Question

我想启动一个实例并添加多个安全组。我正在使用AWS参数。

使用！Ref（请参阅下文），我收到一个错误：SecurityGroupIds属性的值必须为String列表类型

    "SecurityGroupID": {
        "Description": "Select one Security Group ID (Must be available to the VPC)",
        "Type": "List<AWS::EC2::SecurityGroup::Id>"
    },

它与Select一起使用，但仅返回列表中的第一个SG。我想在SecurityGroupIds中获得SG的完整列表。

“ SecurityGroupIds”：[{“ Fn :: Select”：[“ 0”，{“ Ref”：“ SecurityGroupID”}]}]]，

谢谢

您指定SecurityGroupID参数是一个列表，但是随后在列表构造中引用了该参数。因此，您正在尝试将列表列表分配给仅接受列表的属性。

更改您的Properties属性，使其看起来像这样（如@jarmod在评论中所说）：

"Properties" : {
    "SecurityGroupIds" : {"Ref": "SecurityGroupID"},
}

如果您将参数命名为SecurityGroupIDs，也很容易混淆，以使其明显是列表。

如何启动具有从列表中选择的多个SG的实例
