【问题标题】：AWS CloudFormation: Unable to import resources of type SubnetRouteTableAssociation, VPCGatewayAttachment and RouteAWS CloudFormation：无法导入 SubnetRouteTableAssociation、VPCGatewayAttachment 和 Route 类型的资源
【发布时间】：2020-10-10 07:41:37
【问题描述】：

我正在尝试使用 CloudFormation 模板创建网络资源，但是当我导入模板时出现以下错误：

资源导入不支持以下资源类型：AWS::EC2::SubnetRouteTableAssociation,AWS::EC2::VPCGatewayAttachment,AWS::EC2::Route,AWS::EC2::Route

知道原因是什么。在我的 CF 模板的代码下方：

【解决方案1】：

您的模板中几乎没有错误。

最重要的是，您不需要具有 172.32.0.0/16 本地规则的 Route1。这始终是默认创建的。

TestDevSubnetRouteTableAssociation 的参数中也缺少 !Ref。

我修改了您的模板，以便现在可以部署。我没有检查它的功能，只检查它是否部署。

您可以将其用作将来修改的基础。：

感谢您指出这一点。我还发现我最初的错误不是由于我的模板中的错误，而是因为我在尝试创建堆栈时在控制台上选择了错误的选项。我选择“导入现有资源”而不是使用“使用新资源”
@BalkrishanNagpal 没问题。如果您觉得我的回答有帮助，一旦您对它感到满意，我们将不胜感激。
