+### Minikube Setup
+
+Install and run [Minikube](https://kubernetes.io/docs/setup/minikube/):
+
+1. Install a  [Hypervisor](https://kubernetes.io/docs/tasks/tools/install-minikube/#install-a-hypervisor) (like [VirtualBox](https://www.virtualbox.org/wiki/Downloads) or [HyperKit](https://github.com/moby/hyperkit)) to manage virtual machines
+1. Install and Set Up [kubectl](https://kubernetes.io/docs/tasks/tools/install-kubectl/) to deploy and manage apps on Kubernetes
+1. Install [Minikube](https://github.com/kubernetes/minikube/releases)
+
+Start the cluster:
+
+```sh
+$ minikube start --memory 8192 --cpus 4
+$ minikube dashboard
+```
+
+Build the Docker image:
+
+```sh
+$ eval $(minikube docker-env)
+$ docker build -t spark-hadoop:2.2.1 .
+```
+
+Create the deployments and services:
+
+```sh
+$ kubectl create -f ./kubernetes/spark-master-deployment.yaml
+$ kubectl create -f ./kubernetes/spark-master-service.yaml
+$ kubectl create -f ./kubernetes/spark-worker-deployment.yaml
+$ minikube addons enable ingress
+$ kubectl apply -f ./kubernetes/minikube-ingress.yaml
+```
+
+Add an entry to /etc/hosts:
+
+```sh
