Assignment: Deploy a Multi-tier Application on Kubernetes

• Design and create the necessary YAML files to deploy the following components:

  • Frontend Deployment and Service: Deploy a frontend web server (e.g., Nginx) with multiple replicas. Expose the frontend service to access it from outside the cluster.
  • Backend Deployment and Service: Deploy a backend API server (e.g., Node.js, Flask, or any other framework) with multiple replicas. Expose the backend service within the cluster.
  • Database Deployment and Service: Deploy a database (e.g., MySQL or PostgreSQL) with persistent storage for data persistence. Expose the database service within the cluster.

• Configure the appropriate networking between the frontend, backend, and database components.

  • The frontend should be able to communicate with the backend API server.
  • The backend API server should be able to access the database for data storage and retrieval.

• Test the application by accessing the frontend web server from outside the cluster and verifying that it communicates with the backend API server and retrieves data from the database.

• Use appropriate labels and selectors to ensure proper service discovery and communication between components.

• Pay attention to resource requirements and limits to ensure the application runs smoothly within the cluster.

• Consider using Secrets to store sensitive information like database credentials.
