Golang で作った関数を AWS Lambda で動かす

package main

import (
	"fmt"

)

type Request struct {
	Value string `json:"value"`
}

type Response struct {
	Message string `json:"message"`
}

func echo(event Request) (Response, error) {
	return Response{Message: fmt.Sprintf("Request value is %s", event.Value)}, nil
}

func main() {
	lambda.Start(echo)
}

go mod init main

$ go mod init main
go: creating new go.mod: module main
go: to add module requirements and sums:
	go mod tidy

go mod tidy

GOOS=linux GOARCH=amd64 go build -o echo

zip handler.zip ./echo

$ ls
