タスク設定の保存

別のタスクの設定を再利用する場合に備えて、タスク設定をJSONファイルとして保存できます。ファイルにコピーするタスク設定は、タスクの概要の詳細セクションJSONにあります。

注記

他のタスクでタスク設定を再利用するときは、CloudWatchLogGroup と CloudWatchLogStream 属性を削除します。それ以外の場合は、次のエラーが表示されます。SYSTEMERRORMESSAGE:Task Settings CloudWatchLogGroup or CloudWatchLogStream cannot be set on create。

例えば、次のJSONファイルにはタスク用に保存された設定が含まれています。
