CLI

AWS CLI

Para descrever uma fila de trabalhos

Este exemplo descreve a fila de trabalhos HighPriority.

Comando:

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

Saída:

{
    "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"
        }
    ]
}
