Install Terraform & AWS CLI

Source: doonops-curriculum/setup-cli--install-tools.md

Doonops lesson

Goal

Install Terraform and verify AWS CLI — after AWS account lesson if you do cloud labs.

Simple explanation

Two programs on your laptop: Terraform (reads .tf files) and AWS CLI (talks to Amazon with your keys).

Technical view

Terraform 1.9+; AWS CLI v2; credentials via aws configure; provider uses same chain.

Think of it like

Terraform = chef following recipe. AWS CLI = phone line to the supplier (AWS).

Steps

Read simple section
Read analogy + diagram
Copy project files
Do local lab

Deep explanation

Layman words first, then technical detail — read slowly

Install order

AWS setup lesson (if Module 6+ planned) — account + aws configure
Terraform — brew install terraform or official installer
Editor — VS Code + HashiCorp Terraform extension (syntax highlight)

terraform version    → must show 1.9+
aws --version        → must show aws-cli/2.x
aws sts get-caller-identity  → JSON with Account (after configure)

Example (Doonops)

Modern HCL — names are examples, not from any third-party course

Example HCL

# versions.tf
terraform {
  required_version = ">= 1.9.0"
}

Terraform runs on your computer — copy this HCL into a folder, then follow the local lab steps below.

Check

terraform version OK
get-caller-identity OK if AWS labs planned

Project files for this lab

Full implementation folder — copy all files, then run terraform commands

Lab project files (full folder)

Copy every file below into one folder — same as a real repo module. Then run the local lab steps.

Suggested folder: Suggested path: ~/doonops-terraform/03-install-tools/
