Creating AWS S3 Bucket

AWS Authentication

Before creating resources, you need to configure AWS credentials for Terraform to authenticate with AWS APIs.

Authentication Methods

1. AWS CLI Configuration: aws configure
2. Environment Variables: AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY
3. IAM Roles: For EC2 instances or AWS services
4. AWS Profiles: Named credential profiles

S3 (Simple Storage Service)

Object storage service that offers scalability, data availability, security, and performance.

Tasks for Practice

Prerequisites

1. Create AWS Account: Sign up for AWS free tier if you don’t have an account
2. Install AWS CLI: Download and install from AWS official website
3. Configure Credentials: Set up your AWS access keys

AWS CLI Installation

Check your system architecture first:

# Linux/macOS
uname -m

# Windows PowerShell
$env:PROCESSOR_ARCHITECTURE

Official Website: https://aws.amazon.com/cli/

Windows:

# Using MSI installer (recommended)
# Download from: <https://awscli.amazonaws.com/AWSCLIV2.msi>

# Using winget
winget install Amazon.AWSCLI

# Using chocolatey
choco install awscli

macOS:

# Using official installer
curl "<https://awscli.amazonaws.com/AWSCLIV2.pkg>" -o "AWSCLIV2.pkg"
sudo installer -pkg AWSCLIV2.pkg -target /

# Using Homebrew
brew install awscli

Ubuntu/Debian:

# Update package index
sudo apt update

# Install AWS CLI v2 (choose based on your architecture)
# For x86_64
curl "<https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip>" -o "awscliv2.zip"

# For ARM64
curl "<https://awscli.amazonaws.com/awscli-exe-linux-aarch64.zip>" -o "awscliv2.zip"

unzip awscliv2.zip
sudo ./aws/install

# Verify installation
aws --version

Authentication Setup

Method 1: AWS CLI Configuration

aws configure

Enter your:

• AWS Access Key ID
• AWS Secret Access Key
• Default region (e.g., us-east-1)
• Default output format (json)

Method 2: Environment Variables

export AWS_ACCESS_KEY_ID="your-access-key"
export AWS_SECRET_ACCESS_KEY="your-secret-key"
export AWS_DEFAULT_REGION="us-east-1"

Tasks to Complete

1. Get familiar with Terraform AWS documentation
   • Visit: https://registry.terraform.io/providers/hashicorp/aws/latest
   • Explore S3 resource documentation
2. Create AWS resources using terraform
   • S3 bucket with unique name
3. Practice Terraform commands
   • Initialize the working directory
   • Plan the infrastructure changes
   • Apply the configuration
   • Verify resources in AWS Console

Important Notes

• Resource Names: S3 bucket names must be globally unique
• Regions: Ensure you’re working in your intended AWS region
• Costs: Monitor AWS costs, even in free tier
• Cleanup: Always destroy resources when done practicing

Common Commands

# Initialize Terraform
terraform init

# Validate configuration
terraform validate

# Plan changes
terraform plan

# Apply changes
terraform apply

# Show current state
terraform show

# Destroy resources
terraform destroy

Troubleshooting Tips

• Check AWS credentials are properly configured
• Verify region settings match your intended deployment location
• Ensure S3 bucket names are unique and follow naming conventions
• Review AWS CloudTrail for API call logs if needed

Solution…

terraform {
  required_providers {
    aws = {
      source = "hashicorp/aws"
      version = "~> 6.0"
    }
  }
}

provider "aws" {
  # Configuration options
    region = "us-east-1"
}

# Create a S3 bucket
resource "aws_s3_bucket" "tf_test_baivab_bucket" {
  bucket = "my-tf-test-baiv-bucket-101"

  tags = {
    Name        = "My bucket"
    Environment = "Dev"
  }
}
