Increment template

[SDBrett]

I'm using a template to provide initial configuration data for my EC2 instances. Part of that configuration is to set a host name using a defined prefix and the counter as a suffix.

The result is all instances are getting the same name 0, as 0 is the first counter index. I use the same variable to set apply tags to the EC2 instance and node in chef and they increment just fine. The only place it doesn't is with the template.

On face value it appears that the template does not not reevaluate the passed variables after they are first set.

The temple resource is configured as

data "template_file" "file_server" {
  template = "${file("userdata.txt")}"
  vars {
    admin_password="${var.administrator_pw}"
    hostname = "${var.file_server.["hostname_prefix"]}-${count.index}"
  }
}

It is applied against the AWS resource as

[user_data = "${data.template_file.file_server.rendered}"]

In the user data file I am referring to the variable with the following line

Rename-Computer -NewName "${hostname}" -Restart -Confirm:$False

I would expect that my servers are named fs-0, fs-1 ..... but the host name is set as fs-0 for every server.

This is on Terraform 0.9.6
