用于 cloudformation 启动模板的 cfn-init

Question

如何在 LaunchTemplate 中使用 cfn-init？这适用于 EC2 实例、自动扩展组中的 ECS 集群。

Metadata实例的部分在哪里，--resource传递给 cnf-init 的内容是什么？

LaunchTemplate:
  Type: AWS::EC2::LaunchTemplate
  Properties:
    LaunchTemplateName: !Sub ${AWS::StackName}-launch-template
    LaunchTemplateData: 
      SecurityGroups: 
        - !Ref DMZSecurityGroup
        - !Ref ECSSecurityGroup
      UserData:
        Fn::Base64:
          !Sub |
            #!/bin/bash -xe
            yum update -y aws-cfn-bootstrap
            /opt/aws/bin/cfn-init -v --stack ${AWS::StackName} --resource ??? --region ${AWS::Region}
            yum -y update

我对元数据的最佳猜测产生了错误：

    Property validation failure: [Encountered unsupported properties in {/LaunchTemplateData}: [Metadata]]

我在错误的嵌套级别有元数据，它应该与Type:和一起在最顶层，而Properties:不是在Properties:LaunchTemplateData:.

LaunchTemplate:
  Type: AWS::EC2::LaunchTemplate
  Metadata: 
    AWS::CloudFormation::Init: 
      config:
        files:
          /var/www/html/index2.html:
            content: TestString
  Properties:
    LaunchTemplateData: 
      SecurityGroupIds: 
        - !GetAtt DMZSecurityGroup.GroupId
        - !GetAtt ECSSecurityGroup.GroupId
      UserData:
        Fn::Base64:
          !Sub |
            #!/bin/bash -xe
            yum update -y aws-cfn-bootstrap
            /opt/aws/bin/cfn-init -v --stack ${AWS::StackName} --resource ECSLaunchTemplate --region ${AWS::Region}
            yum -y update
