Node Microservices with Docker and Kubernetes

This repository contains a set of microservices implemented in Node.js, along with a React client. The microservices include users, tasks, and auth, each of which has a Dockerfile for containerization and Kubernetes configuration for deployment.

Prerequisites

• Node.js (v14+)
• Docker
• Kubernetes (minikube or a Kubernetes cluster)

Getting Started

Running Locally

1. Clone this repository:

   git clone https://github.com/mmmihaeel/node-microservices-docker-kubernetes.git
   cd node-microservices-docker-kubernetes
   cd users-api
   npm install
   cd ../tasks-ap
   npm install
   cd ../auth-api
   npm install
   cd ../client
   npm install
   

2. Run with docker: Start the microservices and client using Docker Compose:

   docker-compose build
   docker-compose up
   

Kubernetes

Apply Kubernetes configurations for each microservice and the client:

kubectl apply -f kubernetes/users-deployment.yaml
kubectl apply -f kubernetes/tasks-deployment.yaml
kubectl apply -f kubernetes/auth-deployment.yaml
kubectl apply -f kubernetes/client-deployment.yaml

Expose the services:

kubectl expose deployment users-deployment --type=LoadBalancer --port=80
kubectl expose deployment tasks-deployment --type=LoadBalancer --port=80
kubectl expose deployment auth-deployment --type=LoadBalancer --port=80
kubectl expose deployment client-deployment --type=LoadBalancer --port=80

Replace LoadBalancer with the appropriate service type for your environment.
