Setting Up Terragrunt and Creating a Basic Configuration File

You are a DevOps engineer at a software company that has recently migrated its infrastructure to AWS. As a part of your job, you are responsible for automating the infrastructure deployment process using Terragrunt. Your manager has assigned you a task to set up two EC2 instances in different Availability Zones in order to host a new application that is being tested.

In the files you create in the module directory, you will need to insert the following provided code.

In the main.tf file:

provider "aws" {
  region = "us-east-1"
}

data "aws_vpc" "vpc" {
}

data "aws_subnet" "zone1" {
  filter {
    name = "tag:Name"
    values = ["SubnetA"]
  }
}

data "aws_subnet" "zone2" {
  filter {
    name = "tag:Name"
    values = ["SubnetB"]
  }
}

resource "aws_instance" "ec2_instance_1" {
  subnet_id     = data.aws_subnet.zone1.id
  ami           = var.ami
  instance_type = var.instance_type
  availability_zone = var.az1
}

resource "aws_instance" "ec2_instance_2" {
  subnet_id     = data.aws_subnet.zone2.id
  ami           = var.ami
  instance_type = var.instance_type
  availability_zone = var.az2
}

In the variables.tf file:

variable "instance_type" {
  type = string
}

variable "ami" {
  type = string
}

variable "az1" {
  type = string
}

variable "az2" {
  type = string
}

In the outputs.tf file:

output "public_ip_1" {
  value = aws_instance.ec2_instance_1.public_ip
}

output "public_ip_2" {
  value = aws_instance.ec2_instance_2.public_ip
}

In the files you create in the intro_terragrunt directory, you will need to insert the following provided code.

In the terragrunt.hcl file:

terraform {
  source = "./module///"
}

inputs = {
  instance_type = "t3.micro"
  ami = "ami-06e46074ae430fba6"
  az1 = "us-east-1a"
  az2 = "us-east-1b"
}

To get started, log in to the lab server using the credentials provided:

ssh cloud_user@<Terraform-Controller>
