Terraform VPC Demo

TO-DO : execute the terraform commands to create VPC using vpc.tf and update the command documentation with screenshots

Step 01 : Create a file 00_provider.tf file to include terraform and provider block

terraform {
  required_providers {
    aws = {
    source = "hashicorp/aws"
    version = "~> 5.0"
    }
  }
}

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

    default_tags {
      tags = {
        terraform = "yes"
        project = "terraform-learning"
      }
    }
}

00_provider.tf

Step 02: Create a file 01_vpc.tf to create resource block to create AWS VPC

• Terraform AWS VPC Resource

  resource "aws_vpc" "appvpc" {
      cidr_block = "10.0.0.0/16"
  
      tags = {
        Name = "myapp-vpc"
      }
  }

01_vpc.tf

Step 03: Authenticate to AWS via IAM Credentials

• Terraform AWS Authentication Types

  • Static Credentials - You can use this under provider section, but its NOT A RECOMMENDED Option
  • Environment variables - Recommended Option (example below)
  • IAM credentials stored locally (configuration file $HOME/.aws/credentials)
    • use aws configure to configure the aws credentials

• Example : Using Environment variables via PowerShell
