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.
aws cli & awscli-local in case you want to check what has been "deployed" in localstack
Start the Lambda
Run make localstack
Run make terraform
Use the output api_gw_id to compose the url
Curl the hello world endpoint: curl --location --request GET "http://localhost:4566/restapis/$(tflocal -chdir=infra/terraform output -raw api_gw_id)/test/_user_request_/hello-world"
Run integration tests
Make sure you don't have a running localstack container.
