Introduction
As a Linux engineer diving into infrastructure-as-code, I built a production-ready AWS VPC module using Terraform - with some Linux command-line wisdom sprinkled in. Here's how you can leverage both worlds to create maintainable cloud infrastructure.`

Lab 3: Git Cheat Sheet

Lab 1: Authoring the VPC Module (Linux Style)

1. Core Infrastructure (With Linux Parallels)

main.tf - The "Infrastructure Blueprint"

Linux Analogy:

Like building /etc/network/interfaces using variables from envvars
for_each ≈ for i in {1..3}; do ip addr add ...; done

2. Linux-Inspired Validation

variables.tf - The "Configuration Panel"

Linux Parallels:

validation ≈ [[ "$CIDR" =~ ^[0-9./]+$ ]] || exit 1
type constraints ≈ declare -i PORT=80 (type enforcement)

3. Linux Comparison Focus

outputs.tf - The "API Endpoints"

Why This Matters:

Reusability: Other modules/Terraform workspaces can consume these
Debugging: Quickly get IDs without AWS console (like ip a for networking)
Automation: Feed outputs into scripts (similar to $(hostname) in bash)

Key Takeaways for Linux Engineers

main.tf = Your config_file (e.g., sshd_config)
variables.tf = ENV vars + input validation (set -u)
outputs.tf = stdout for other processes (| grep)

Pro Tip: Add this to your ~/.bashrc for quick outputs:

Lab 2: Git Integration (Terminal Workflow)

1. Initialize Git Repo
