Student Dashboard CI/CD Pipeline Implementation

This PR implements a complete CI/CD pipeline for the Student Dashboard application using Docker, Kubernetes, and Jenkins.

🔄 Pipeline Implementation Overview

• Application: Student Dashboard web app (HTML/JS/CSS)
• Container: Docker with nginx:alpine base
• Registry: DockerHub (username: dhruv99269)
• Orchestration: Kubernetes with separate test/prod environments
• CI/CD: Jenkins Pipeline with branch-based deployments
• Branch Strategy:
  • dev → Test environment
  • main → Production environment

🛠️ Key Components

1. Application (student-dashboard/)

• Responsive web dashboard showing student information
• Environment-aware banner (test/production)
• Containerized with nginx

2. Kubernetes Deployments (k8s/)

• deployment-test.yaml: Test environment (1 replica)
• deployment-prod.yaml: Production environment (3 replicas)
• Namespace separation for isolation

3. Jenkins Pipeline (Jenkinsfile)

• Automated build and push to DockerHub
• Environment-specific deployments
• Credential management for DockerHub

✅ Testing Instructions

1. Local Docker Test

cd student-dashboard
docker build -t test .
docker run -p 8080:80 test
# Access at http://localhost:8080

2. Test Environment

kubectl get all -n test
kubectl port-forward svc/student-dashboard-service-test 8080:80 -n test

3. Production Environment

kubectl get all -n production
kubectl port-forward svc/student-dashboard-service-prod 8081:80 -n production

📝 Configuration Updates

Jenkins Requirements

• Pipeline plugin
• Docker Pipeline plugin
• Kubernetes CLI plugin
• Credentials: dockerhub-credentials (configured)

Kubernetes Resources

• Test namespace:

  • 1 replica
  • Memory: 64Mi-128Mi
  • CPU: 100m-200m

• Production namespace:

  • 3 replicas
  • Memory: 128Mi-256Mi
  • CPU: 200m-500m

🚀 Deployment Process

1. Push to dev branch:

   • Triggers test environment deployment
   • Deploys to test namespace
   • Single replica for testing

2. Push to main branch:

   • Triggers production deployment
   • Deploys to production namespace
   • 3 replicas for high availability

📄 Documentation Added

• README.md: Main documentation
• PROJECT_OVERVIEW.md: Architecture and design
• QUICK_START.md: Quick setup guide
• SETUP_CHECKLIST.md: Deployment verification
• HOW_TO_TEST.md: Testing procedures
• JENKINS_CREDENTIALS_SETUP.md: Jenkins configuration

🔍 Testing Done

✅ Docker image builds successfully
✅ Image pushes to DockerHub
✅ Jenkins pipeline executes all stages
✅ Test environment deploys correctly
✅ Production environment deploys correctly
✅ Application functions in both environments
✅ Environment banners show correctly
✅ Kubernetes health checks pass

📊 Resource Considerations

• Separate resource limits for test/prod
• Health checks configured
• Zero-downtime deployments
• Namespace isolation

🔄 Rollback Strategy

# If needed, rollback deployment with:
kubectl rollout undo deployment/student-dashboard-prod -n production

🛡️ Security Considerations

• Namespace isolation
• Resource limits enforced
• DockerHub credentials managed securely
• No sensitive data in images
