使用 .NET Core CLI 部署 Amazon Lambda 项目

Amazon Toolkit for Visual Studio 包含适用于 Visual Studio 的 Amazon Lambda .NET 内核项目模板。您可以使用 .NET Core 命令行界面（CLI）部署 Visual Studio 中构建的 Lambda 函数。

先决条件

在使用.NET Core CLI 部署 Lambda 函数之前，您必须满足以下先决条件：

使用 .NET Core CLI 部署 Lambda 函数时，以下相关主题可能会有所帮助：

列出可通过 .NET Core CLI 使用的 Lambda 命令

要列出可通过 .NET Core CLI 使用的 Lambda 命令，请执行以下操作。

C:\Lambda\AWSLambda1\AWSLambda1>dotnet lambda --help
    Amazon Lambda Tools for .NET Core functions
    Project Home: https://github.com/aws/aws-lambda-dotnet
    .
    Commands to deploy and manage Lambda functions:
    .
            deploy-function         Deploy the project to Lambda
            invoke-function         Invoke the function in Lambda with an optional input
            list-functions          List all of your Lambda functions
            delete-function         Delete a Lambda function
            get-function-config     Get the current runtime configuration for a Lambda function
            update-function-config  Update the runtime configuration for a Lambda function
    .
    Commands to deploy and manage Amazon serverless applications using Amazon CloudFormation:
    .
            deploy-serverless       Deploy an Amazon serverless application
            list-serverless         List all of your Amazon serverless applications
            delete-serverless       Delete an Amazon serverless application
    .
    Other Commands:
    .
            package                 Package a Lambda project into a .zip file ready for deployment
    .
    To get help on individual commands, run the following:

            dotnet lambda help <command>

从 .NET Core CLI 发布 .NET Core Lambda 项目

以下说明假定您已在 Visual Studio 中创建 Amazon Lambda .NET 内核函数。

成功完成后，将显示消息 New Lambda function created (新 Lambda 函数已创建)。

C:\Lambda\AWSLambda1\AWSLambda1>dotnet lambda deploy-function
Executing publish command
... invoking 'dotnet publish', working folder 'C:\Lambda\AWSLambda1\AWSLambda1\bin\Release\netcoreapp1.0\publish'
... publish: Publishing AWSLambda1 for .NETCoreApp,Version=v1.0
... publish: Project AWSLambda1 (.NETCoreApp,Version=v1.0) will be compiled because expected outputs are missing
... publish: Compiling AWSLambda1 for .NETCoreApp,Version=v1.0
... publish: Compilation succeeded.

Creating new Lambda function
Select IAM Role that Lambda will assume when executing function:
    1) lambda_exec_LambdaCoreFunction
    2) *** Create new IAM Role ***

Updating code for existing function

在部署 Lambda 函数后，便可使用该函数。有关更多信息，请参阅如何使用 Amazon Lambda 的示例。

Lambda 会通过 Amazon CloudWatch 报告指标，自动为您监控 Lambda 函数。要对 Lambda 函数进行监控和问题排查，请参阅使用 Amazon CloudWatch 对 Amazon Lambda 函数进行监控和问题排查。
