リファレンスまたはトップレベルのFn :: FindInMap

Question

とCloudFormationテンプレートは、私は以下のマッピングが

"Mappings": { 
"TimeBasedAutoScale" : { 
    "days" : { 
    "weekend" : {"0":"off","1":"off","2":"off","3":"off","4":"off","5":"off","6":"off","7":"off","8":"off","9":"off","10":"off","11":"off","12":"off","13":"off","14":"off","15":"off","16":"off","17":"off","18":"off","19":"off","20":"off","21":"off","22":"off","23":"off"}, 
    "weekday1" : {"0":"off","1":"off","2":"on","3":"on","4":"on","5":"on","6":"on","7":"on","8":"on","9":"on","10":"on","11":"on","12":"on","13":"on","14":"on","15":"on","16":"on","17":"on","18":"on","19":"on","20":"on","21":"on","22":"off","23":"off"}, 
    "weekday2" : {"0":"off","1":"off","2":"off","3":"on","4":"on","5":"on","6":"on","7":"on","8":"on","9":"on","10":"on","11":"on","12":"on","13":"on","14":"on","15":"on","16":"on","17":"on","18":"on","19":"on","20":"on","21":"on","22":"off","23":"off"} 
    } 
}, 
"TimeBasedSchedule": { 
    "6AMTimeBasedSchedule" : { 
    "schedule" : { 
     "Monday" : { "Fn::FindInMap" : [ "TimeBasedAutoScale", "days", "weekday1"]}, 
     "Tuesday" : { "Fn::FindInMap" : [ "TimeBasedAutoScale", "days", "weekday1"]}, 
     "Wednesday" :{ "Fn::FindInMap" : [ "TimeBasedAutoScale", "days", "weekday1"]}, 
     "Thursday" : { "Fn::FindInMap" : [ "TimeBasedAutoScale", "days", "weekday1"]}, 
     "Friday" : { "Fn::FindInMap" : [ "TimeBasedAutoScale", "days", "weekday1"]}, 
     "Saturday" : { "Fn::FindInMap" : [ "TimeBasedAutoScale", "days", "weekend"]}, 
    "Sunday" : { "Fn::FindInMap" : [ "TimeBasedAutoScale", "days", "weekend"]} 
    } 
}, 
"7AMTimeBasedSchedule" : { 
    "schedule" : { 
    "Monday" : { "Fn::FindInMap" : [ "TimeBasedAutoScale", "days", "weekday1"]}, 
    "Tuesday" : { "Fn::FindInMap" : [ "TimeBasedAutoScale", "days", "weekday1"]}, 
    "Wednesday" :{ "Fn::FindInMap" : [ "TimeBasedAutoScale", "days", "weekday1"]}, 
    "Thursday" : { "Fn::FindInMap" : [ "TimeBasedAutoScale", "days", "weekday1"]}, 
    "Friday" : { "Fn::FindInMap" : [ "TimeBasedAutoScale", "days", "weekday1"]}, 
    "Saturday" : { "Fn::FindInMap" : [ "TimeBasedAutoScale", "days", "weekend"]}, 
    "Sunday" : { "Fn::FindInMap" : [ "TimeBasedAutoScale", "days", "weekend"]} 
    } 
}} 

しかし、検証が失敗した私のテンプレートで定義されているとlooking at the docs後、私は理由を見ることができます。マッピング関数は、3段キーを必要とし、値は文字列またはリストのみになります。

reference以上のマッピングで上記を行うにはどうしますか？

マルチレベルマッピングを実行するには、内包されたFn::FindInMapの組み込み関数をResourcesまたはOutputsセクションに直接適用します。
