Quick Setup

Option 1: Kind (Kubernetes in Docker)

# Install kind
curl -Lo ./kind https://kind.sigs.k8s.io/dl/latest/kind-linux-amd64
chmod +x ./kind

# Create cluster
./kind create cluster --name my-cluster

# Verify
kubectl cluster-info
kubectl get nodes

Option 2: Minikube

# Install minikube
curl -LO https://github.com/kubernetes/minikube/releases/latest/download/minikube-linux-amd64
sudo install minikube-linux-amd64 /usr/local/bin/minikube

# Start cluster
minikube start --cpus=4 --memory=8192

# Verify
kubectl get nodes

Option 3: Managed Service

• AWS EKS: Amazon Elastic Kubernetes Service
• Google GKE: Google Kubernetes Engine
• Azure AKS: Azure Kubernetes Service

Your First Deployment

# Create namespace
kubectl create namespace tutorial

# Deploy nginx
kubectl run nginx --image=nginx:latest -n tutorial

# Expose service
kubectl expose pod nginx --port=80 --type=NodePort -n tutorial

# Check service
kubectl get svc -n tutorial

# Access application
# For kind/minikube:
kubectl port-forward -n tutorial svc/nginx 8080:80
# Then visit http://localhost:8080

Core Concepts

Kubernetes Objects

• Pod: Smallest deployable unit
• Service: Network access to pods
• Deployment: Manage pod replicas
• ConfigMap: Configuration storage
• Secret: Sensitive data storage

Key Commands

kubectl get pods
kubectl get services
kubectl get deployments

# Describe resources
kubectl describe pod pod-name
kubectl describe service service-name

# View logs
kubectl logs pod-name
kubectl logs -f pod-name

# Execute in pod
kubectl exec -it pod-name -- /bin/bash
