使用cloudformation的带有持久性请求的Windows spot实例

Question

当我尝试使用此模板启动windows服务器时，我得到一个错误:

Property validation failure: [Value of property {/LaunchTemplateData} does not match type {Object}]

我使用的模板是:

Parameters:
1InstanceType:
Type: String
Default: t2.small
AllowedValues:
- t2.small
- m3.medium
- m3.xlarge
- i3.xlarge
2SecurityGroup:
Type: 'AWS::EC2::SecurityGroup::Id'
3KeyName:
Type: 'AWS::EC2::KeyPair::KeyName'
4LatestAmiId:
Type: 'AWS::SSM::Parameter::Value<AWS::EC2::Image::Id>'
Default: /aws/service/ami-windows-latest/Windows_Server-2016-English-Full-Base
Resources:
Ec2LaunchTemplate:
Type: AWS::EC2::LaunchTemplate
Properties:
LaunchTemplateName: WindowsDesktop
LaunchTemplateData:
- ImageId: !Ref 4LatestAmiId
InstanceType: !Ref 1InstanceType
SecurityGroups:
- GroupId: !Ref 2SecurityGroup
KeyName: !Ref 3KeyName
InstanceMarketOptions:
MarketType: spot
SpotOptions:
SpotInstanceType: persistent
InstanceInterruptionBehavior: stop

类似的代码适用于linux服务器。使用cloudformation似乎无法创建具有持久性请求的Windows spot实例(或模板)。

Answer 1

这个错误意味着您的LaunchTemplateData不是一个对象，但在您的示例中它是一个列表。这是因为在ImageId之前有额外的-。所以应该是:

Resources:
Ec2LaunchTemplate:
Type: AWS::EC2::LaunchTemplate
Properties:
LaunchTemplateName: WindowsDesktop
LaunchTemplateData:
ImageId: !Ref 4LatestAmiId
InstanceType: !Ref 1InstanceType
SecurityGroups:
- GroupId: !Ref 2SecurityGroup
KeyName: !Ref 3KeyName
InstanceMarketOptions:
MarketType: spot
SpotOptions:
SpotInstanceType: persistent
InstanceInterruptionBehavior: stop
