#### [ CLI ]

**AWS CLI**  
**描述任務佇列**  
此範例描述 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"
        }
    ]
}
```
