Deploy a Microservices App

Project 1: Deploy a Microservices App

What You'll Build

Deploy a 3-service application (frontend, API server, PostgreSQL database) to your local Kubernetes cluster using raw manifests — no Helm. This project ties together everything from Tracks 1–2.

Concepts Applied

• Deployments with proper resource requests/limits
• Services: ClusterIP for internal, NodePort or Ingress for external
• ConfigMaps for application configuration
• Secrets for database credentials
• Ingress for HTTP routing to the frontend and API
• DNS-based service discovery between services
