Exemples de métadonnées de tâches Amazon ECS v4 pour les tâches sur Fargate
Les exemples suivants présentent des sorties de points de terminaison des métadonnées de tâche pour les tâches Amazon ECS exécutées sur AWS Fargate.
Depuis le conteneur, vous pouvez utiliser curl suivi du point de terminaison des métadonnées de la tâche pour interroger le point de terminaison, par exemple curl ${ECS_CONTAINER_METADATA_URI_V4}/task.
Exemple de réponse de métadonnées du conteneur
Lors de l'interrogation du point de terminaison ${ECS_CONTAINER_METADATA_URI_V4}, seules les métadonnées sur le conteneur lui-même vous sont renvoyées. Voici un exemple de sortie.
