AWS C# Lambda

This example lives in the pulumi/examples repository. Check out just this directory to use it:

$ git clone --filter=blob:none --sparse https://github.com/pulumi/examples pulumi-examples
$ git -C pulumi-examples sparse-checkout set aws-cs-lambda
$ cd pulumi-examples/aws-cs-lambda

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

Prerequisites#

1. Install Pulumi
2. Configure AWS credentials
3. Install .NET

Deploying the example#

1. Build and publish the Lambda function, making the output available to the Pulumi program:

   dotnet publish ./DotnetLambda/src/DotnetLambda/ -c Release

2. Create a new stack and set the AWS region to deploy into:

   pulumi stack init dev -C ./pulumi
   pulumi config set aws:region us-east-1 -C ./pulumi

3. Deploy the stack to archive the published function output and create the Lambda:

   pulumi up -C ./pulumi

4. Call the 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"

From there, feel free to experiment. Simply making edits, rebuilding your handler, and running pulumi up will update your function.

Cleaning up#

Once you’re finished experimenting, you can destroy your stack and remove it to avoid incurring any additional cost:

pulumi destroy -C ./pulumi
pulumi stack rm -C ./pulumi
