问题

我正在使用AWS CDK（Typescript版本）创建一个AutoScalingGroup：

    const asg = new autoscaling.AutoScalingGroup(this, 'ASG', {
      instanceType: ec2.InstanceType.of(
        ec2.InstanceClass.T2,
        ec2.InstanceSize.MICRO
      ),
      machineImage: ami,
      minCapacity: 2,
      maxCapacity: 5,
      securityGroup: securityGroup,
      vpc,
      role: role,
    });

一切正常，我有2个实例：

然而，让我非常惊讶的是，CDK在标记此方法为弃用时使用了Launch配置：

我该如何解决使用AutoScalingGroup时出现的问题？

如果可能的话，你能给我一个示例代码吗？

The AutoScalingGroup construct accepts to pass the launchTemplate parameter.

https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_autoscaling.AutoScalingGroup.html#launchtemplate

You need to pass there the object of the ILaunchTemplate interface described here: https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_ec2.ILaunchTemplate.html

Without creating a launch template explicitly, you'll always use the old launch configurations. My guess is that AWS doesn't make new templates default for the backward compatibility of CDK.

自动扩展组构造函数接受传递 launchTemplate 参数。

https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_autoscaling.AutoScalingGroup.html#launchtemplate

您需要在此处传递 ILaunchTemplate 接口的对象，该接口在此处描述：https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_ec2.ILaunchTemplate.html

如果没有显式创建启动模板，则始终将使用旧的启动配置。我猜测 AWS 之所以不将新模板设为默认值，是为了保证与 CDK 的向后兼容性。
