How to Install Terraform and Create Your First Resource
Published on: October 30, 2023 | Author: DevOps Engineering Team
Welcome to Part 2 of our Terraform Mastery Series! In this hands-on guide, you'll install Terraform on your machine and write your first configuration to create a real cloud resource. By the end of this tutorial, you'll have executed the complete Terraform workflow and understand the fundamental concepts of Infrastructure as Code.
What You'll Learn
Prerequisites: What You Need Before Starting
Before we dive into installation, let's make sure you have everything you need:
Required Tools
- A supported operating system: Windows, macOS, or Linux
- Command-line access: Terminal, Command Prompt, or PowerShell
- Cloud provider account (optional but recommended): AWS, Azure, or Google Cloud
- Text editor: VS Code, Sublime Text, or any code editor
Cloud Account Setup
For this tutorial, we'll use AWS as our cloud provider. If you don't have an AWS account, you can create a free tier account. Don't worry - we'll create resources that fall within the free tier limits.
Installing Terraform on Your System
Terraform is a single binary, making installation straightforward. Choose your operating system below for specific instructions:
Windows Installation
Method 1: Chocolatey (Recommended)
Method 2: Manual Installation
- Download the Windows AMD64 package from terraform.io
- Unzip the package to a directory (e.g., C:\terraform)
- Add the directory to your system PATH
macOS Installation
Method 1: Homebrew (Recommended)
Method 2: Manual Installation
- Download the macOS AMD64 package from terraform.io
- Unzip the package
- Move the binary to /usr/local/bin
Linux Installation
Method 1: Using the package manager
Method 2: Manual Installation
- Download the Linux AMD64 package from terraform.io
- Unzip the package
- Move the binary to /usr/local/bin
Package Manager Options
Terraform is available through various package managers:
- Windows: Chocolatey, Windows Package Manager
- macOS: Homebrew, MacPorts
- Linux: apt (Ubuntu/Debian), yum (CentOS/RHEL), dnf (Fedora)
Using package managers ensures you can easily update Terraform later.
Verifying Your Installation
After installation, verify that Terraform is working correctly:
You should see output similar to:
Installation Successful!
If you see the version information, congratulations! Terraform is correctly installed on your system. If you encounter any issues, double-check that the Terraform binary is in your system PATH.
Setting Up Your First Terraform Project
Now let's create your first Terraform project. Follow these steps:
Create Project Directory
Create a new directory for your Terraform project and navigate into it:
Set Up Cloud Credentials
Configure your cloud provider credentials. For AWS, you can use the AWS CLI:
Or set environment variables:
Writing Your First Configuration
Create a file called main.tf in your project directory with the following content:
# Configure the AWS Provider
terraform {
required_providers {
aws = {
source = "hashicorp/aws"
version = "~> 5.0"
}
}
}
# Configure the AWS Provider
provider "aws" {
region = "us-east-1"
}
# Create a S3 bucket
resource "aws_s3_bucket" "my_first_bucket" {
bucket = "my-unique-bucket-name-12345" # Change this to a unique name
tags = {
Name = "My First Bucket"
Environment = "Dev"
Project = "Terraform Learning"
}
}
# Output the bucket name
output "bucket_name" {
value = aws_s3_bucket.my_first_bucket.bucket
}Understanding the Configuration
- Terraform Block: Specifies required providers and their versions
- Provider Block: Configures the AWS provider with your region
- Resource Block: Defines the S3 bucket to create
- Output Block: Displays information after deployment
Important: Unique Bucket Name
S3 bucket names must be globally unique. Change my-unique-bucket-name-12345 to something unique, like adding your name or random numbers.
Running the Complete Terraform Workflow
Now let's execute the three core Terraform commands:
terraform init
Initialize your Terraform working directory:
This command downloads the required provider plugins and sets up the backend.
terraform plan
Create an execution plan:
Terraform will show you what resources will be created. Review the plan carefully!
terraform apply
Apply the changes to create your infrastructure:
Terraform will ask for confirmation. Type yes to proceed. Watch as your S3 bucket is created!
Congratulations!
You've successfully created your first infrastructure with Terraform! You should see output showing your bucket name and a message confirming the creation.
Cleaning Up Resources
Since we're just practicing, let's clean up the resources we created to avoid unnecessary charges:
Terraform will show you what resources will be destroyed and ask for confirmation. Type yes to proceed.
Why Destroy?
Running terraform destroy removes all resources managed by your Terraform configuration. This is great for:
- Avoiding cloud costs for demo resources
- Testing your cleanup process
- Ensuring you can tear down environments completely
What's Next in Your Journey
You've taken your first major step in mastering Terraform! Here's what you've accomplished:
Installation Complete
You've successfully installed Terraform on your local machine.
First Configuration
You've written your first Terraform configuration file.
Full Workflow Executed
You've run the complete init → plan → apply → destroy workflow.
Real Infrastructure
You've created and destroyed actual cloud resources.
In the next part of our series, we'll dive deeper into the Terraform Configuration Language (HCL), where you'll learn about variables, data sources, and more complex resource configurations.
Key Takeaways
- Terraform installation is straightforward across all major operating systems
- The core workflow is
init→plan→apply→destroy - Always run
terraform planbefore apply to review changes - Clean up resources with
terraform destroywhen you're done experimenting - Terraform configurations use the HashiCorp Configuration Language (HCL)
