DescribeJobQueues
搭配 a AWS SDK 或 CLI 使用
下列程式碼範例示範如何使用 DescribeJobQueues
。
動作範例是大型程式的程式碼摘錄,必須在內容中執行。您可以在下列程式碼範例的內容中看到此動作:

描述任務佇列
此範例說明 HighPriority 任務佇列。
命令:
aws batch describe-job-queues --job-queues
HighPriority
輸出:
{ "jobQueues": [ { "status": "VALID", "jobQueueArn": "arn:aws:batch:us-east-1:012345678910:job-queue/HighPriority", "computeEnvironmentOrder": [ { "computeEnvironment": "arn:aws:batch:us-east-1:012345678910:compute-environment/C4OnDemand", "order": 1 } ], "statusReason": "JobQueue Healthy", "priority": 1, "state": "ENABLED", "jobQueueName": "HighPriority" } ] }
