Provision and Manage AWS EC2 Instances and S3 Bucket Using Terraform IaC

Posted by

Introduction

Terraform is an Infrastructure-as-Code (IaC) tool that allows you to manage your infrastructure in a declarative way. Amazon Web Services (AWS) provides a wide range of cloud services that can be used to build scalable and reliable applications. In this blog post, we will explore how to use Terraform to provision and manage AWS EC2 instances and S3 buckets. We will walk through the process of creating a Terraform configuration file to define the necessary AWS resources, including the AWS provider, EC2 instances, and S3 buckets. By the end of this tutorial, you will have a basic understanding of how to use Terraform to manage your AWS infrastructure as code.

Prerequisites

Before we get started, you'll need the following:

  • A basic understanding of Terraform and AWS
  • Terraform installed on your local machine
  • An AWS account with administrative privileges
  • An access key and secret key for your AWS account

Step 1: Configure AWS provider

The first step is to configure the AWS provider in your Terraform configuration. Create a new directory for your Terraform configuration files:

$ mkdir aws-terraform

$ cd aws-terraform

Next, create a new file called main.tf and add the following code to define your AWS provider:




This Terraform configuration file defines an AWS provider with the access_key, secret_key, and region parameters set to your AWS credentials and the desired region for your infrastructure.


Step 2: Provision EC2 instances


Now that you have your AWS provider defined, it's time to provision your EC2 instances. Add the following code to your main.tf file:


Above Terraform configuration file defines an aws_instance resource with the ami parameter set to the Amazon Machine Image (AMI) ID of the desired instance image and the instance_type parameter set to the desired instance type. The tags block sets the name of the instance to "example-instance" for easy identification.

Step 3: Create S3 bucket


Now, let's create an S3 bucket for storing and managing your objects. Add the following code to your main.tf file:


This Terraform configuration file defines an aws_s3_bucket resource with the bucket parameter set to the desired name of the S3 bucket and the acl parameter set to "private" for security purposes.

Step 4: Deploy your infrastructure

Now that your Terraform configuration is defined, it's time to deploy your infrastructure. Run the following commands in your terminal:

$ terraform init

$ terraform apply

Terraform will download the AWS provider plugin and apply your configuration, creating a new EC2 instance and S3 bucket in your AWS account.

Conclusion

In this blog post, we explored how to use Terraform to provision and manage AWS EC2 instances and S3 buckets. By using Terraform to manage your AWS infrastructure, you can easily version, test, and deploy your infrastructure as code. Terraform provides a powerful and flexible way to manage your AWS resources, making it easier to scale your applications and manage your infrastructure.
