AWS Golang 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 below steps.


  1. Install Pulumi
  2. Configure AWS Credentials
  3. Clone aws-go-lambda


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

  1. Build the handler:

    • For developers on Linux and macOS:

      make build
    • For developers on Windows:

      • Get the build-lambda-zip tool:

        set GO111MODULE=on
        go.exe get -u
      • Use the tool from your GOPATH:

        set GOOS=linux
        set GOARCH=amd64
        set CGO_ENABLED=0
        go build -o handler\handler handler\handler.go
        %USERPROFILE%\Go\bin\build-lambda-zip.exe -o handler\ handler\handler
  2. Create a new Pulumi stack, which is an isolated deployment target for this example:

    pulumi stack init


  3. Set the required configuration variables for this program:

    pulumi config set aws:region us-east-1


  4. Execute the Pulumi program to create our lambda:

    pulumi up


  5. Call our Lambda function from the AWS CLI with “foo” as the payload:

    aws lambda invoke \
    --function-name $(pulumi stack output lambda) \
    --region $(pulumi config get aws:region) \
    --cli-binary-format raw-in-base64-out \
    --payload '"foo"' \
    cat output.json # view the output file with your tool of choice
    # "FOO"


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

  7. Afterwards, destroy your stack and remove it:

    pulumi destroy --yes
    pulumi stack rm --yes
