steps.md

• Download Terraform CLI from here: https://www.terraform.io/downloads.html
  • Windows x64 version: https://releases.hashicorp.com/terraform/0.12.19/terraform_0.12.19_windows_amd64.zip
• Unzip the terraform.exe to some folder and add it to our PATH or CD to that folder so you can use the exe from that folder
• Create these 3 Terraform files to your working folder:
  • main.tf
  • variables.tf
  • terraform.tfvars
• Run these terraform commands:
  • terraform init
  • terraform plan
  • terraform apply
