LocalStack: AWS Resource

Experiment AWS resource creation locally

Introduction

In short, this post will guide us on practicing Terraform and AWS resource creation locally. By the end, we should have a local environment set up for experimenting with Terraform.

After setting up the environment, we will perform two operations:

1. Create an S3 bucket.
2. Upload a local file to the S3 bucket.

Pre-requisite

• OS : Ubuntu
• Python: download
• Docker: download
• AWS CLI: download
• Terraform: download

wget -O- https://apt.releases.hashicorp.com/gpg | sudo gpg --dearmor -o /usr/share/keyrings/hashicorp-archive-keyring.gpg
echo "deb [signed-by=/usr/share/keyrings/hashicorp-archive-keyring.gpg] https://apt.releases.hashicorp.com $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/hashicorp.list
sudo apt update && sudo apt install terraform

• Terraform local : download
• Local AWS CLI:

pip install awscli-local

Fire Up

Let’s start all the components and configure.

1. Start localstack container

# Pull docker image
docker run --rm -it -p 4566:4566 -p 4510-4559:4510-4559 localstack/localstack

localstack start -d

2. To configure AWS, you can use the following configurations:

Note: region should be us-east-1

# mhr@mhr$ aws configure 

AWS Access Key ID []: test
AWS Secret Access Key []: test
Default region name [us-east-1]: us-east-1
Default output format [json]: json

Resource Creation (locally)

Let’s create an S3 bucket and verify its existence in our localstack.

If we currently check with awslocal, we won't find a bucket named my-bucket.

my-bucket

As we can see there are no s3 bucket called my-bucket.

1. Create a file main.tf

resource "aws_s3_bucket" "test-bucket" {
  bucket = "my-bucket"
}

2. Initialize and Apply terraform changes.

tflocal init

Initialize terraform

tflocal apply

Apply changes

Voilà!!!! .. our s3 bucket my-bucket has been created on our local stack docker container.

We can upload and check if it really works.

Uploading A file to our new s3 bucket

Conclusions

I hope this post helps you set up a local environment for practicing basic AWS resource creation. Feel free to experiment with the configurations and create more advanced resources.

Thank you.
