.NET-使用AWS CDK为.NET的低级CloudFormation资源构造标记EC2实例

虽然我们都在等待更高级别/手写的Construct可用于使用AWS CDK创建EC2实例,但我正在尝试使用自动生成的低级CloudFormation资源,网址为Amazon.CDK.AWS.EC2 NuGet package中的Amazon.CDK.AWS.EC2.cloudformation.InstanceResource_

我的测试应用程序是。Amazon.CDK.AWS.EC2 NuGet package作为唯一其他依赖项的.NET Core控制台应用程序。这是代码:

using System;
using System.Linq;

namespace AWSCDKEval
{
    class Program
    {
        static void Main(string[] args)
        {
            // Create a new app. The first argument is used to display a usage message for this app.
            var appArgs = new [] { $"dotnet ${nameof(AWSCDKEval)}" }
                .Concat(args)
                .ToArray();
            var app = new Amazon.CDK.App(appArgs);

            new TestStack(app, "test-aws-cdk-stack-1", new Amazon.CDK.StackProps());

            // Your app must write the return value of app.Run() to standard output. The `cdk init`
            // and `cdk synth` commands require this output.
            Console.WriteLine(app.Run());
        }
    }

    public class TestStack : Amazon.CDK.Stack
    {
        public TestStack(Amazon.CDK.App parent, string name, Amazon.CDK.IStackProps props) : base(parent, name, props)
        {
            new Amazon.CDK.AWS.EC2.cloudformation.InstanceResource_(
                this, 
                "testInstance1", 
                new Amazon.CDK.AWS.EC2.cloudformation.InstanceResourceProps
                {
                    ImageId = "ami-0f1155cc2cb6b0cfd", // Microsoft Windows Server 2016 Base
                    InstanceType = "t2.micro",
                    KeyName = "my_key",
                    Tags = new []
                    {
                        new Amazon.CDK.Tag { Key = "Name", Value = "test-instance-1" },
                        new Amazon.CDK.Tag { Key = "foo", Value = "bar" }
                    }
                });
        }
    }
}

然后,您编译项目并使用CDK将其synth放入CloudFormation模板中,除tags之外的所有设置都将其放入。

dotnet build <folder-with-code>
cdk synth --output <folder-where-to-write-cf-templates>

输出:

Resources:
    testInstance1:
        Type: 'AWS::EC2::Instance'
        Properties:
            ImageId: ami-0f1155cc2cb6b0cfd
            InstanceType: t2.micro
            KeyName: my_key
    CDKMetadata:
        Type: 'AWS::CDK::Metadata'
        Properties:
            Modules: '@aws-cdk/aws-ec2=0.9.1,@aws-cdk/aws-iam=0.9.1,@aws-cdk/cdk=0.9.1,@aws-cdk/cx-api=0.9.1,js-base64=2.4.9'

现在,我完全理解CDK处于起步阶段,不建议用于任何开发工作,但最好的部分是cloudformation命名空间下所有本机资源的可用性,我计划在CDK增长。

在正确方向上的任何帮助将不胜感激!

结果是,如果您使用typescript而不是任何C# .NET,则为currently a bug in AWS CDK and does work。我已经为此登录了issue
