Create an ACK Lingjun managed cluster - Container Service for Kubernetes

Container Service for Kubernetes (ACK) Lingjun managed clusters are developed based on Intelligent Computing Lingjun. ACK creates and maintains the control planes of ACK Lingjun managed clusters for you. This eliminates the need to manually build and configure clusters. ACK Lingjun managed clusters can meet the requirements of enterprises in large-scale production environments. This topic describes how to create an ACK Lingjun managed cluster.

Prerequisites

Resource Access Management (RAM) is activated in the RAM console. Auto Scaling is activated in the Auto Scaling console.

Note Plan CIDR blocks of the cluster. The CIDR blocks cannot overlap with each other. The virtual private cloud (VPC) CIDR block, Service CIDR block, Border Gateway Protocol (BGP) CIDR block, and VPD CIDR block must be private CIDR blocks. The VPD CIDR block must be a subset of the following CIDR blocks: 192.168.0.0/16, 10.0.0.0/8, and 172.16.0.0/12.

Background information

For more information about the billing rules of ACK Lingjun managed clusters, see Billing.

Limits

When you create an ACK Lingjun managed cluster, take note of the following limits:

You must have at least CNY 100 in your account balance. 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 virtual private clouds (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

You can create ACK Lingjun managed clusters only in the Intelligent Computing Lingjun console.

Verify the result

After the cluster is created, you can find the cluster on the Clusters page in the ACK console.
Click View Logs in the Actions column. On the Log Center page, you can view the cluster log. To view detailed log information, 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.
