Welcome to your Terraform learning journey! This repository is designed to take you from zero to hero with real-world Infrastructure as Code (IaC) projects using Terraform. Whether you're just getting started with DevOps or want to solidify your Terraform skills, you're in the right place.
This repo is based on my learning materails from youtube, udemy, online resources and my experiences working with Terraform to deploy infrastructures on the cloud it includes practical examples and guided exercises to help you learn how to:
- Deploy infrastructure using Terraform
- Manage state remotely with HCP Terraform
- Apply best practices using version-controlled workflows
- Build and maintain modular, reusable Terraform code
- Securely manage secrets and variables with Vault integration
Here's a quick overview of what you'll find inside:
| Folder/Module | Description |
|---|---|
variables/ |
Working with input/output variables and locals |
remote-state/ |
Storing and retrieving Terraform state remotely using HCP |
cloud-config/ |
Cloud infrastructure provisioning examples (e.g., AWS) |
vcs-workflow/ |
Setting up VCS-based triggers with GitHub and HCP Terraform |
local-infra/ |
Building local infrastructure for testing and learning |
Before you get started, make sure you have the following:
- ✅ Terraform CLI installed
- ✅ A valid AWS Account
- ✅ An HCP Terraform account
- ✅ A GitHub account (for VCS integration)
- ✅ Basic knowledge of terminal usage
Do NOT hardcode your AWS credentials inside your Terraform files. Instead:
- Store secrets securely using HCP Terraform’s variable UI.
- Use environment variables for local testing:
export AWS_ACCESS_KEY_ID="your-access-key"
export AWS_SECRET_ACCESS_KEY="your-secret-key"🚀 Getting Started
- Fork or clone the repo:
git clone https://github.com/Geoelycom/Terraform.git
cd terraform-learning- Choose a module to start with, e.g., cd variables/
- Initialize the project:
terraform init- Review the plan:
terraform plan- Apply it
terraform apply- Destroy when done:
