示例

• 创建集群

  以下示例指定master节点数为3、worker节点数为3，用于创建一个的新的Kubernetes集群实例。有关更多参数详情，请参见创建Kubernetes集群。

  package main
  
  import (
      "fmt"
      "github.com/aliyun/alibaba-cloud-sdk-go/services/cs"
  )
  
  func main() {
      // 创建并初始化client实例。
      // 更多方法请见 https://github.com/aliyun/alibaba-cloud-sdk-go/blob/master/docs/2-Client-CN.md。
      client,err := cs.NewClientWithAccessKey("your_region", "your_access_key_id", "your_access_key_secret")
      if err != nil {
          // Handle exceptions
          fmt.Println("err")
          panic(err)
      }
      // 创建请求。
      request := cs.CreateCreateClusterRequest()
      // 设置创建集群参数。
      // 更多参数细节请见 https://help.aliyun.com/document_detail/87525.html。

      // 创建请求。
      response,err := client.CreateCluster(request)
      if err != nil {
          panic(err)
      }
      // 判断是否成功。
      if response.IsSuccess() {
          fmt.Printf("%s | Failed reate cluster, response is %s",response.RequestId, response.GetHttpContentString())
      } else {
          fmt.Printf("%s | Create cluster successfully",response.RequestId)
      }
  }

• 集群扩容

  以下示例将在集群ID为cf68eabc的集群中扩容一台类型为ecs.c5.xlarge的节点。有关更多参数详情，请参见扩容Kubernetes多可用区集群。

  package main
  
  import (
      "fmt"
      "github.com/aliyun/alibaba-cloud-sdk-go/services/cs"
  )
  
  func main() {
      // 创建并初始化client实例。
      client,err := cs.NewClientWithAccessKey("your_region", "your_access_key_id", "your_access_key_secret")
      if err != nil {
          // Handle exceptions
          fmt.Println("err")
          panic(err)
      }
      // 创建集群扩容请求，并设置参数。
      request := cs.CreateScaleClusterRequest()
      // 更多参数细节请见 https://help.aliyun.com/document_detail/123927.html。
      request.PathParams = map[string]string{
          "ClusterId": "cf68eabc",
      }
      request.FormParams = map[string]string{
          "key_pair":"common", // KeyPair
          "vswitch_ids":`["vsw-uf684tfrpwup8gcsw****"]`,
          "worker_instance_types":`["ecs.c5.xlarge"]`,
          "worker_system_disk_category":"cloud_efficiency",

          "worker_data_disk":"false",
          "worker_data_disks": `[{"category": "cloud_ssd", "size": 500}]`,
          "count":"1",
      }
  
      // 创建请求。
      response,err := client.ScaleCluster(request)
      if err != nil {
          panic(err)
      }
      // 判断是否成功。
      if response.IsSuccess() {
          fmt.Printf("%s | Failed to scale cluster, response is %s",response.RequestId, response.GetHttpContentString())
      } else {
          fmt.Printf("%s | Successfully scale cluster",response.RequestId)
      }
  }

• 添加已有ECS实例至Kubernetes集群

  以下示例将实例ID为i-xxxx和i-yyyy的ECS添加到集群cf68eabc中。有关更多参数详情，请参见添加已有ECS实例到Kubernetes集群。

  package main
  
  import (
      "fmt"
      "github.com/aliyun/alibaba-cloud-sdk-go/services/cs"
  )
  
  func main() {
      // 创建并初始化client实例。
      client,err := cs.NewClientWithAccessKey("your_region", "your_access_key_id", "your_access_key_secret")
      if err != nil {
          // Handle exceptions
          fmt.Println("err")
          panic(err)
      }
      // 创建请求，并设置参数。
      request := cs.CreateAttachInstancesRequest()
      // 更多参数细节请见 https://help.aliyun.com/document_detail/86807.html。
      request.PathParams = map[string]string{
          "ClusterId": "cf68eabc",
      }
      request.FormParams = map[string]string{
          "password": "Hello1234",
          "instances": `["i-xxxx","i-yyyy"]`,
      }
  
      // 创建请求。
      response,err := client.AttachInstances(request)
      if err != nil {
          panic(err)
      }
      // 判断是否成功。
      if response.IsSuccess() {
          fmt.Printf("Failed to attach intstance to cluster, response is %s", response.GetHttpContentString())
      } else {
          fmt.Printf("Successfully attach intstance to cluster",)
      }
  }
