An ACK Lingjun cluster is a specialized cluster type in Container Service for Kubernetes (ACK) designed for Intelligent Computing LINGJUN. It helps you efficiently manage heterogeneous resources and provides flexible scheduling for optimal task allocation. This synergy enables powerful heterogeneous computing for high-performance scenarios, such as AI training and large model inference. This topic describes how to create an ACK Lingjun cluster.
Prerequisites
-
You have logged in to the RAM console and the Auto Scaling console to activate the required services.
-
You have planned the network segments and ensured that they do not conflict. The cluster's VPC CIDR block, the cluster's service CIDR block, the Lingjun interconnect CIDR block, and the Lingjun CIDR block must all be private CIDR blocks, such as
192.168.0.0/16,10.0.0.0/8, and172.16.0.0/12.
Billing
For more information about billing for managed ACK Lingjun clusters, see Billing.
Limitations
Note the following limitations:
-
Your account must have a balance of at least CNY 100 and pass identity verification. Otherwise, you cannot create pay-as-you-go ECS instances or Server Load Balancer (SLB) instances.
-
Managed ACK Lingjun clusters support only Virtual Private Cloud (VPC).
-
Each account has default quotas for cloud resources. If you exceed these quotas, cluster creation fails. Verify your quotas before you create a cluster.
-
For more information about the quota limits for managed ACK Lingjun clusters, see ACK cluster quota limits.
-
By default, you can create a maximum of 100 security groups per account.
-
By default, you can create a maximum of 60 pay-as-you-go Server Load Balancer (SLB) instances per account.
-
By default, you can create a maximum of 20 EIPs per account.
-
Procedure
-
Create a Lingjun cluster service with ACK.
ACK Lingjun clusters can be created only in the Intelligent Computing LINGJUN console.
-
After the cluster is created, view the target cluster on the Clusters page of the Container Service Management Console.
-
In the Actions column of the target cluster, click View Logs to go to the Cluster Logs page and view the cluster logs. You can also click Resource Stack Events to view more details.
-
In the Actions column, click Details. On the Basic Information and Connection Information tabs, you can view the cluster's basic information and connection information.
-
API Server Public Endpoint: The public endpoint (address and port) of the Kubernetes API server. You can use this endpoint to manage the cluster from your local machine by using tools such as kubectl.
-
API Server Internal Endpoint: The internal endpoint (address and port) of the Kubernetes API server. This IP address is provided by the Server Load Balancer (SLB) instance.
