Json 云形成-设备索引不能为空
我一直在尝试让两个实例加入一个域，一个是dc。代码来自其中一个模板，但是它不允许我在修改后运行它。 当DC01实例启动时，我发现错误DeviceIndex不能为空。 这是DC01的代码Json 云形成-设备索引不能为空,json,amazon-web-services,amazon-ec2,amazon-cloudformation,Json,Amazon Web Services,Amazon Ec2,Amazon Cloudformation,我一直在尝试让两个实例加入一个域，一个是dc。代码来自其中一个模板，但是它不允许我在修改后运行它。 当DC01实例启动时，我发现错误DeviceIndex不能为空。 这是DC01的代码 { "Resources": { "DC1": { "Type": "AWS::EC2::Instance", "Properties": { "BlockDeviceMappings": [
