Utilizzare DescribeJobQueues con un AWS SDK o CLI
I seguenti esempi di codice mostrano come utilizzareDescribeJobQueues.
Gli esempi di operazioni sono estratti di codice da programmi più grandi e devono essere eseguiti nel contesto. È possibile visualizzare questa operazione nel contesto nel seguente esempio di codice:

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",
"computeEnvironmentOrder": [
{
"computeEnvironment": "arn:aws:batch:us-east-1:012345678910:compute-environment/C4OnDemand",
"order": 1
}
],
"statusReason": "JobQueue Healthy",
"priority": 1,
"state": "ENABLED",
"jobQueueName": "HighPriority"
}
