Terraform — Prerequisites

What You Need Before Starting Terraform

Terraform provisions real cloud infrastructure. A few foundations will save you hours of confusion.

Required

1. A Cloud Provider Account

Terraform needs somewhere to create resources. Recommended starting points (all free):

Start with whichever cloud you're learning. AWS is the most common for DevOps roles.

2. Basic Cloud Concepts

You should understand what these are (not how to configure them — Terraform handles that):

If these are unfamiliar, spend 2-3 hours in the cloud provider's "getting started" docs or this site's Cloud section first.

3. Basic Command Line

# You need these:
cd, ls, mkdir, cat      # Navigate and create files
nano or vim             # Edit files
export VAR=value        # Set environment variables

4. Basic Understanding of YAML/JSON (Helpful)

Terraform uses HCL (HashiCorp Configuration Language), which is similar. Understanding key-value pairs and nested structure helps.

Nice to Have

Git Basics

Terraform code should always be in version control. git add, git commit, git push is enough.

Linux Basics

You'll run Terraform from a terminal. The more comfortable you are with Linux, the smoother this goes.

Networking Basics

Terraform often creates VPCs, subnets, and security groups. Understanding CIDR notation (10.0.0.0/24) and inbound/outbound rules helps.
