Terrible

A command line tool for transforming terraform state into ansible inventory files

Terraform is great at deploying infrastructure. This project aims to make using ansible and terraform together easy.

Installing

pip install git+git://github.com/RobotsAndPencils/terrible

Using

Write your terraform config as you usually would

# app.tf
resource "aws_instance" "app-server" {
    ami = "aminumber"
    instance_type = "t2.small"
    key_name = "keyname"
    count = 1
    tags {
        Name = "server"
    }

    connection {
        user = "ubuntu"
        key_file = "key_path"
    }
}

Create a Jinja2 template for your ansible inventory file

# ansible-inventory.j2
# Inventory for provisioning app-server
#
{% for resource in resources %}
{% for key, value in resource.iteritems() -%}
{% if "aws_instance.app-server" in key %}

[app-server]
# you can reference any terraform attribute
# https://www.terraform.io/docs/providers/aws/r/instance.html
{{ value.primary.attributes.public_ip }} ansible_ssh_user=ubuntu

{%- endif %}
{%- endfor %}
{%- endfor %}

Run terraform normally, then use terrible to convert terraform state to ansible inventory

terraform plan
terraform apply

terrible --template-path $PWD \
--template ansible-inventory.j2 \
--tfstate terraform.tfstate \
--inventory-output inventory.ini \

Now you can do normal ansible commands

ansible app-server -m ping --inventory-file=inventory.ini

You may want to set up a virtualenv by running virtualenv .venv; source .venv/bin/activate before you use the make file.

make setup
