🚀 DevOps "Nothing to Everything" Hub

Managed & Developed by: Saurabh Singh Rajput

Welcome to the ultimate DevOps learning repository! This project is designed to take you from a basic software application to a fully automated, containerized, and orchestrated cloud-native solution.

🛠️ Project Overview

This repository uses a .NET Task Manager as the core application to demonstrate the complete DevOps lifecycle. Whether you are a beginner or looking to professionalize your workflow, this project covers it all.

🗺️ DevOps Roadmap: Nothing to Everything

🟢 Level 1: The Foundation (Development)

• Source Code: Located in src/TaskManager. A functional C# console app.
• Best Practices: Standardized folder structure, clean code, and separation of concerns.
• Action: Try running the app locally using dotnet run.

🟡 Level 2: Containerization (Docker)

• Dockerfile: Multi-stage builds to optimize image size and security.
• Docker Compose: Orchestrate the app with local storage persistence.
• Location: infrastructure/docker/
• Goal: Package the app so it runs anywhere identically.

🟠 Level 3: Orchestration (Kubernetes)

• Deployment: Scaling your app to handle traffic.
• Persistence: Using PVC (Persistent Volume Claims) for data storage.
• Service: Exposing your application to the network.
• Location: infrastructure/kubernetes/
• Goal: Manage containers at scale with self-healing capabilities.

🔴 Level 4: Infrastructure as Code (Terraform)

• Provisioning: Automatically create cloud resources (Resource Groups, ACR, AKS).
• Cloud Provider: Focused on Azure (easily adaptable to AWS/GCP).
• Location: infrastructure/terraform/
• Goal: Treat your infrastructure like code—versionable and repeatable.

🔵 Level 5: Automation (CI/CD)

• GitHub Actions: Automate the entire process.
• Pipeline: Every push builds the code, runs tests, and creates Docker images.
• Location: .github/workflows/
• Goal: Faster delivery with high reliability and zero manual intervention.

🚀 How to Learn from This Project

1. Clone the Repo: Start by exploring the src/ folder.
2. Build the Container: Move to infrastructure/docker and run docker-compose up --build.
3. Explore Orchestration: Look at infrastructure/kubernetes to see how a production-grade deployment is defined.
4. Provision Cloud: Use the infrastructure/terraform files to see how to script a cloud environment.
5. Watch the Magic: Check the "Actions" tab in GitHub to see the CI/CD pipeline in action.
