My name is Tennie, and I began my DevOps journey a few months ago. I am passionate about continuous learning, and I recently joined the Terraform 30-Day Challenge to deepen my understanding and sharpen my skills in infrastructure automation. My goal for this challenge is to become proficient in Terraform, master its concepts and applications, and ultimately achieve certification. For the next 30 days, I will be updating my progress as I take on this exciting learning journey!
Day 3
In this article i will be explaining Deploying Your First Server with Terraform as a beginner
Terraform is a powerful Infrastructure as Code (IaC) tool that allows you to define and provision your infrastructure using declarative configuration files. This guide will walk you through the steps to deploy your first server using Terraform. By the end of this article, you’ll have a basic understanding of how Terraform works and a running server.
Prerequisites
Before you begin, ensure you have the following:
Terraform Installed: Download and install Terraform from Terraform’s official website.
Cloud Provider Account: Create an account with your preferred cloud provider (e.g., AWS
Access Credentials: Set up access credentials for your cloud provider.
Code Editor: Use a code editor like Visual Studio Code.
Step 1: Initialize Your Terraform Project
Create a Project Directory:
mkdir terraform-server-deploy && cd terraform-server-deploy
Write Your First Configuration File:
Create a file named main.tf and open it in your editor. Add the following:
provider "aws" {
region = "us-west-2"
}
resource "aws_instance" "example" {
ami = "ami-0c55b159cbfafe1f0"
instance_type = "t2.micro"
tags = {
Name = "TerraformExampleServer"
}
}
Replace the ami value with an appropriate AMI ID for your region.
Initialize the Directory:
Run the following command to initialize your project:
terraform init
This downloads the necessary provider plugins.
Step 2: Preview and Apply the Configuration
Preview Changes:
Run terraform plan to see what Terraform will create:
terraform plan
Apply the Configuration:
Use the following command to create the server:
terraform apply
Review the proposed changes and type yes to confirm.
Step 3: Verify the Server
Once the terraform apply command completes, you’ll see output with information about the resources created. Use your cloud provider’s console to confirm the instance is running.
Step 4: Clean Up Resources
To avoid unnecessary charges, destroy the resources when you’re done:
terraform destroy
Type yes to confirm the destruction of resources.
