We will initially use CodeBuild projects to help us automate our Terraform development life cycle. Variables are a construct we have not yet used in our configuration. In your Cloud9 IDE, copy your main.tf file from the previous chapter to a new folder called Chapter5. Now, let's create a variable file called tfvars.tf and add the following information:
