Terraform Module to run ansible playbooks.

> [!TIP]
> #### πŸ‘½ Use Atmos with Terraform
> Cloud Posse uses [`atmos`](https://atmos.tools) to easily orchestrate multiple environments using Terraform.

> Works with [Github Actions](https://atmos.tools/integrations/github-actions/), [Atlantis](https://atmos.tools/integrations/atlantis), or [Spacelift](https://atmos.tools/integrations/spacelift).
>
>
> Watch demo of using Atmos with Terraform
>

> Example of running atmos to manage infrastructure from our Quick Start tutorial.

## Usage

### Add special section to the playbook

You must add this section on the top of all playbooks that will be used for provisioning.

This will add a dynamic inventory to target the host that needs provisioning.

e.g. `../ansible/playbooks/playbook.yml`

* Create a runtime inventorty with an ip address of a host
* Wait for target host is ready for ssh connection

```yaml

---
- hosts: localhost
gather_facts: True
check_mode: no
tasks:
- name: Add public ip addresses to an dynamic inventory
add_host:
name: "{{ host }}"
groups: all

- local_action: wait_for port=22 host="{{ host }}" search_regex=OpenSSH delay=10

- hosts: all
gather_facts: False
check_mode: no
become: True
tasks:
- name: Install python 2.7
raw: >
test -e /usr/bin/python ||
(
(test -e /usr/bin/apt-get && (apt-get -y update && apt-get install -y python)) ||
(test -e /usr/bin/yum && (yum makecache fast && yum install -y python))
)
args:
creates: /usr/bin/python
```

### Create an aws instance

```hcl
resource "aws_instance" "web" {
ami = "ami-408c7f28"
instance_type = "t1.micro"
tags {
Name = test1
}
}
```

### Apply the provisioner module to this resource

```hcl
module "ansible_provisioner" {
source = "github.com/cloudposse/tf_ansible"

arguments = ["--user=ubuntu"]
envs = ["host=${aws_instance.web.public_ip}"]
playbook = "../ansible/playbooks/test.yml"
dry_run = false

}
```

> [!IMPORTANT]
> In Cloud Posse's examples, we avoid pinning modules to specific versions to prevent discrepancies between the documentation
> and the latest released versions. However, for your own projects, we strongly advise pinning each module to the exact version
> you're using. This practice ensures the stability of your infrastructure. Additionally, we recommend implementing a systematic
> approach for updating versions to avoid unexpected changes.
