## Overview

This repository is a collection of Ansible administration and web-server examples, plus a small PHP login/profile demo. The README’s documented workflow is an operator invoking Ansible against an inventory to run a module on managed hosts. The sampled PHP app separately authenticates users against MySQL, then serves a session-protected profile and logout flow. Other playbooks and deployment configurations are visible in the tree, but their internals were not sampled, so their relationships are left unasserted.

Main entry points: [`full_docker_websrever/website/index.php`](https://github.com/devnotops/ansible/blob/main/full_docker_websrever/website/index.php) (Login and auth), [`full_docker_websrever/website/profile.php`](https://github.com/devnotops/ansible/blob/main/full_docker_websrever/website/profile.php) (Protected profile), [`full_docker_websrever/website/logout.php`](https://github.com/devnotops/ansible/blob/main/full_docker_websrever/website/logout.php) (Session logout), [`hosts.ini`](https://github.com/devnotops/ansible/blob/main/hosts.ini) (Host inventory)
