Consumes Terraform State and generates Ansible inventory.
Project description
python-terraform-to-ansible-inventory
This package is for consuming Terraform State, parsing the data, and then generating a functional Ansible inventory which can then be consumed by Ansible.
Ansible Groups
By default all VMs are placed into the Ansible group terraform_vms, however
you can also define additional Ansible groups by leveraging tags on your VM
resources. By default this will currently look for tags.ansible_groups which
can be defined on a resource as below:
NOTE: Currently only limited testing on AWS, Azure, and vSphere resources.
tags {
ansible_groups = "['test', 'cluster']"
}
Installation
Manual
You can manually install this package by executing the following:
python setup.py install
Using pip
You can also install using pip:
pip install TerraformToAnsibleInventory
After installation, you can then use this package from anywhere within your terminal session.
TerraformToAnsibleInventory -t terraform.tfstate.vsphere -i terraform_inventory.yml
Supported Terraform Backends
The following backends are currently supported for consumption.
- local - A local
terraform.tfstatefile present where executing from. - consul - A Consul environment in which Terraform state is stored.
Execution
You can view help to familiarize yourself with the options available for usage by executing:
TerraformToAnsibleInventory --help
...
usage: TerraformToAnsibleInventory [-h] [-b {local,consul}] [-cH CONSULHOST] [-cKV CONSULKV]
[-cP CONSULPORT] [-cS {http,https}] [-i INVENTORY]
[-t TFSTATE]
optional arguments:
-h, --help show this help message and exit
-b {local,consul}, --backend {local,consul}
Define which Terraform backend to parse
-cH CONSULHOST, --consulHost CONSULHOST
Define Consul host when using Consul backend
-cKV CONSULKV, --consulKV CONSULKV
Define Consul KV Pair to query. Ex. Azure/Test
-cP CONSULPORT, --consulPort CONSULPORT
Define Consul host port
-cS {http,https}, --consulScheme {http,https}
Define Consul connection scheme.
-i INVENTORY, --inventory INVENTORY
Ansible inventory
-t TFSTATE, --tfstate TFSTATE
Terraform tftstate file
Using A Local Backend
TerraformToAnsibleInventory -t terraform.tfstate -i terraform_inventory.yml
Using A Consul Backend
TerraformToAnsibleInventory -b consul -cH consul.example.org -cKV Azure/Test -i terraform_inventory.yml

Ansible Terraform Module Usage
When using the terraform Ansible module you have the ability to specify
target which can be a single target or a list of targets. This is particularly
useful when your infrastructure is already provisioned and you would like to
destroy targets. We now add the actual Terraform target as a host variable named
target as seen in the example below:
terraform_vms:
hosts:
acctvm0:
ansible_groups:
- test
- consul_cluster
ansible_host: 10.0.2.4
data_type: azurerm_virtual_machine
inventory_hostname: acctvm0
location: eastus
private_ips:
- 10.0.2.4
public_ips: []
resource_group_name: acctestrg
target: azurerm_virtual_machine.acctvm0
vm_size: Standard_B1s
acctvm1:
ansible_groups:
- test
- consul_cluster
ansible_host: 10.0.2.7
data_type: azurerm_virtual_machine
inventory_hostname: acctvm1
location: eastus
private_ips:
- 10.0.2.7
public_ips: []
resource_group_name: acctestrg
target: azurerm_virtual_machine.acctvm1
vm_size: Standard_B1s
Now if you would like to leverage the Terraform Ansible module to specifically target a resource we can do so as seen below:
playbook.yml:
---
- hosts: localhost
gather_facts: false
become: false
vars:
scripts_dir: ../../scripts
terraform_destroy: false
terraform_destroy_vms: []
terraform_project_path: ../../Terraform
tasks:
- name: Execute Terraform (Provision)
terraform:
project_path: "{{ terraform_project_path }}"
state: present
register: _terraform_execution_provision
when: not terraform_destroy
- name: Execute Terraform (Destroy VMs Only)
terraform:
project_path: "{{ terraform_project_path }}"
state: absent
targets: "{{ terraform_destroy_vms | map('extract', hostvars, ['target']) | join(',') }}"
register: _terraform_execution_destroy
when: >
terraform_destroy_vms != [] and
terraform_destroy
Playbook execution:
First run in check mode to ensure your results are as expected.
ansible-playbook -i Ansible/inventory Ansible/playbooks/terraform.yml --extra-vars "{'terraform_destroy': true,'terraform_destroy_vms': ['acctvm0', 'acctvm1']}" --check
...
TASK [Terraform Results (Destroy VMs Only)] ****************************************************************************************************************************************************************************************************************************************************************************
ok: [localhost] => {
"_terraform_execution_destroy": {
"changed": false,
"command": "/usr/local/bin/terraform destroy -no-color -force -lock=true -target azurerm_virtual_machine.acctvm0 -target azurerm_virtual_machine.acctvm1",
"failed": false,
"outputs": {
},
"state": "absent",
"stderr": "",
"stderr_lines": [],
"stdout": "",
"stdout_lines": []
}
}
Now run normally after validating in check mode.
ansible-playbook -i Ansible/inventory Ansible/playbooks/terraform.yml --extra-vars "{'terraform_destroy': true,'terraform_destroy_vms': ['acctvm0', 'acctvm1']}"
If you would like to destroy all VMs in an Ansible group:
ansible-playbook -i Ansible/inventory Ansible/playbooks/terraform.yml --extra-vars "{'terraform_destroy': true,'terraform_destroy_vms': '{{ groups.consul_cluster }}'}" --check
