Terraform Hands-on Project: Crafting a Magical AWS Infrastructure! ✨☁️Day - 66

Hello, fellow cloud architects and Terraform enthusiasts! 🚀 Welcome back to our journey in the mystical world of Terraform.

In our previous escapades, we've covered the basics, configured EC2 instances, and now, brace yourselves as we embark on an even grander adventure. Today, our quest involves creating an entire AWS infrastructure using the enchanting powers of Infrastructure as Code (IaC).

Task at Hand: Weaving the Cloud Realms 🌐

Step 1: Laying the Foundation - VPC Creation

Our journey begins with the creation of a Virtual Private Cloud (VPC). Picture this as the very fabric of our cloud realm with the illustrious CIDR block 10.0.0.0/16.

resource "aws_vpc" "my_vpc" {
  cidr_block = "10.0.0.0/16"
  enable_dns_support = true
  enable_dns_hostnames = true
}

Step 2: Crafting Realms - Subnets Unveiled

Now, let's carve out distinct realms within our VPC - a public subnet (10.0.1.0/24) and a private subnet (10.0.2.0/24).

resource "aws_subnet" "public_subnet" {
  vpc_id     = aws_vpc.my_vpc.id
  cidr_block = "10.0.1.0/24"
  availability_zone = "us-east-1a"
}

resource "aws_subnet" "private_subnet" {
  vpc_id     = aws_vpc.my_vpc.id
  cidr_block = "10.0.2.0/24"
  availability_zone = "us-east-1b"
}

Step 3: Bridging Realms - Internet Gateway and Routes

Connect these realms with an Internet Gateway (IGW) and set up the magical routes.

resource "aws_internet_gateway" "my_igw" {
  vpc_id = aws_vpc.my_vpc.id
}

resource "aws_route_table" "public_route_table" {
  vpc_id = aws_vpc.my_vpc.id
}

resource "aws_route" "internet_route" {
  route_table_id         = aws_route_table.public_route_table.id
  destination_cidr_block = "0.0.0.0/0"
  gateway_id             = aws_internet_gateway.my_igw.id
}

Step 4: Summoning a Mage - EC2 Instance Unleashed

Let's conjure a virtual mage into our public realm! Equipped with AMI ami-0557a15b87f6559cf, adorned in the armor of a t2.micro, and wielding a security group allowing SSH from anywhere.

resource "aws_instance" "web_server" {
  ami           = "ami-0557a15b87f6559cf"
  instance_type = "t2.micro"
  key_name      = "my-key-pair"
  subnet_id     = aws_subnet.public_subnet.id

  security_groups = [
    aws_security_group.allow_ssh.id,
  ]

  user_data = <<-EOF
              #!/bin/bash
              sudo apt-get update
              sudo apt-get install -y apache2
              sudo service apache2 start
              EOF
}

Step 5: Enchantment Unleashed - Elastic IP and a Wondrous Website

Bestow our mage with an Elastic IP for permanence and let it enchant the world with a simple website.

resource "aws_eip" "web_server_eip" {
  instance = aws_instance.web_server.id
}

Step 6: Grand Finale - Witness the Magic Unfold! 🎉

Open your browser and witness the magic as you access the website hosted at the EC2 instance's URL.

There you have it, fellow conjurers of the cloud! A complete AWS infrastructure summoned into existence using Terraform's enchanting IaC techniques. Stay tuned for more magical tasks as we continue our Terraform odyssey. Happy conjuring! 🌟🧙‍♂️ #TerraformMagic #IaCJourney #AWSInfraCrafting
