This is a sample playbook file for deploying the Ansible Galaxy NGINX role in a localhost and installing NGINX Plus.

```yaml
---
- hosts: localhost
  become: true
  roles:
    - role: nginxinc.nginx
  vars:
    nginx_type: plus
```

This is a sample playbook file for deploying the Ansible Galaxy NGINX role in a localhost to install NGINX Plus and the NGINX Controller agent. Commented out
are sample variables to install the NGINX Controller agent from your NGINX Controller instance instead of the NGINX repository.

```yaml
- hosts: localhost
  become: true
  roles:
    - role: nginxinc.nginx
  vars:
    nginx_type: plus
    nginx_rest_api_enable: true
    nginx_rest_api_port: 80
    nginx_rest_api_write: true
    nginx_controller_enable: true
    nginx_controller_source: repository
    nginx_controller_api_key: <API_KEY_HERE>
    nginx_controller_endpoint: <FQDN> # e.g. controller.nginx.com
    # nginx_type: plus
    # nginx_rest_api_enable: true
    # nginx_rest_api_port: 80
    # nginx_rest_api_write: true
    # nginx_controller_enable: true
    # nginx_controller_source: instance
    # nginx_controller_endpoint: controller.nginx.com
    # nginx_controller_user_email: john_doe@nginx.com
    # nginx_controller_password: password
```

This is a sample playbook file for deploying the Ansible Galaxy NGINX role in a localhost to install NGINX Unit and the PHP/Perl NGINX Unit language modules.

```yaml
---
- hosts: localhost
  become: true
  roles:
    - role: nginxinc.nginx
  vars:
    nginx_enable: false
    nginx_unit_enable: true
    nginx_unit_modules:
      - unit-php
      - unit-perl
```

To run any of the above sample playbooks create a `setup-nginx.yml` file and paste the contents. Executing the Ansible Playbook is then as simple as executing `ansible-playbook setup-nginx.yml`.

Alternatively, you can also clone this repository instead of installing it from Ansible Galaxy. If you decide to do so, replace the role variable in the previous sample playbooks from `nginxinc.nginx` to `ansible-role-nginx`.
