🧪 Local Development

1. Clone the Repository

  git clone https://github.com/tharikashree/hayroo.git
  cd client
  npm start
  cd server
  npm start

2. Build and Run (Docker Only)

# Build images
docker build -t tharikashree/client ./client
docker build -t tharikashree/server ./server

# Run containers
docker run -p 3000:3000 tharikashree/client
docker run -p 5000:5000 tharikashree/server

Jenkins CI/CD Pipeline

The project includes a declarative Jenkinsfile for automated build, push, and deploy.

Pipeline Stages: 1.Clone GitHub repo

2.Login to Docker Hub

3.Build Docker images

4.Push images to Docker Hub

5.Apply Kubernetes manifests

Ensure Jenkins is configured with:

dockerhub-creds-id → Docker Hub username + access token
kubeconfig-secret → Kube config file (for cluster access)

Kubernetes Deployment

1. Start Minikube (optional)

    minikube start
   

2. Apply K8s Manifests

    kubectl apply -f k8s/
   

3. Access Services

    # Check service URLs
    kubectl get svc
   

If using Minikube

  minikube service client-service
  minikube service server-service

Environment Variables (example) Set up .env files for both client and server:

server/.env

MONGO_URI=mongodb://localhost:27017/hayroo
PORT=5000
JWT_SECRET=your_jwt_secret

client/.env

REACT_APP_API_BASE_URL=http://localhost:5000/api
