## Overview

This repository is a collection of five DevOps demonstrations, not one application. Their shared theme is automating code-to-deployment workflows, with projects focused respectively on Apache web hosting, Docker website deployment, Docker-in-Docker, developer/production deployment, and Terraform-managed Cloud Build/GKE. The README documents the major integrations; sampled source confirms the contact-form email flow in Projects 1 and 4. Details not shown in source are represented only where the README explicitly describes them.

Main entry points: [`DevOps Project-5/main.tf`](https://github.com/abhinav-26/devops-projects/blob/master/DevOps%20Project-5/main.tf) (Terraform configuration), [`DevOps Project-1/Website/sendemail.php`](https://github.com/abhinav-26/devops-projects/blob/master/DevOps%20Project-1/Website/sendemail.php) (Contact handler), [`DevOps Project-4/sendemail.php`](https://github.com/abhinav-26/devops-projects/blob/master/DevOps%20Project-4/sendemail.php) (Contact handler), [`DevOps Project-1/Website/index.html`](https://github.com/abhinav-26/devops-projects/blob/master/DevOps%20Project-1/Website/index.html) (Website)
