• create the files described below

• please note, you will need the private key to access it.

• run terraform, and answer the following questions: 1. shat changes to the code you needed to perform? 2. how built the state file? 3. run terraform graph, observe it, how it built? why?

     terraform init
     terraform plan -var-file='terraform.tfvars' 
     terraform apply -var-file='terraform.tfvars'
  

terraform.tfvars

aws_access_key = "<insert access key here>"
aws_secret_key = "<insert secret key here>"
private_key_path = "<path to private key>"

terraform file: main.tf
