Ansible Configuration & DevOps Automation

This repository contains hands-on practice projects and automation experiments using Ansible, focusing on infrastructure automation, server configuration, and DevOps workflows.

The goal of this repository is to demonstrate practical experience with Configuration Management, Infrastructure Automation, and Cloud Operations.

---

Overview

The repository includes multiple Ansible practice modules covering:

• Server configuration automation
• Nginx installation and setup
• Inventory management
• Bash script execution using Ansible
• Infrastructure provisioning experiments
• DevOps automation practices

All examples are tested using Ubuntu servers, AWS EC2 instances, and local WSL environments.

---

Technologies Used

• Ansible
• Linux (Ubuntu)
• AWS EC2
• Bash scripting
• Python
• SSH
• Git & GitHub

Practice Modules

1. Nginx Installation Automation

Automates installation and setup of Nginx on remote Linux servers.

Features:

• Package installation using Ansible
• Service management
• Remote host configuration
• Verification of deployment

Example command:

ansible-playbook -i inventory.yml ansible-nginx/install-nginx.yml

---

2. Running Bash Scripts via Ansible

Demonstrates how Ansible can execute shell scripts remotely.

Examples include:

• Directory creation
• Server setup scripts
• System preparation scripts

Example:

ansible-playbook run-script.yml

---

3. AWS EC2 Automation

This module experiments with Infrastructure as Code concepts using Ansible to interact with AWS.

Features:

• Fetch default VPC
• AWS automation using boto3
• EC2 infrastructure experimentation

Requirements:

• AWS credentials configured
• Python boto3 library installed

---

4. Inventory Management

Demonstrates how to manage servers using Ansible inventory files.

Example inventory:

[webservers]
192.168.1.10
192.168.1.11

[dbservers]
192.168.1.20

---

5. Inventory Validation Tool

A simple Python utility included in the repository to validate server inventory files.

File:

server_inventory_validator.py

Purpose:

• Validate server entries
• Improve inventory structure
• Prevent configuration mistakes

---

Requirements

Install Ansible:

sudo apt update
sudo apt install ansible

Install Python dependencies:

pip install boto3 botocore

---

Running Playbooks

Example command:

ansible-playbook -i inventory.yml playbook.yml

Or with a specific inventory file:

ansible-playbook -i hosts.ini configure-server.yml

---

Learning Goals

This repository focuses on building practical DevOps skills such as:

• Infrastructure as Code
• Configuration Management
• Linux server automation
• Cloud automation with AWS
• DevOps scripting
• Remote server orchestration

---

Security Note

Sensitive files such as:

• private SSH keys
• virtual environments
• environment configuration files

are excluded using .gitignore.

---

Future Improvements

Planned enhancements for this repository:

• Ansible Roles structure
• CI/CD pipeline integration
• Docker container automation
• Terraform + Ansible integration
• Automated infrastructure deployment
