Lab description

You must modify an existing Terraform configuration to deploy a subnet within the Web VPC and provision an EC2 instance inside the subnet. Only t2.micro instances and volumes up to 10GBs are allowed in this lab challenge.

Learning Objectives

:bulb: Create Terraform configuration

Lab date

30-12-2021

Prerequisites

AWS account

EC2 Instance running or Terraform installed locally

Lab steps

1. SSH into the Development EC2 instance (Shell or EC2 Instance Connect).
2. Add to the existing main.tf file to configure the following:
   • Create a subnet resource in Web VPC
   • Create an EC2 instance into the newly created subnet within Web VPC

   That’s how it looks pre:

   

3. That’s want it look afterwards:

provider "aws" {
  version = "2.69"

  region  = "us-west-2" # Oregon
}

data "aws_availability_zones" "available" {
  state = "available"
}

resource "aws_vpc" "web_vpc" {
  cidr_block           = "192.168.100.0/24"
  enable_dns_hostnames = true

  tags = {
    Name = "Web VPC"
  }
}

resource "aws_subnet" "subnet1" {
  vpc_id            = aws_vpc.web_vpc.id
  cidr_block        = cidrsubnet(aws_vpc.web_vpc.cidr_block, 8, 1)
  availability_zone = data.aws_availability_zones.available.names[0]
}

resource "aws_instance" "web" {
  ami = "ami-0528a5175983e7f28"
  instance_type = "t2.micro"
  subnet_id = aws_subnet.subnet1.id
  root_block_device {
    volume_size = "10"
  }
}
