AWS C# Lambda

View Code

This example creates an AWS Lambda function that does a simple .toUpper on the string input and returns it.

Deploying the App

To deploy your infrastructure, follow the steps below.

Prerequisites

  1. Install Pulumi
  2. Configure AWS Credentials

Steps

After cloning this repo, from this working directory, run these commands:

  1. Build and publish the lambda function, making the output available to our Pulumi program.

    dotnet publish ./DotnetLambda/src/DotnetLambda/
    
  2. Execute our Pulumi program to archive our published function output, and create our lambda.

    pulumi up -C ./pulumi
    
  3. Call our Lambda function from the AWS CLI with “foo” as the payload.

    aws lambda invoke \
    --function-name $(pulumi stack output Lambda -C ./pulumi) \
    --region $(pulumi config get aws:region -C ./pulumi) \
    --cli-binary-format raw-in-base64-out \
    --payload '"foo"' \
    output.json
    
    cat output.json # view the output file with your tool of choice
    # "FOO"
    
  4. From there, feel free to experiment. Simply making edits, rebuilding your handler, and running pulumi up will update your function.

  5. Afterwards, destroy your stack and remove it:

    pulumi destroy --yes
    pulumi stack rm --yes
