This example deploys a complete serverless C# application using raw aws.apigateway.RestAPI, aws.lambda.Function and
aws.dynamodb.Table resources from @pulumi/aws. Although this doesn't feature any of the higher-level abstractions
from the @pulumi/cloud package, it demonstrates that you can program the raw resources directly available in AWS
to accomplish all of the same things this higher-level package offers.
The deployed Lambda function is a simple C# application, highlighting the ability to manage existing application code in a Pulumi application, even if your Pulumi code is written in a different language like JavaScript or Python.
The Lambda function is a C# application using .NET Core 2.1 (a similar approach works for any other language supported by AWS Lambda). To deploy the complete application:
# Create and configure a new stack
$ pulumi stack init testing
$ pulumi config set aws:region us-east-2
# Install dependencies
$ npm install
# Build the C# app
$ cd ./app
$ dotnet publish
$ cd ..
# Preview and run the deployment
$ pulumi up
