CreateJobQueue 搭配 AWS SDK或 使用 CLI

使用單一運算環境建立低優先順序任務佇列

此範例會建立名為 的任務佇列 LowPriority ，該任務佇列使用 M4Spot 運算環境。

命令：

aws batch create-job-queue --cli-input-json file://<path_to_json_file>/LowPriority.json

JSON 檔案格式：

{
  "jobQueueName": "LowPriority",
  "state": "ENABLED",
  "priority": 10,
  "computeEnvironmentOrder": [
    {
      "order": 1,
      "computeEnvironment": "M4Spot"
    }
  ]
}

輸出：

{
    "jobQueueArn": "arn:aws:batch:us-east-1:012345678910:job-queue/LowPriority",
    "jobQueueName": "LowPriority"
}

使用兩個運算環境建立高優先順序任務佇列

此範例會建立名為 的任務佇列 HighPriority ，其使用順序為 1 的 C4OnDemand 運算環境，以及順序為 2 的 M4Spot 運算環境。排程器會先嘗試在 C4OnDemand 運算環境中放置任務。

命令：

aws batch create-job-queue --cli-input-json file://<path_to_json_file>/HighPriority.json

JSON 檔案格式：

{
  "jobQueueName": "HighPriority",
  "state": "ENABLED",
  "priority": 1,
  "computeEnvironmentOrder": [
    {
      "order": 1,
      "computeEnvironment": "C4OnDemand"
    },
    {
      "order": 2,
      "computeEnvironment": "M4Spot"
    }
  ]
}

輸出：

{
    "jobQueueArn": "arn:aws:batch:us-east-1:012345678910:job-queue/HighPriority",
    "jobQueueName": "HighPriority"
}
