我需要在我的 Windows 实例初始化期间下载一个文件。为了测试这一点，我使用以下脚本来下载 Google 徽标（使用Windows 角色和功能模板的简化版本）：

{
  "AWSTemplateFormatVersion" : "2010-09-09",

  "Description" : "Test download.",

  "Resources" : {

    "InstanceSecurityGroup" : {
      "Type" : "AWS::EC2::SecurityGroup",
      "Properties" : {
        "GroupDescription" : "Enable RDP",
        "SecurityGroupIngress" : [
          {"IpProtocol" : "tcp", "FromPort" : "3389", "ToPort" : "3389", "CidrIp" : "0.0.0.0/0"}
        ]
      }
    },

    "WindowsServer": {
      "Type" : "AWS::EC2::Instance",
      "Metadata" : {
        "AWS::CloudFormation::Init" : {
          "config" : {
            "files" : {
              "c:\\test\\google-logo.png" : {
                "source" : "http://www.google.com/images/srpr/logo4w.png"
              }
            }
          }
        }
      },

      "Properties": {
        "InstanceType" : "m1.small",
        "ImageId" : "ami-bbf2e1cf",
        "SecurityGroups" : [ {"Ref" : "InstanceSecurityGroup"} ],
        "KeyName" : "POP",
        "UserData" : { "Fn::Base64" : { "Fn::Join" : ["", [
            "<script>\n",

            "cfn-init.exe -v -s ", { "Ref" : "AWS::StackId" }, 
            " -r WindowsServer",
            " --region ", { "Ref" : "AWS::Region" }, "\n",

            "</script>"
        ]]}}
      }
    },

    "WindowsServerWaitHandle" : {
      "Type" : "AWS::CloudFormation::WaitConditionHandle"
    },

    "WindowsServerWaitCondition" : {
      "Type" : "AWS::CloudFormation::WaitCondition",
      "DependsOn" : "WindowsServer",
      "Properties" : {
        "Handle" : {"Ref" : "WindowsServerWaitHandle"},
        "Timeout" : "1800"
      }
    }
  }
}

这完成了没有错误的执行......并且没有文件。我哪里错了？

乔纳森，

我尝试了您的模板，并且为我成功下载了文件。您可以检查实例上的 cfn 日志。他们在c:\cfn\log\. 我的 cfn-init.log 显示：
