# 1) Install Terraform & Configure AWS (15 min)

We’ll install Terraform and set up your AWS credentials on **Ubuntu 24.04**.

### A. Install Terraform

```bash
sudo apt-get update
```
Updates the local package index so your system knows about the latest software versions.

```bash
sudo apt-get install -y gnupg software-properties-common wget
```
Installs essential tools:
- **gnupg** → handles security keys  
- **software-properties-common** → helps manage repositories  
- **wget** → used to download files

```bash
wget -O- https://apt.releases.hashicorp.com/gpg | gpg --dearmor | sudo tee /usr/share/keyrings/hashicorp.gpg
```
Downloads and stores HashiCorp’s official GPG key for verifying Terraform packages.

```bash
echo "deb [signed-by=/usr/share/keyrings/hashicorp.gpg] https://apt.releases.hashicorp.com $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/hashicorp.list
```
Adds the HashiCorp package repository to your system so Terraform can be installed and updated.

```bash
sudo apt update && sudo apt install -y terraform
```
Refreshes package list again and installs the latest Terraform release.

```bash
terraform -v
```
Verifies Terraform is installed by printing its version.


### B. Install AWS CLI v2

```bash
sudo apt-get install -y unzip
```
Installs **unzip**, required to extract the AWS CLI package.

```bash
curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
```
Downloads the AWS CLI v2 installer.

```bash
unzip awscliv2.zip
```
Extracts the AWS CLI installer files.

```bash
sudo ./aws/install
```
Runs the AWS CLI installer to make it available system-wide.

```bash
aws --version
```
Checks that AWS CLI is installed successfully.


### C. Configure AWS credentials

```bash
aws configure
```
Starts interactive setup for AWS CLI. Enter:

- **AWS Access Key ID**: (from your IAM user)  
- **AWS Secret Access Key**: (from your IAM user)  
- **Default region name**: `ap-south-1` (Mumbai, for this lab)  
- **Default output format**: `json`  

This creates config files (~/.aws/config and ~/.aws/credentials) so both AWS CLI and Terraform can connect securely to AWS.
