AWS Lambda for Go

tests build-lambda-zip Go Reference GoCard codecov

Libraries, samples, and tools to help Go developers develop AWS Lambda functions.

To learn more about writing AWS Lambda functions in Go, go to the official documentation

Getting Started

// main.go
package main

import (
	"github.com/aws/aws-lambda-go/lambda"
)

func hello() (string, error) {
	return "Hello λ!", nil
}

func main() {
	// Make the handler available for Remote Procedure Call by AWS Lambda
	lambda.Start(hello)
}

Building your function

Preparing a binary to deploy to AWS Lambda requires that it is compiled for Linux and placed into a .zip file.

For developers on Linux and macOS

# Remember to build your handler executable for Linux!
GOOS=linux GOARCH=amd64 go build -o main main.go
zip main.zip main

For developers on Windows

Windows developers may have trouble producing a zip file that marks the binary as executable on Linux. To create a .zip that will work on AWS Lambda, the build-lambda-zip tool may be helpful.

Get the tool

go.exe install github.com/aws/aws-lambda-go/cmd/build-lambda-zip@latest

Use the tool from your GOPATH. If you have a default installation of Go, the tool will be in %USERPROFILE%\Go\bin.

in cmd.exe:

set GOOS=linux
set GOARCH=amd64
set CGO_ENABLED=0
go build -o main main.go
%USERPROFILE%\Go\bin\build-lambda-zip.exe -o main.zip main

in Powershell:

$env:GOOS = "linux"
$env:GOARCH = "amd64"
$env:CGO_ENABLED = "0"
go build -o main main.go
~\Go\Bin\build-lambda-zip.exe -o main.zip main

Deploying your functions

To deploy your function, refer to the official documentation for deploying using the AWS CLI, AWS Cloudformation, and AWS SAM.

Event Integrations

The event models can be used to model AWS event sources. The official documentation has detailed walkthroughs.
