🔰 Kubernetes Basics: Getting Started with Kind

Introduction to Kubernetes with Kind

In this first post of our Kubernetes tutorial series, we’ll get hands-on experience with Kubernetes using Kind (Kubernetes in Docker), a tool that lets you run local Kubernetes clusters using Docker containers as nodes.

What We’ll Cover

Understanding Kubernetes basics
Installing Kind and setting up your first cluster
Key concepts: Pods, Deployments, Services
Your first deployment

Prerequisites

Docker installed on your machine
Basic command-line knowledge
Basic understanding of containers

Installing Kind

# For macOS with Homebrew
brew install kind

# Verify installation
kind version

Creating Your First Cluster

# Create a cluster
kind create cluster --name my-first-cluster

# Verify it's running
kubectl get nodes

Understanding Basic Concepts

What is Kubernetes?

Kubernetes is a container orchestration platform that helps manage containerized applications at scale. Think of it as an automated system administrator that:

Ensures your applications are always running
Scales them when needed
Handles failures automatically
Manages updates and rollbacks

Key Components

Nodes: The machines running your containers
Pods: The smallest deployable units
Deployments: Manages Pod lifecycle
Services: Networking and load balancing

Your First Deployment

Let’s deploy a simple nginx web server:

# nginx-deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-demo
spec:
  replicas: 3
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx:latest
        ports:
        - containerPort: 80

Deploy it with:

kubectl apply -f nginx-deployment.yaml

Verifying Your Deployment

# Check pods
kubectl get pods

# Check deployments
kubectl get deployments

What’s Next?

In the next post, we’ll dive deeper into:

Pod lifecycle management
ConfigMaps and Secrets
Services and Networking
Resource limits and requests
