Full-Stack Kubernetes Deployment

Overview

This project demonstrates the deployment of a multi-tier full-stack application on Kubernetes. The architecture includes:

• MongoDB Database Tier
• Node.js Backend Tier
• Nginx Web Tier

Key Kubernetes resources used in this project:

• Persistent Volumes & Persistent Volume Claims for MongoDB data storage
• ConfigMaps & Secrets to manage configuration and sensitive data
• Namespaces for resource isolation
• Deployments & Services to manage application components

The project is deployed locally using Minikube to simulate a Kubernetes cluster.

Deployment Steps

1. Create a namespace for the application:

   kubectl create namespace fullstack-app

2. Apply the configuration for environment variables and secrets:

   kubectl apply -f configmap.yml
   kubectl apply -f secret.yml

3. Set up persistent storage for MongoDB:

   kubectl apply -f mongo-pv.yml
   kubectl apply -f mongo-pvc.yml

4. Deploy MongoDB:

   kubectl apply -f mongo-deployment.yml
   kubectl apply -f mongo-service.yml

5. Deploy the Node.js backend:

   kubectl apply -f backend-deployment.yml
   kubectl apply -f backend-service.yml

6. Deploy the Nginx web server:

   kubectl apply -f web-deployment.yml
   kubectl apply -f web-service.yml

Conclusion

Once all components are deployed, the full-stack application will be running within the Kubernetes cluster managed by Minikube. This setup demonstrates a scalable and modular approach to deploying a full-stack application with Kubernetes.
