What is LocalStack?

LocalStack provides an easy-to-use test/mocking framework for developing Cloud applications. This means you can test AWS cloud resources locally on your machine.

Note: LocalStack supporting only AWS cloud stack.

LocalStack spins up the following core Cloud APIs on your local machine.

• ACM , API Gateway, CloudFormation, CloudWatch
• CloudWatch Logs, DynamoDB, DynamoDB Streams
• EC2, Elasticsearch Service, EventBridge (CloudWatch Events)
• Firehose, IAM, Kinesis, KMS, Lambda, Redshift
• Route53, S3, SecretsManager, SES, SNS
• SQS, SSM, StepFunctions, STS

Benefits of Using LocalStack

• Reduce Cost
• Test AWS Cloud Resource Locally
• Learn AWS Cloud Resource Locally
• Debug Locally

Let’s Start

We hope you have installed Docker on your system else you can check the following article to install Docker.

Docker-Compose.YML

Note: Starting with version 0.11.0, all APIs are exposed via a single edge service, which is accessible on http://localhost:4566 by default. If you look into the following file we have used EDGE_PORT=4566.

In the above file, We are creating 2 Services as below with default region us-east-1

1. Lambda
2. S3

If you run the following command

docker-compose up

You will see the LocalStack container is running successfully

How To Test Services

To check all the services type the following URL on your browser

http://localhost:4566/health

if you look at the above screenshot 4 services are running

1. lambda
2. logs
3. s3
4. cloud watch

But in our docker-compose.yml file, we have added only 2 services which are

1. lambda
2. s3

With lambda service logs and cloud watch service enabled by default.
