编排模板基本语法说明

映射（Mappings）

映射是一个 Key-Value 映射表。在模板的 Resources 和 Outputs 中，可以使用 Fn::FindInMap 内部函数，通过指定 Key 而获取映射表的 Value。

语法

映射由　Key-Value 对组成。其中 Key 和 Value 可以为字符串类型或者数字类型。如果声明多个映射，用逗号分隔开。每个映射的名称不能重复。

{
    "Mappings" : {
        "Mapping01" : {
            "Key01" : {
                "Name" : "Value01",
                "Name" : "Value01-1"
            },
            "Key02" : {
                "Name" : "Value02",
                "Name" : "Value02-1"
            },
            "Key03" : {
                "Name" : "Value03",
                "Name" : "Value03-1"
            }
    }
}
