ACK Lingjun clusters are developed based on Intelligent Computing LINGJUN. Container Service for Kubernetes (ACK) can help you manage heterogeneous resources and schedule heterogeneous tasks in ACK Lingjun clusters. You can use ACK Lingjun clusters to gain heterogeneous computing capabilities in high-performance computing scenarios such as AI training and large language model inferences.
Prerequisites
Resource Access Management (RAM) is activated in the RAM console. Auto Scaling is activated in the Auto Scaling console.
CIDR blocks are planned for the cluster and the CIDR blocks do not overlap with each other. The CIDR block of the virtual private cloud (VPC) where the cluster is deployed, the Service CIDR block of the cluster, the CIDR block of the Lingjun connection instance used by the cluster, and the CIDR block of the Lingjun Virtual Private Datacenter (VPD) used by the cluster are the subsets of the following private CIDR blocks:
192.168.0.0/16,10.0.0.0/8, and172.16.0.0/12.
Billing
For more information about the billing of ACK Lingjun managed clusters, see Billing.
Limits
When you create an ACK cluster, take note of the following limits:
You must have an account balance of at least CNY 100. You must also pass real-name verification. Otherwise, you cannot create pay-as-you-go Elastic Compute Service (ECS) instances or Server Load Balancer (SLB) instances.
ACK Lingjun managed clusters support only VPCs.
By default, each account has specific quotas on cloud resources that can be created. You cannot create clusters if the quota is reached. Make sure that you have sufficient resource quotas before you create a cluster.
For more information about the resource quotas of ACK Lingjun managed clusters, see Resource quotas of ACK clusters.
By default, you can create at most 100 security groups with each account.
By default, you can create at most 60 pay-as-you-go SLB instances with each account.
By default, you can create at most 20 elastic IP addresses (EIPs) with each account.
Procedure
ACK Lingjun clusters can be created only in the Intelligent Computing LINGJUN console.
After you create an ACK Lingjun cluster, you can view the cluster on the Clusters page of the ACK console.
Click View Logs in the Actions column. On the Cluster Logs page, you can view the cluster log. To view detailed log data, click Stack events.
Click Details in the Actions column. On the details page of the cluster, click the Basic Information tab to view basic information about the cluster. You can also click the Connection Information tab to view information about how to connect to the cluster. The following information is displayed:
API Server Public Endpoint: the IP address and port that the Kubernetes API server of the cluster uses to provide services over the Internet. The endpoint allows you to manage the cluster by using kubectl or other tools on your client.
API Server Internal Endpoint: the IP address and port that the Kubernetes API server uses to provide services within the cluster. The IP address belongs to the SLB instance that is associated with the cluster.

Lingjun node pools facilitate the management of Intelligent Computing LINGJUN groups and Lingjun nodes. For more information, see Overview of Lingjun node pools.
You can manage the control planes and components on worker nodes in the ACK console. For more information, see Component overview.
Security and stability risks exist in outdated Kubernetes versions. We recommend that you refer to Support for Kubernetes versions to update your ACK Lingjun clusters that use outdated Kubernetes versions at the earliest opportunity. For more information about how to update ACK Lingjun clusters and the usage notes, see Update ACK Lingjun clusters.
