# LocalStack Pro Samples
This repository contains sample projects that can be deployed on your local machine using [LocalStack Pro](https://localstack.cloud/).
Each example in the repository is prefixed with the name of the AWS service being used. For example, the `elb-load-balancing` directory contains examples that demonstrate how to use the Elastic Load Balancing service with LocalStack. Please refer to the sub directories for more details and instructions on how to start the samples.
## Prerequisites
* [Docker](https://docs.docker.com/get-docker/)
* [`awslocal` CLI](https://docs.localstack.cloud/user-guide/integrations/aws-cli/)
* [Serverless](https://www.serverless.com/framework/docs/getting-started)
* [Terraform](https://developer.hashicorp.com/terraform/downloads)
* `make` & `jq`
## Configuration
Some of the samples require LocalStack Pro features. Please make sure to properly configure the `LOCALSTACK_AUTH_TOKEN` environment variable. You can find your Auth Token on the [LocalStack Web Application](https://app.localstack.cloud/workspace/auth-token) and you can refer to our [Auth Token documentation](https://docs.localstack.cloud/getting-started/auth-token/) for more details.

## Checking out a single sample
To check out a single sample, you can use the following commands:
```bash
mkdir localstack-samples && cd localstack-samples
git init
git remote add origin -f [email protected]:localstack/localstack-pro-samples.git
git config core.sparseCheckout true
echo >> .git/info/sparse-checkout
git pull origin master
```
The above commands use `sparse-checkout` to only pull the sample you are interested in. You can find the name of the sample directory in the table above.
# Developer Notes
## Makefiles for samples
All samples should have a Makefile to unify the execution of the otherwise heterogeneous samples.
It needs to fulfill two criteria:
- The sample should be executable independently, since it can be checked out on its own (see [Checking out a single sample](#checking-out-a-single-sample)).
- It should contain a `test-ci` target to be executed automatically within the CI pipeline. This step needs to take care of all infrastructure tasks (starting/stopping/logs/etc) in addition to any sample commands executed.
A typical Makefile looks like this:
```bash
export AWS_ACCESS_KEY_ID ?= test
export AWS_SECRET_ACCESS_KEY ?= test
export AWS_DEFAULT_REGION=us-east-1
SHELL := /bin/bash
usage: ## Show this help
@fgrep -h "##" $(MAKEFILE_LIST) | fgrep -v fgrep | sed -e 's/\\$$//' | sed -e 's/##//'
install: ## Install dependencies
@which localstack || pip install localstack
@which awslocal || pip install awscli-local
## install whatever else you need, like node modules, python packages, etc.
@test -e node_modules || npm install
@test -e .venv || (python3 -m venv .venv; source .venv/bin/activate; pip install -r requirements.txt)
run: ## Run the actual sample steps/commands. This assumes LocalStack is up and running.
./run.sh
start: ## Start LocalStack in detached mode
localstack start -d
stop: ## Stop the Running LocalStack container
@echo
localstack stop
ready: ## Make sure the LocalStack container is up
@echo Waiting on the LocalStack container...
@localstack wait -t 30 && echo LocalStack is ready to use! || (echo Gave up waiting on LocalStack, exiting. && exit 1)
logs: ## Save the logs in a separate file, since the LS container will only contain the logs of the last sample run.
@localstack logs > logs.txt
test-ci: ## Execute the necessary targets in the correct order for an automatic execution.
make start install ready run; return_code=`echo $$?`;\
make logs; make stop; exit $$return_code;
.PHONY: usage install run start stop ready logs test-ci
```
