aws-cloudformation - 如何在生成竞价实例时避免使用队列选项？

Question

我正在使用此 cloudformation 模板来创建 Spot 实例，它按预期工作。

https://github.com/shantanuo/cloudformation/blob/master/updated/linux_training.tpl.txt

我想要的唯一更改是从此处的类型中删除“Fleet”部分...

Type: 'AWS::EC2::SpotFleet

原因:当我尝试停止实例时，收到一条消息“无法停止队列实例”。

如何使用“正常”或默认选项购买现货实例？

(AWS 用户界面)向导允许我生成可以根据需要停止和启动的现货实例。从 cloudformation 模板中寻找相同的功能。

根据评论中的建议，我已将模板修改为如下所示。它按预期工作。但它只会创建一个"template"。我仍然需要登录控制台才能使用模板启动新实例。我需要自动化端到端流程。

Parameters:
  LatestAmiId:
    Type: 'AWS::SSM::Parameter::Value<AWS::EC2::Image::Id>'
    Default: /aws/service/ami-amazon-linux-latest/amzn2-ami-minimal-hvm-arm64-ebs
  OksoftSG:
    Type: 'AWS::EC2::SecurityGroup::Id'
  KeyName:
    Type: 'AWS::EC2::KeyPair::KeyName'
  MyInstanceType:
    Type: String
    Default: r6g.medium
    AllowedValues:
      - r6g.medium
      - r6g.4xlarge
      - r6g.12xlarge
  MyIpAddress:
    Type: String
 
Resources:
  MySpotInstance:
    Type: 'AWS::EC2::LaunchTemplate'
    Properties:
      LaunchTemplateData:
        ImageId: !Ref LatestAmiId
        KeyName: !Ref KeyName
        SecurityGroupIds: 
          - !Ref OksoftSG
        InstanceType: !Ref MyInstanceType

        BlockDeviceMappings:
          - DeviceName: /dev/xvda
            Ebs:
              DeleteOnTermination: true
              VolumeType: standard
              VolumeSize: 400

        InstanceMarketOptions: 
          MarketType: spot
          SpotOptions:
            InstanceInterruptionBehavior: stop
            SpotInstanceType: persistent

  MyInstance:
    Type: 'AWS::EC2::Instance'
    Properties:
      "LaunchTemplate" : 
        LaunchTemplateId: !Ref MySpotInstance
        Version: !GetAtt MySpotInstance.LatestVersionNumber

当我删除 cloudformation 模板时，它不会删除它创建的 Spot 请求。

更新:

答案中提到的代码仅适用于Linux服务器。当我尝试启动 Windows 服务器时，出现错误:

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

我使用了这个模板:

以下是使用持久现货请求创建 LaunchTemplate 的工作示例，该示例基于模板创建实例。在持久现货请求上运行的实例可以停止，但不能终止(一旦有现货，就会启动替代实例):
