None

Example Playbook
----------------

This is a sample playbook file for deploying the Ansible Galaxy NGINX role in a localhost and installing the open source version of NGINX.

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

This is a sample playbook file for deploying the Ansible Galaxy NGINX role to a dynamic inventory containing the `nginx` tag.

```yaml
---
- hosts: tag_nginx
  remote_user: root
  roles:
    - role: nginxinc.nginx
```

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.

```yaml
- hosts: localhost
  become: true
  roles:
    - role: nginxinc.nginx
  vars:
    nginx_type: plus
    nginx_rest_api_enable: true
    nginx_rest_api_write: true
    nginx_controller_enable: true
    nginx_controller_api_key: <API_KEY_HERE>
    nginx_controller_api_endpoint: https://<FQDN>/1.4
```

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`.
