AWS CDK EC2.实例UserData....不坚持的：（

Question

我试图使用AWS CDK旋转一个ec2实例，在很大程度上它工作得很好，但我希望用户数据持久化，这样它就可以在每次引导时运行...令人恼火的是，这并没有文档化（在我可以找到的任何地方），我只是不知道在哪里/如何定义它。下面是我的代码，但是由于userdata是由forWindows()添加的，所以我不能添加xxx.addcommands(' true ')，因为forWindows（）将代码放在标记中...

// Instance details
const ssmaUserData = UserData.forWindows()
ssmaUserData.addCommands('mkdir -p C:/helloworld; ');

const ec2Instance = new ec2.Instance(this, 'SdkInstance', {
  vpc,
  instanceType: ec2.InstanceType.of(ec2.InstanceClass.T3, ec2.InstanceSize.NANO),
  machineImage: awsAMI,
  securityGroup: mySecurityGroup,
  vpcSubnets: {subnetType: ec2.SubnetType.PUBLIC},
  keyName: "EC2Connect",
  userData: ssmaUserData
});

我曾尝试使用ssmauserdata.addonexitcommands（“ true ”）及其变体，但没有成功，有人知道如何做到这一点吗？

下面的日志表明这不是用持久性运行的...

拿到了！因此，每当我使用userdata.forwindows()时，它将自动添加 标记，这意味着如果我定义了 ，它将包含标记······为了解决这个问题，我需要使用userdata.custom()。我已经测试了下面的代码，它是一个伟大的工作！

const script = `
<powershell>
  Start-Transcript -OutputDirectory C:/
  Write-Output HelloWorld
  Stop-Transcript
</powershell>
<persist>true</persist>
`;

const ssmaUserData = UserData.custom(script)

const ec2Instance = new ec2.Instance(this, 'SdkInstance', {
  vpc,
  instanceType: ec2.InstanceType.of(ec2.InstanceClass.T3, ec2.InstanceSize.NANO),
  machineImage: awsAMI,
  securityGroup: mySecurityGroup,
  vpcSubnets: {subnetType: ec2.SubnetType.PUBLIC},
  keyName: "EC2Connect",
  userData: ssmaUserData,
});
