DevOps Project: Java Microservices Deployment with CI/CD & Kubernetes Objective: Candidates will develop, containerize, and deploy a Java Spring Boot Microservices Application using open-source DevOps tools. This project focuses on building microservices, automating deployment, monitoring, and managing logs.
Project Scope (2 Weeks) Tech Stack Backend: Java (Spring Boot), PostgreSQL CI/CD: Jenkins, GitHub Actions Containerization: Docker Orchestration: Kubernetes (Minikube/K3s) Infrastructure as Code: Terraform Monitoring: Prometheus, Grafana Logging: ELK Stack (Elasticsearch, Logstash, Kibana)
Week 1: Develop Microservices & CI/CD Task 1: Develop Java Spring Boot Microservices Create 2 microservices: User Service: Manages user accounts (CRUD). Order Service: Handles order processing. Use Spring Boot, Spring Data JPA, and PostgreSQL. Implement RESTful APIs with Swagger documentation. Secure APIs using Spring Security + JWT authentication. Write unit and integration tests (JUnit + Mockito).
Task 2: Containerization with Docker Write Dockerfiles for each microservice. Create docker-compose.yml to run services locally.
Task 3: CI/CD Pipeline (Jenkins + GitHub Actions) Automate the following using Jenkins and GitHub Actions: Build & Test: Run tests on every push. Containerization: Build and push Docker images to Docker Hub. Deployment: Deploy services to Kubernetes using Helm.
Week 2: Deployment & Monitoring Task 4: Infrastructure as Code (Terraform) Use Terraform to provision a VM on AWS/Azure/GCP. Install Kubernetes (K3s/Minikube) on the VM.
Task 5: Deploy Microservices on Kubernetes Write Kubernetes manifests (deployment.yaml, service.yaml) for each service. Set up PostgreSQL as a StatefulSet in Kubernetes. Implement Service Discovery using Kubernetes Services. Configure Horizontal Pod Autoscaling (HPA).
Task 6: Monitoring & Logging Deploy Prometheus + Grafana to monitor API performance. Set up ELK stack (Elasticsearch, Logstash, Kibana) for centralized logging.
Deliverables ✅ GitHub Repository with microservices source code ✅ CI/CD pipeline scripts (Jenkins file + GitHub Actions YAML) ✅ Docker & Kubernetes manifests ✅ Terraform scripts ✅ Monitoring dashboards (screenshots or live link)
Stretch Goals (Bonus) 🚀 Implement API Gateway (Spring Cloud Gateway) for routing. 🚀 Set up Circuit Breaker (Resilience4j/Hystrix) for fault tolerance. 🚀 Use Kafka/RabbitMQ for inter-service communication.
Outcome This project ensures candidates understand microservices, containerization, automation, and monitoring—key DevOps skills!
