Create Directory


Create Scripts (inside AWS-PROJ1)

Create aws-connection.tf

provider "aws" {
  access_key = "GET AWS ACCESS KEY"
  secret_key = "GET AWS SECRET KEY"
  region = "us-east-1"

Create aws_instance.tf

resource "aws_instance" "Ubuntu" {
  ami = "ami-08d4ac5b634553e16"
  instance_type = "t2.micro"
  tags = {
    Name = "AWS_Ubuntu_box1"

Create AWS VM

Inside the AWS-PROJ1 directory, type the following:

 Terraform init (output should be live below:

Description automatically generated

Terraform deploy

This will connect to AWS and create the VM AWS_Ubuntu_box1.

Check instances on AWS.
