阿里云容器服务ACK通过ACK Serverless集群运行Job任务-云淘科技

前提条件

• 创建ACK Serverless集群

• 通过kubectl连接Kubernetes集群

操作步骤

1. 通过kubectl客户端创建job.yaml文件，并拷贝以下内容到该文件。

   apiVersion: batch/v1
   kind: Job
   metadata:
     name: pi
   spec:
     template:
       spec:
         containers:
         - name: pi
           image: perl
           command: ["perl",  "-Mbignum=bpi", "-wle", "print bpi(2000)"]
           resources:
             requests:
               cpu: 16
               memory: 32Gi
         restartPolicy: Never
     backoffLimit: 4

2. 执行以下命令部署一个Job任务。

   kubectl apply -f job.yaml

3. 执行以下命令，查看Pod的运行状态。

   查看Pod的状态。

   kubectl get pod

   预期输出：

   NAME       READY   STATUS      RESTARTS   AGE
   pi-4f7w5   0/1     Completed   0          80s

   查看Pod的具体运行状态。

   kubectl describe pod

   预期输出：

   Name:               pi-4f7w5
   Namespace:          default
   Priority:           0
   PriorityClassName:  
   Node:               virtual-kubelet-cn-hongkong-b/10.10.66.169
   ...
   Events:
     Type    Reason                 Age   From          Message
     ----    ------                 ----  ----          -------
     Normal  SuccessfulMountVolume  114s  kubelet, eci  MountVolume.SetUp succeeded for volume "default-token-8k4jz"
     Normal  Pulling                113s  kubelet, eci  pulling image "perl"
     Normal  Pulled                 64s   kubelet, eci  Successfully pulled image "perl"
     Normal  Created                64s   kubelet, eci  Created container
     Normal  Started                64s   kubelet, eci  Started container

4. 可选：通过给Pod加上抢占式实例的Annotation，使用抢占式实例。

   关于抢占式实例Annotation的用法，请参见使用抢占式实例。

   apiVersion: batch/v1
   kind: Job
   metadata:
     name: pi
   spec:
     template:
       metadata:
         annotations:
           k8s.aliyun.com/eci-spot-strategy: SpotAsPriceGo
       spec:
         containers:
         - name: pi
           image: perl
           command: ["perl",  "-Mbignum=bpi", "-wle", "print bpi(2000)"]
           resources:
             requests:
               cpu: 16
               memory: 32Gi
         restartPolicy: Never
     backoffLimit: 4
