  # This EC2 Instance has a public IP and will be accessible directly from the public Internet
  associate_public_ip_address = true

IMO this shouldn't be public. Accessing Dgraph instances should be left to the user using their VPC configuration.

Sure, I'll leave the default to false.

I'd be interested in building a Terraform example for GKE! @hackintoshrao Nice job on your example!

We will close this PR because of its age, however we will be referencing this PR when we start work on CD steps. There is a lot of cleanup currently happening around CI steps, and when we get to CD we will address Terraform, Helm, and Docker.
