Setup

Requires version 1.12 or higher to use go modules.

$ go version
go version go1.12.4 darwin/amd64

Since aws-sdk-go needs credentials, please set "dummy" if you use localstack.

$ cat ~/.aws/credentials

[dummy]
aws_access_key_id = dummy
aws_secret_access_key = dummy 

Run

Start docker for localstack.

$ docker-compose up -d
$ env GO111MODULE=on AWS_PROFILE=dummy go run main.go

Stop docker.

$ docker-compose down
