与 AWS SDK或DescribeJobQueues
一起使用 CLI
以下代码示例演示如何使用 DescribeJobQueues
。
操作示例是大型程序的代码摘录,必须在上下文中运行。在以下代码示例中,您可以查看此操作的上下文:
- CLI
-
- AWS CLI

描述任务队列
此示例描述了 HighPriority 任务队列。
命令:
aws batch describe-job-queues --job-queues
HighPriority
输出:
{ "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" } ] }
