## Overview

This is an Ansible study repository, not an application: it guides a learner through installing Ansible, defining an inventory, checking connectivity, running ad hoc user/package tasks, and using playbooks for server configuration. Its examples also cover firewall rules and PostgreSQL installation alongside the documented Nginx workflow. The graph treats playbooks and inventories as automation inputs and remote machines as targets; source excerpts were unavailable, so links beyond the README’s stated sequence and filenames are not inferred.

Main entry points: [`Install_app_remote/postgresql/install_potsgresql.yml`](https://github.com/kionovelletto/ansible_study/blob/main/Install_app_remote/postgresql/install_potsgresql.yml) (PostgreSQL install), [`network/simple/3_ping_servers.txt`](https://github.com/kionovelletto/ansible_study/blob/main/network/simple/3_ping_servers.txt) (Connectivity check), [`network/simple/5_playbook_install_nginx_iptables.yaml`](https://github.com/kionovelletto/ansible_study/blob/main/network/simple/5_playbook_install_nginx_iptables.yaml) (Nginx playbook), [`network/simple/2_inventory.cfg`](https://github.com/kionovelletto/ansible_study/blob/main/network/simple/2_inventory.cfg) (Server inventory)
