Docker Compose & Kubernetes Demo

This project demonstrates a simple 3-tier application (React Frontend, Node.js API, MySQL Database) capable of running on Docker Compose or Kubernetes (Minikube).

Prerequisites

• Docker
• Minikube
• kubectl

Running on Minikube

1. Start Minikube

   minikube start

2. Build Images in Minikube Engine Important: You must build the images inside Minikube's Docker daemon so that the pods can find them (since we use imagePullPolicy: Never).

   eval $(minikube docker-env)
   docker build -t kub-api ./api
   docker build -t kub-app ./app

   (Alternatively, use minikube image build -t kub-api ./api etc.)

3. Apply Kubernetes Manifests

   kubectl apply -f k8s/

4. Verify Deployment Check that all pods are running:

   kubectl get pods

5. Access the Application To access the Frontend in your browser:

   minikube service app-service

   To access the API directly (optional):

   minikube service api-service

Cleanup

kubectl delete -f k8s/
minikube stop
