使用Python CDK将dotnet 8代码捆绑到AWS Lambda函数

Question

我正在将 CDK 与 Python 结合使用，并尝试将 dotnet 8 代码构建、打包和部署为 lambda 函数。

下面的Python代码出现错误

Error: .NET binaries for Lambda function are not correctly installed in the /var/task directory of the image when the image was built.

from constructs import Construct
from aws_cdk import (
    Duration,
    Stack,
    aws_iam as iam,
    aws_lambda as lambda_
)
    csharp_lambda = lambda_.Function(
        self, "PythonCdkDotnetLambda",
        runtime=lambda_.Runtime.DOTNET_8,
        handler="helloworld::helloworld.Functions::ExecuteFunc",  
        code=lambda_.Code.from_asset("../path/to/src"),
    )

将 CDK 与 dotnet 一起使用时，有一个如下所示的捆绑选项，用于构建和打包代码

       //C# Code
       var buildOption = new BundlingOptions()
       {
           Image = Runtime.DOTNET_8.BundlingImage,
           User = "root",
           OutputType = BundlingOutput.ARCHIVED,
           Command = new string[]{
          "/bin/sh",
           "-c",
           " dotnet tool install -g Amazon.Lambda.Tools"+
           " && dotnet build"+
           " && dotnet lambda package --project-location helloworld/ --output-package /asset-output/function.zip"
           }
       };

如何为需要部署 dotnet 8 lambda 的 Python CDK 执行此 BundlingOption 操作，或者如何在使用 Python CDK 部署之前将 .net 代码构建到所需的二进制文件中？

我使用以下代码完成了此工作

        bundling_options = {
        "command": [
            "/bin/sh",
            "-c",
            " dotnet tool install -g Amazon.Lambda.Tools"+
            " && dotnet build" +
            " && dotnet lambda package --project-location helloworld/ --output-package /asset-output/function.zip"
        ],
        "image": lambda_.Runtime.DOTNET_8.bundling_image,
        "user": "root"
    }
            
    
    csharp_lambda = lambda_.Function(
        self, "PythonCdkDotnetLambda",
        runtime=lambda_.Runtime.DOTNET_8,
        handler="helloworld::helloworld.Functions::ExecuteFunc",  
        code=lambda_.Code.from_asset("../path/to/lambda", bundling=bundling_options),
    
    )
