How would you split Ansible roles for nginx, WordPress, and Joomla if different servers have different service combinations?

To separate Ansible roles for nginx, WordPress, and Joomla when using different combinations of services on various servers, it is important to adhere to the principles of modularity and reusability:

1. Create separate roles:

   • nginx — installation and configuration of the web server.
   • wordpress — installation and configuration of WordPress.
   • joomla — installation and configuration of Joomla.

2. Each role should implement only its own responsibilities without code duplication.

3. In playbooks for specific servers, specify the necessary roles depending on the required set of services. For example:

- hosts: wordpress_servers
  roles:
    - nginx
    - wordpress

- hosts: joomla_servers
  roles:
    - nginx
    - joomla

- hosts: mixed_servers
  roles:
    - nginx
    - wordpress
    - joomla

4. Use variables if needed to configure roles for specific conditions.

This approach ensures flexibility, ease of maintenance, and scalability of the infrastructure.
