Go Lambda

This repository demonstrates an example on how to run a simple Go lambda with an AWS API Gateway on localstack. Here localstack is provisioned using tflocal (a localstack specific wrapper around Terraform). In addition, the repository contains an example on levaraging localstack in combination with ory/dockertest in order to integration test your Go Lambda.
