This repository serves as a structured collection of my Ansible learning journey, from core fundamentals to real-world automation scenarios. It contains playbooks, inventory configurations, and practical examples demonstrating Infrastructure as Code (IaC) principles.
The primary goal of this repository is to build a robust foundation in configuration management and server automation, specifically tailored for DevOps and Cloud Engineering roles.
Ansible is a powerful, open-source IT automation tool. It is unique because it is agentless, meaning you do not need to install special software on the servers you want to manage. It connects via standard SSH.
It is widely used in the industry for:
- Configuration Management: Ensuring servers are set up exactly the same way every time.
- Application Deployment: Automating the release of complex, multi-tier applications.
- Server Provisioning: Setting up raw servers with necessary dependencies.
- Task Automation: Replacing manual, repetitive bash scripts with declarative YAML.
This repository is broken down into easily digestible playbooks, each focusing on a core concept of Ansible:
01-playbook-structure: Understanding the basic YAML layout (hosts,tasks,name).02-variables: Declaring, scoping, and accessing data using Jinja2 templating (vars,{{ }}).03-modules: Practical examples of common modules (commandvsshell,package,service,file).04-loops: Executing tasks iteratively using simple lists and dictionaries (loop,item).05-conditions: Controlling task execution flow based on dynamic data (when).06-error-handling: Managing failures gracefully without crashing the playbook (ignore_errors,register).07-filters: Transforming data formats on the fly (e.g., String to List, Dict to JSON).08-idempotency: Demonstrating Ansible's golden rule: achieving the desired state (state: present/absent) safely.
Ensure you have Ansible installed on your control node. Most of these playbooks are configured to run locally for testing purposes (hosts: localhost, connection: local).

Clone the repository:
git clone [https://github.com/chellojuramu/ansible.git](https://github.com/chellojuramu/ansible.git) cd ansible -
Execute a specific playbook:
ansible-playbook <playbook-name>.yml
Example:
ansible-playbook 16-idempotency.yml
The concepts demonstrated in these basic playbooks are currently being utilized to transition a legacy, shell-script-based microservices architecture (RoboShop) into fully automated, declarative Ansible playbooks.
Developed and maintained as part of an ongoing DevOps learning initiative.
