Example Environment IaC

This project contains Terraform code for testing AWS infrastructure deployment with actual cost implications. Warning: Running this example code will incur actual costs in AWS.

Prerequisites

Install AWS CLI

For Ubuntu

curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
sudo apt update && sudo apt install unzip -y
unzip awscliv2.zip
sudo ./aws/install
rm -rf ./aws

For macOS

brew install awscli

Verify installation:

aws --version
Ubuntu

Install Terraform

For Ubuntu

sudo apt update && sudo apt install -y gnupg software-properties-common
wget -O- https://apt.releases.hashicorp.com/gpg | \
gpg --dearmor | \
sudo tee /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 -y

For macOS

brew tap hashicorp/tap
brew install hashicorp/tap/terraform

Verify installation:

terraform --version

Configure AWS Credentials

Set up AWS CLI configuration:

aws configure

You will need to provide:

• AWS Access Key ID
• AWS Secret Access Key
• Default region name (e.g., ap-northeast-2)
• Default output format (json recommended)

Usage

1. Navigate to the desired environment directory

2. Set up your variables file:

cp variables.tf.sample variables.tf

Then edit variables.tf with your specific configuration values

3. Initialize Terraform

terraform init

4. Review the execution plan

terraform plan

5. Apply the infrastructure changes

terraform apply

6. Destroy infrastructure (when needed)

terraform destroy

Important Notes

• Be aware that using these resources may incur actual AWS costs
• Always destroy unused resources to avoid unnecessary charges
• Never commit AWS credentials to version control
• Ensure sensitive files are properly listed in .gitignore
• Review and understand the infrastructure changes before applying them
