🔧 Installation & Setup Guide

Follow these steps to set up your Kubernetes environment and start learning:

1️⃣ Prerequisites

Before starting, ensure you have the following: ✅ Operating System: Linux/macOS (Windows users can use WSL2) ✅ Tools Installed: kubectl, Minikube, Docker ✅ Basic CLI Knowledge: Familiarity with terminal commands

2️⃣ Install Kubernetes CLI (kubectl)

kubectl is the command-line tool to interact with your Kubernetes cluster.

📌 Install kubectl (Linux/macOS)

curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"
chmod +x kubectl
sudo mv kubectl /usr/local/bin/
kubectl version --client

3️⃣ Set Up a Kubernetes Cluster (Using Minikube)

Minikube is a lightweight Kubernetes cluster for local testing.

📌 Install Minikube

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
chmod +x minikube-linux-amd64
sudo mv minikube-linux-amd64 /usr/local/bin/minikube
minikube version

📌 Start Minikube Cluster

minikube start
kubectl get nodes

4️⃣ Deploy Your First App on Kubernetes

Once the cluster is up, let’s deploy a simple Nginx web server.

📌 Create a Deployment

kubectl create deployment nginx --image=nginx

📌 Expose as a Service

kubectl expose deployment nginx --port=80 --type=NodePort

📌 Check Running Pods & Services

kubectl get pods,svc
