Manage Serverless Kubernetes clusters using the Alibaba Cloud CLI

When you complete this tutorial, the following resources are created by default:

• NAT Gateway
  • Number of instances: 1
  • Billing method: pay-as-you-go

Execute the following command to create a Serverless Kubernetes cluster:

aliyun cs POST /clusters --header "Content-Type=application/json" --body "$(cat create.json)"

The parameters for creating the Serverless Kubernetes cluster are saved in the create.json file. The code is as follows:

{
      "cluster_type": "Ask",
      "name": "example-serverless-kubernetes",
      "region_id": "cn-shanghai",
      "private_zone": false,
      "vpc_id": "",
      "vswitch_id": ""
}

You can customize your Serverless Kubernetes cluster using the following parameters:

• cluster_type

  • The cluster type. For a Serverless Kubernetes cluster, set this parameter to 'Ask'.

• name

  • The name of the cluster. The name can contain uppercase letters, lowercase letters, Chinese characters, digits, and hyphens.

• region_id

  • The ID of the region where you want to create the cluster.

• private_zone

  • Specifies whether to enable PrivateZone.

• vpc_id

  • The VPC ID. This parameter can be left empty. If you do not set this parameter, the system automatically creates a VPC with the 192.168.0.0/16 CIDR block. The system also automatically creates a NAT Gateway and configures SNAT rules in the VPC.
    Note You must set both vpc_id and vswitch_id, or leave them both empty.

• vswitch_id

  • The vSwitch ID. This parameter can be left empty. If you do not set this parameter, the system automatically creates a vSwitch with the 192.168.0.0/16 CIDR block.

After the cluster is created, the following output is displayed in the console:

{
    "cluster_id": "c61cf530524474386a7a******",
    "request_id": "348D4C9C-9105-4A1B-A86E-******",
    "task_id": "T-5ad724ab94a2b109e*****"
}

In the output, cluster_id is the unique ID of the cluster that you created.

Execute the following command to query information about the cluster that you created.

aliyun cs GET /clusters/<cluster_id>

After the command is executed, the following output is displayed in the console:

{
    "agent_version": "string",
    "cluster_id": "string",
    "created": "datetime",
    "external_loadbalancer_id": "string",
    "master_url": "string",
    "name": "string",
    "network_mode": "string",
    "region_id": "string",
    "security_group_id": "string",
    "size": "numbers",
    "state": "string",
    "updated": "datetime",
    "vpc_id": "string",
    "vswitch_id": "string",
    ...
}
