ACK console

See Grant RBAC permissions to a RAM user or role.

Alibaba Cloud CLI

Call GrantPermissions with role_name set to admin-view. Verify with DescribeUserPermission.

aliyun cs POST /permissions/users/234xxxxxxxx --header "Content-Type=application/json;" --body "[{\"cluster\":\"c24xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx\",\"is_custom\":false,\"role_name\":\"admin-view\",\"role_type\":\"cluster\"}]"

Terraform

resource "alicloud_cs_kubernetes_permissions" "default" {
  uid = alicloud_ram_user.user.id
  permissions {
    cluster     = alicloud_cs_managed_kubernetes.default.id
    role_type   = "cluster"
    role_name   = "admin-view"
    namespace   = ""
    is_custom   = false
    is_ram_role = false
  }
}

Use case 2: Authorize O&M engineers

O&M engineers require both RAM and RBAC authorization to manage clusters and applications.

Step 1: RAM authorization

ACK provides two system-managed RAM policies:

Policy	Access level
`AliyunCSFullAccess`	Full read/write access to all ACK API operations
`AliyunCSReadOnlyAccess`	Read-only access to all ACK API operations

In the RAM console, attach the policy to the RAM user or role. See Grant permissions to a RAM user and Grant permissions to a RAM role.

For fine-grained control, create a custom policy. See Use RAM to grant the permissions to access clusters and cloud resources. The following example covers all O&M operations. For each action, see Action description.

  ]
}

Replace xxxxx in acs:cs:*:*:cluster/xxxxx with your cluster ID.

For ACK API actions, see [Product Changes] ACK API enhances user authentication and API overview.

Step 2: RBAC authorization

After RAM authorization, assign a predefined RBAC role. The following table describes all predefined roles and their scope.

Predefined role	RBAC permissions on cluster resources	When to use
Administrator	Full read/write access to all Kubernetes resources in all namespaces, plus cluster-level resources: nodes, PVs, namespaces, and resource quotas	Unrestricted cluster access. For permission management, assign the `cluster-admin` ClusterRole under Custom.
Read-only Administrator	Read-only access to all Kubernetes resources in all namespaces, plus cluster-level resources: nodes, PVs, namespaces, and resource quotas	Cluster-wide visibility without write access.
O&M Engineer	Read/write access to all console-visible resources in all namespaces; read and update access to nodes, PVs, and namespaces; read-only access to all other resources	Day-to-day cluster operations. No permission management.
Developer	Read/write access to console-visible resources, scoped to all namespaces or a specified set	Application deployment and management. Can be scoped to specific namespaces.
Restricted User	Read-only access to console-visible resources, scoped to all namespaces or a specified set	View-only access for developers or operators.
Custom	Determined by the ClusterRole you select. Review permissions before assigning. See Use custom RBAC roles to restrict resource operations in a cluster.	Fine-grained access control beyond the predefined roles.

Important

Assigning the cluster-admin ClusterRole grants the same permissions as the Alibaba Cloud account — full control over all resources in the cluster. Use caution.

To assign a role in the console:

Log on to the ACK console. In the left navigation pane, click Authorizations.
On the Authorizations page, click the RAM Users or RAM Roles tab. Find the target and click Modify Permissions.
Click +Add Permissions, select O&M Engineer for the target cluster and namespace, and click Submit.

RBAC

ACK automatically creates a ClusterRoleBinding. The following is the ClusterRole definition for the O&M Engineer role (cs:ops):

For fine-grained control, create a custom ClusterRole with Kubernetes RBAC and select it on the Authorizations page in the ACK console. See Use custom RBAC roles to restrict resource operations in a cluster.

Use case 3: Authorize developers

Developers require RBAC authorization for Kubernetes resources and read-only RAM access to the cluster.

Important

Complete RAM authorization before RBAC authorization. Developers must have at least read-only RAM permissions on the cluster for RBAC authorization to take effect.

Step 1: RAM authorization

Create a custom policy in the RAM console and attach it to the RAM user or role. See Grant access to clusters and cloud resources using RAM. Minimum read-only permissions:

{
  "Statement": [
    {
      "Action": [
        "cs:GetClusters",
        "cs:DescribeClusterDetail",
        "cs:GetClusterAuditProject",
        "cs:DescribeResourcesDeleteProtection"
      ],
      "Resource": "acs:cs:*:*:cluster/xxxxx",
      "Effect": "Allow"
    }
  ],
  "Version": "1"
}

Replace xxxxx with your cluster ID. For read-only access to all ACK clusters, use the AliyunCSReadOnlyAccess system policy.

Step 2: RBAC authorization

Log on to the ACK console. In the left navigation pane, click Authorizations.
On the Authorizations page, click the RAM Users or RAM Roles tab. Find the target and click Modify Permissions.
Click +Add Permissions, select Developer for the target cluster and namespace, and click Submit.

developer

ACK automatically creates a ClusterRoleBinding. The following is the ClusterRole definition for the Developer role (cs:ns:dev):

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole

For fine-grained control, create a custom ClusterRole with Kubernetes RBAC and select it on the Authorizations page in the ACK console. See Use custom RBAC roles to restrict resource operations in a cluster.

Use case 4: Authorize permission administrators

Permission administrators manage RBAC permissions for other RAM users and roles. By default, a RAM user or role cannot grant RBAC permissions — the Authorizations page displays: The current RAM user account has no permission to manage authorizations. Contact the Alibaba Cloud account owner or authorized RAM user to request permission.

This requires both RAM and RBAC authorization.

Step 1: RAM authorization

The RAM policy must include permissions to:

Query RAM users and roles in the Alibaba Cloud account
Query RBAC permissions of a RAM user or role
Grant RBAC permissions to other RAM users or roles

In the RAM console, attach the following policy to the RAM user or role:

{
  "Statement": [
    {
      "Action": [
        "ram:ListRoles",
        "ram:ListUserBasicInfos",
        "cs:GetClusters",
        "cs:DescribeUserPermission",
