Student Management System with Kind and Kubernetes

A simple Student Management System deployed locally on a Kind-based Kubernetes cluster. This project demonstrates how to combine a backend (Golang + MongoDB), a frontend (Nginx), and Kubernetes manifests to set up a microservice application for local development and testing.

---

Project Features

• 🛠 Backend: Developed in Golang with RESTful APIs.
• 🌐 Frontend: Static files served via Nginx.
• 🐳 Containerized: Dockerized application services.
• 🚀 Kubernetes Deployment: Using Kind to run a local K8s cluster.
• 📦 Database: MongoDB as the backend database.

Before running the project, ensure you have the following tools installed:

• Docker: To build and run the application containers.
• Kind: To set up a local Kubernetes cluster.
• kubectl: To interact with the Kubernetes cluster.

Setup Instructions

1. Set Up Kind Cluster

Create a local Kubernetes cluster using Kind:

kind create cluster --name student-cluster --config kind-cluster-config.yaml

2. Build Docker Images

Build the backend and frontend Docker images:

# Build backend
docker build -t student-backend:latest ./backend

3. Load Docker Images into Kind Cluster

将 Docker 镜像加载到 Kind 集群中：

kind load docker-image student-backend:latest -n student-cluster

4. Install Ingress-NGINX

在 Kind 集群中安装 Ingress-NGINX 控制器：

kubectl apply -f https://kind.sigs.k8s.io/examples/ingress/deploy-ingress-nginx.yaml

验证 Ingress 控制器是否正常运行：

kubectl get pods -n ingress-nginx

---

5. Deploy Application to Kubernetes

Apply the Kubernetes manifests to deploy the services:

kubectl apply -f k8s

---

6. Verify Deployments

检查 Pod 和服务的状态：

kubectl get pods
kubectl get svc

---

Access the Application

一旦所有服务运行正常，通过浏览器访问应用：

• Frontend: http://localhost

• Backend API

  : 测试 API 路径，例如：

  curl http://localhost/api/v1/students

---

Endpoints

Method	Endpoint	Description
GET	/api/v1/students	Get all students
POST	/api/v1/students	Add a new student

---

Clean Up

删除 Kind 集群并释放资源：

kind delete cluster --name student-cluster
