🎓 Capstone Project: DevOps Case Study (To be Delivered by Students)

📌 Project Title:

E-Commerce Web Application Deployment Using DevOps

📖 Case Study Scenario:

A startup ShopEasy wants to build and deploy its Java-based e-commerce web application with the following requirements:

• The application must go through a complete SDLC pipeline (development → testing → deployment).
• The company wants automated builds, containerization, CI/CD pipelines, configuration management, and monitoring.
• Your job is to design, implement, and document the end-to-end DevOps pipeline using the tools learned in the course.

---

🛠️ Problem Statement:

Students must design and implement a CI/CD pipeline for ShopEasy with the following deliverables:

---

📑 Tasks & Requirements (Point-Wise):

1. Source Code Management (Git & GitHub 🐙)

• Create a GitHub repository for ShopEasy.
• Push the Java e-commerce app source code into the repository.
• Create branches (dev, test, prod) and demonstrate branching strategies.
• Use Git workflow commands: commit, merge, rebase, squash, cherry-pick.
• Protect the main branch with PR approvals.

---

2. Build Automation (Maven ☕)

• Configure Maven to build the Java project.
• Generate the .war or .jar file.
• Define custom Maven profiles for dev, test, and prod.

---

3. Containerization (Docker 🐳)

• Create a Dockerfile for the application.
• Build custom Docker images from the Maven build.
• Run the app inside a Docker container.
• Push the image to Docker Hub / private registry.

---

4. Orchestration (Kubernetes ☸️)

• Deploy the Dockerized app to a Kubernetes cluster.

• Create Kubernetes objects:

  • Deployment
  • Service (NodePort / LoadBalancer)
  • ConfigMaps & Secrets for environment variables
  • Persistent Volume for data storage

• Enable Horizontal Pod Autoscaling (HPA).

• Install Prometheus & Grafana for monitoring.

---

5. Configuration Management (Ansible 📦)

• Write Ansible Playbooks to:

  • Install Docker & Kubernetes on nodes.
  • Configure cluster nodes with required packages.
  • Automate deployment of the app onto Kubernetes.

---

6. CI/CD Pipeline (Jenkins ⚙️)

• Set up a Jenkins pipeline (using Jenkinsfile).

• Stages should include:

  1. Checkout code from GitHub
  2. Build using Maven
  3. Run Unit Tests
  4. Build Docker Image
  5. Push Image to registry
  6. Deploy to Kubernetes

• Use Webhooks for auto-trigger from GitHub commits.

• Use Blue Ocean for visualization.

---

7. Test Automation (Selenium 🧪)

• Write Selenium test scripts to:

  • Verify login, signup, add-to-cart, and checkout flows.

• Integrate Selenium tests into the Jenkins pipeline (run after build stage).

---

8. Monitoring & Logging (Bonus 🎯)

• Configure Prometheus for metrics (CPU, memory, pod health).
• Configure Grafana dashboards for visualization.
• Use Kubernetes logs (kubectl logs) to debug issues.

---

Final Deliverables

Students must deliver the following:

1. GitHub Repository with source code + branching strategy.
2. Maven Build setup.
3. Docker Image pushed to registry.
4. Kubernetes Deployment YAMLs.
5. Ansible Playbooks for automation.
6. Jenkins CI/CD Pipeline with Jenkinsfile.
7. Selenium Test Reports.
8. Monitoring Dashboard (Prometheus + Grafana screenshots).
9. Case Study Report (Documentation) explaining the entire pipeline.
