Verwendung DescribeTasks mit einem AWS SDK oder CLI

Beispiel 1: So beschreiben Sie eine einzelne Aufgabe

Im folgenden Beispiel für describe-tasks werden die Details einer Aufgabe in einem Cluster abgerufen. Sie können die Aufgabe angeben, indem Sie entweder die ID oder den vollständigen ARN der Aufgabe verwenden. Dieses Beispiel nutzt den vollständigen ARN der Aufgabe.

aws ecs describe-tasks \
    --cluster MyCluster \
    --tasks arn:aws:ecs:us-east-1:123456789012:task/MyCluster/4d590253bb114126b7afa7b58EXAMPLE
