Welcome back to your Terraform journey.

In the previous tasks, you have learned about the basics of Terraform, its configuration file, and creating an EC2 instance using Terraform. Today, we will explore more about Terraform and create multiple resources.

1.Create a VPC (Virtual Private Cloud) with CIDR block 10.0.0.0/16

  • Create a public subnet with CIDR block 10.0.1.0/24 in the above VPC.

    • Create a private subnet with CIDR block 10.0.2.0/24 in the above VPC.

      • Create an Internet Gateway (IGW) and attach it to the VPC.

  • Create a route table for the public subnet and associate it with the public subnet. This route table should have a route to the Internet Gateway.

  • Create a route table for the public subnet and associate it with the public subnet. This route table should have a route to the Internet Gateway.

code for above tasks:

        terraform {
         required_providers {
                aws = {
                source  = "hashicorp/aws"
