Question

我已经尝试了this question中的所有故障排除方法。

  <div className={list} onMouseOverCapture={e => this.catchMouseOver(e)}>
    //... some other divs that does not play any role in this example
    <div className={status1} title={'100%'}>
      <div className={security}>
        <i className={sprite} />
      </div>
    </div>
    <div className={status2} title={'20%'}>
      //... A lot of such divs with child divs like the first one `status1` div
    <div className={statusN} title={'0%'}>
  </div>

test.txt文件未在C：\ Temp文件夹中创建。

C：\ ProgramData \ Amazon \ EC2-Windows \ Launch \ Log \ UserdataExecution.log：

const getTooltipContainer = ({ target }) => {
  const aim = target.hasAttribute('title') && target
  console.log('target', aim ) // but it does not return div with `title` attribute, 
                              // only last max depper children div instead
}

但是我可以在"UserData": { "Fn::Base64": { "Fn::Join": [ "", [ "<powershell>\n", "New-Item C:\\Temp\\test.txt -ItemType file \n", "</powershell>\n", "<persist>true</persist>" ] ] } }

看到脚本

Answer 1

TLDR；通过在用于创建自定义AMI的实例上运行SysPrep，我的userdata脚本现在在首次启动时由以下用户执行：     云的形成。


使用EC2Launch设置应用程序运行Sysprep：



在Amazon EC2控制台中，找到或创建Windows Server 2016 AMI。

从AMI启动Windows实例。

连接到Windows实例并对其进行自定义。

搜索并运行EC2LaunchSettings应用程序。它位于以下     目录默认为：C:\ProgramData\Amazon\EC2-Windows\Launch\Settings。

根据需要选择或清除选项。这些设置存储在LaunchConfig.json中     文件。     6.使用Sysprep选择关机。



为Windows Server 2016配置Sysprep之后   可以安全地创建AMI的自定义映像。添加新创建的   AMI到CFN模板后执行成功。

Answer 2

对于自定义AMI的用户数据，已经禁用以使其能够在powershell中按照以下命令运行。

C：\ ProgramData \ Amazon \ EC2-Windows \ Launch \ Scripts \ InitializeInstance.ps1 –计划

然后userdata脚本应该起作用。

Answer 3

运行命令并获取 AMI

C:\ProgramData\Amazon\EC2-Windows\Launch\Scripts\InitializeInstance.ps1 –Schedule

AWS Cloudformation Userdata Powershell脚本未在自定义Windows Server AMI上运行
