Load Balancer

Load Balancer is a microservice application built with Spring Boot. It provides an endpoint to check the status of the service and is deployed in a Kubernetes cluster. This service interacts with other microservices and is designed to be simple and efficient.

Features

• Status Endpoint: Returns a message including the hostname of the pod serving the request.
• Kubernetes Deployment: Deployed as a Load Balancer service in a Kubernetes cluster.

Getting Started

Prerequisites

• Docker
• Kubernetes (Minikube)
• Maven (JDK 17)

Building the Application

1. Clone the Repository

   git clone https://github.com/mikailakar/LoadBalancer.git
   cd LoadBalancer/order-service

2. Start Minikube

   minikube start

3. Build the Application

   mvn clean package

4. Build the Docker Image

   docker build -t order-service:1.0.0 .

5. Deploy the Application

   kubectl apply -f k8s/order-service.yaml

6. Deploy using Skaffold

   skaffold run

7. Verify the Deployment

   kubectl get pods

8. Create a Tunnel

   minikube tunnel

9. Verify the Service

   kubectl get svc

10. Test the Load Balancer

    Open Postman, create one GET end-point at http://127.0.0.1:8080/status and uncheck Connection(keep-alive). You should see a message indicating the hostname of the pod.
