Tasks to Be Performed:

1. Destroy the previous deployments

2. Create a VPC with the required components using Terraform

3. Deploy an EC2 instance inside the VPC

Assignment 4 Github Repository Link:

GitHub - visaltyagi/Terraform-Assignment-4: Terraform-Assignment-4

Problem (1) Solution: Destroy the previous deployments

Here, we have to destroy the resources created in “Terraform Assignment 3”

Step 1: Go to “Master” & run the “terraform destroy” command to destroy the previous deployments.

terraform destroy

Step 2: Type “yes” to destroy the resources.

Yes

Step 3: Both “hello-vriginia” & “hello-ohio” instances will be terminated successfully.

hello-virginia instance

hello-ohio instance

Problem (2) & (3) Integrated Solution:

2. Create a VPC with the required components using Terraform

3. Deploy an EC2 instance inside the VPC

Step 1: Go to the “Master” instance & create a “main.tf” file for VPC creation.

Use this command: sudo nano main.tf

sudo nano main.tf

Step 2: Paste this script to create the Instance with VPC:

provider "aws" {
     region = "us-east-2"
     access_key = "AKIAQRH4ND34WNGRNWOP"
     secret_key = "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"
}
resource "aws_instance" "assignment-4" {
  ami      = "ami-0b4750268a88e78e0"
  instance_type = "t2.micro"
  subnet_id = aws_subnet.assignment-4-subnet.id
  key_name = "Terraform"
  tags = {
    Name = "assignment-4"
  }
}

resource "aws_vpc" "assignment-4-vpc" {
        cidr_block="10.10.0.0/16"
        tags= {
        Name = "assignment-4-vpc"
        }
}

resource "aws_subnet" "assignment-4-subnet" {
         vpc_id=aws_vpc.assignment-4-vpc.id
         cidr_block="10.10.0.0/18"
         availability_zone="us-east-2a"
         tags = {
         Name = "assignment-4-subnet"
         }

Terraform Script File (main.tf)

Do “CTRL+X” to exit & press “Yes” to save the file. Press “enter” to exit from the file completely.

Step 3: Run the “terraform init” command for initialization.

terraform init

Step 4: Run the “terraform plan” command to plan the infrastructure.,

terraform plan

Resources Created

Step 5: Run the command: “terraform apply” to create the instance with new “VPC” & “subnet”.

terraform apply

Step 5: Type “yes” to create the Instance with the new “VPC” & “Subnet”.

Yes

Step 6: Go to the “Instance” section & “assignment-4” instance will be successfully created with the New “VPC” & its subnet.
