Launch EC2 Instance With Terraform — Steps to provision

What is Terraform?

Terraform is a tool for building, changing, and versioning infrastructure safely and efficiently. Terraform can manage existing and popular service providers as well as custom in-house solutions. Configuration files describe to Terraform the components needed to run a single application or your entire datacenter.

Reference: https://www.terraform.io/intro/index.html

• Connect EC2 Instance with AMI as Linux.
  $ sudo su
  $ ls
• No files can be seen.
• Now copy the terraform file from https://www.terraform.io/downloads.html for Linux.
  $ wget https://releases.hashicorp.com/terraform/0.14.4/terraform_0.14.4_linux_amd64.zip
  $ yum install unzip -y
  $ unzip terraform_0.14.4_linux_amd64.zip
• Set the path for getting terraform cmd available
  $ echo $”export PATH=\$PATH:$(pwd)” >> ~/.bash_profile
  $ source ~/.bash_profile
• Now run the terraform cmd to check weather its working or not?
  $ terraform
  $ mkdir terraform-lab
  $ cd terraform-lab/
  $ vi ec2.tf

provider “aws” {
access_key = “AKIA5W3VEU6TCNAY2FXA”
secret_key = “RNEJ+ZKurXWqBQ8DC18UZVGk+TZveU6fIqlME/Q/”
region = “ap-south-1”
}

resource “aws_instance” “test” {
ami = “ami-0cda377a1b884a1bc”
instance_type = “t2.micro”
key_name = “imran_keypair”
}

• Now initialize the working directory for terraform.
  $ terraform init
• Now Provision the ec2 with this command, you can create (apply) or delete (destroy) the server.
  $ terraform apply
• If it fails check for permission on IAM -> users -> “resource group” provide EC2FullAccess for the user.
• From your terminal/command prompt/ shell, destroy the resources
  $ terraform destroy

That’s it! you installed Terraform and used it to provision an EC2 instance.
