Replace the body of this method, and parameters, to suit your needs. 10 | 11 | After deploying your function you must configure an Amazon DynamoDB stream as an event source to trigger your Lambda function. 12 | 13 | ## Here are some steps to follow from Visual Studio: 14 | 15 | To deploy your function to AWS Lambda, right click the project in Solution Explorer and select *Publish to AWS Lambda*. 16 | 17 | To view your deployed function open its Function View window by double-clicking the function name shown beneath the AWS Lambda node in the AWS Explorer tree. 18 | 19 | To perform testing against your deployed function use the Test Invoke tab in the opened Function View window. 20 | 21 | To configure event sources for your deployed function, for example to have your function invoked when an object is created in an Amazon S3 bucket, use the Event Sources tab in the opened Function View window. 22 | 23 | To update the runtime configuration of your deployed function use the Configuration tab in the opened Function View window. 24 | 25 | To view execution logs of invocations of your function use the Logs tab in the opened Function View window. 26 | 27 | ## Here are some steps to follow to get started from the command line: 28 | 29 | Once you have edited your template and code you can deploy your application using the [Amazon.Lambda.Tools Global Tool](https://github.com/aws/aws-extensions-for-dotnet-cli#aws-lambda-amazonlambdatools) from the command line. 30 | 31 | Install Amazon.Lambda.Tools Global Tools if not already installed. 32 | ``` 33 | dotnet tool install -g Amazon.Lambda.Tools 34 | ``` 35 | 36 | If already installed check if new version is available. 37 | ``` 38 | dotnet tool update -g Amazon.Lambda.Tools 39 | ``` 40 | 41 | Execute unit tests 42 | ``` 43 | cd "SimpleDynamoDBFunction/test/SimpleDynamoDBFunction.Tests" 44 | dotnet test 45 | ``` 46 | 47 | Deploy function to AWS Lambda 48 | ``` 49 | cd "SimpleDynamoDBFunction/src/SimpleDynamoDBFunction" 50 | dotnet lambda deploy-function 51 | ``` 52 | -------------------------------------------------------------------------------- /src/LocalDynamoDbStream/aws-lambda-tools-defaults.json: -------------------------------------------------------------------------------- 1 | { 2 | "Information": [ 3 | "This file provides default values for the deployment wizard inside Visual Studio and the AWS Lambda commands added to the .NET Core CLI.", 4 | "To learn more about the Lambda commands with the .NET Core CLI execute the following command at the command line in the project root directory.", 5 | 6 | "dotnet lambda help", 7 | 8 | "All the command line options for the Lambda command can be specified in this file." 9 | ], 10 | 11 | "profile":"", 12 | "region" : "", 13 | "configuration": "Release", 14 | "framework": "netcoreapp2.1", 15 | "function-runtime": "dotnetcore2.1", 16 | "function-memory-size": 256, 17 | "function-timeout": 30, 18 | "function-handler": "LocalDynamoDbStream::LocalDynamoDbStream.Function::FunctionHandler" 19 | } 20 | -------------------------------------------------------------------------------- /test/LocalDynamoDbStream.Tests/FunctionTest.cs: -------------------------------------------------------------------------------- 1 | using System;
