Container Service for Kubernetes:Create an encrypted computing cluster and node pool

Last Updated:Jun 16, 2026

Protect data-in-use with Intel SGX hardware isolation for workloads such as blockchain and key management.

ACK-TEE is a cloud-native confidential computing platform built on Intel SGX 2.0. It isolates data and code in a Trusted Execution Environment (TEE) inaccessible to applications, the BIOS, OS, kernel, administrators, operators, cloud providers, and all hardware except the CPU.

Prerequisites

Step 1: Create an encrypted computing cluster

  1. Log on to the ACK console. In the left navigation pane, click Clusters.

  2. Click Cluster Templates, select Confidential Computing Cluster, and click Create.

  3. On the ACK Managed Cluster page, configure the cluster.

    Key parameters for an encrypted computing cluster. For all parameters, see ACK managed cluster parameters.

    Parameter

    Description

    Confidential Computing

    Enable encrypted computing.

    Zone

    Only instances in the following Instance Family support encrypted computing: security-enhanced compute-optimized c7t, security-enhanced general-purpose g7t, and security-enhanced memory-optimized r7t. Ensure the selected zone offers these types. See Overview of instance families that are available for purchase.

    Skip creating a node pool in this step. For node pool parameters, see Step 2: Create an encrypted computing node pool.

Step 2: Create an encrypted computing node pool

  1. On the ACK Clusters page, click the name of your cluster. In the left navigation pane, click Nodes > Node Pools.

  2. Click Create Node Pool and configure the node pool.

    Key parameters for an encrypted computing node pool. For all parameters, see Create a node pool.

    Parameter

    Description

    Confidential Computing

    Enable encrypted computing.

    Container Runtime

    Only containerd is supported.

    Scaling Mode

    When enabled, the node pool automatically scales out based on resource usage.

    Instance-related parameters

    Select a security-enhanced instance type: c7t (compute-optimized), g7t (general-purpose), or r7t (memory-optimized).

    Remote attestation on these instances supports only DCAP, not legacy EPID. If your application uses EPID, migrate to DCAP.

    Expected Number of Nodes

    The initial number of nodes. Set to 0 to skip node creation.

    Operating System

    • Cluster version 1.30 and later: Alibaba Cloud Linux 3.2104 LTS 64-bit (Container-optimized) or Alibaba Cloud Linux 3.2104 LTS 64-bit.

    • Cluster versions earlier than 1.30: Alibaba Cloud Linux 2.xxxx 64-bit UEFI Edition only.

    Node Labels

    Add labels to cluster nodes.

    ECS Tags

    Add tags to ECS instances.

    After creation, the node pool Status changes to Active.

What to do next

After deployment, see Develop and build SGX 2.0 applications by using an SDK to build and deploy a sample SGX 2.0 application with the TEE-SDK.
