Per descrivere una coda di lavoro

Questo esempio descrive la coda dei HighPriority lavori.

Comando:

aws batch describe-job-queues --job-queues HighPriority

Output:

{
    "jobQueues": [
        {
            "status": "VALID",
            "jobQueueArn": "arn:aws:batch:us-east-1:012345678910:job-queue/HighPriority",
