Esempi di metadati delle attività di Amazon ECS v4 per attività su Fargate
Gli esempi seguenti mostrano gli output di esempio degli endpoint dei metadati dei processi per i processi di Amazon ECS in esecuzione su AWS Fargate.
Dal container è possibile utilizzare il comando curl seguito dall'endpoint dei metadati dell'attività per eseguire una query sull'endpoint, ad esempio curl ${ECS_CONTAINER_METADATA_URI_V4}/task.
Esempio di risposta dei metadati del container
Quando si esegue una query sull'endpoint ${ECS_CONTAINER_METADATA_URI_V4} vengono restituiti solo i metadati relativi al container stesso. Di seguito è riportato un esempio di output.
