Can we group resources into ansible groups?

[christian-posta]

I have a terraform script that creates multiple "types" of ec2 instances... so think "web server" "database" type groups.

If i hack the ansible inventory script it would look like this:

[webserver]
node1.example.com
node2.example.com

[database]
node3.example.com

and then my ansible play books would classify tasks based on groups, i.e., install httpd on the "web server" assets only.

Is there a way to generate the hosts using terraform.py such that these groups get created based on some metadata in the terraform resource scripts? ie.. i think maybe role tags do this? https://github.com/CiscoCloud/terraform.py/blob/master/terraform.py#L330

This is how we do it in the mantl project (which uses terraform.py):

Basically set a role tag when creating an instance.
