Kubernetes Services : ClusterIP vs NodePort vs LoadBalancer | Tutorial #6

Description

Kubernetes Services explained with a simple Ola/Uber analogy — the easiest way to understand ClusterIP, NodePort, and LoadBalancer. If you've ever wondered how to access your application after deploying Pods in Kubernetes, this video is for you. We'll break down why Pod IPs are unreliable, how Services solve this problem, and demo all 3 service types in action — so you'll never connect to a Pod IP again. This is Part 6 of the Kubernetes Beginner Series — designed for DevOps engineers, cloud certification aspirants, and developers learning Kubernetes from scratch. 🎯 What You'll Learn: ✅ Why Pod IPs are unstable and break your apps ✅ What a Kubernetes Service actually does (with a real-world analogy) ✅ ClusterIP — for internal Pod-to-Pod communication ✅ NodePort — for external access during testing ✅ LoadBalancer — for production deployments on cloud ✅ Hands-on demo: All 3 service types with live kubectl commands ✅ How Services automatically track changing Pod IPs 📋 Prerequisites — Watch the Series in Order: ▶️ Part 1: Kubernetes Introduction → https://youtu.be/wuiN9jq6RNI ▶️ Part 2: Kubernetes Architecture → https://youtu.be/rV1OAS9ao94 ▶️ Part 3: Kubernetes Installation → Windows - https://youtu.be/c8EZf7_KwQ8 Mac - https://youtu.be/t6U4AjFEzlE Ubuntu - https://youtu.be/gtFYD-slXIk ▶️ Part 4: Pods & kubectl Commands → https://youtu.be/oWBXz87VNSk ▶️ Part 5: Kubernetes Deployments → https://youtu.be/puCJaUpOOiY ⌨️ Commands Used in This Video: - kubectl get pods -o wide - kubectl apply -f clusterip-service.yaml - kubectl apply -f nodeport-service.yaml - kubectl apply -f loadbalancer-service.yaml - kubectl get svc - kubectl get endpoints 🔔 Subscribe for the complete Kubernetes Beginner Series. 💬 Drop your questions in the comments — I read and reply to every one! #kubernetes #devops #kubernetestutorial #k8s #cloudnative Timestamp : 0:00 Intro — How Do You Access Your App? 0:28 The Problem: Pod IPs Keep Changing 1:57 What is a Kubernetes Service? 2:18 The Ola/Uber Analogy 3:50 Types of Kubernetes Services (ClusterIP/NodePort/LoadBalancer) 5:53 Demo Setup: Checking Our Pods 7:12 Demo: ClusterIP in Action 15:09 Demo: NodePort in Action 19:14 Demo: LoadBalancer in Action 21:19 Demo : LoadBalancer on Azure Kubernetes Service 22:25 Summary & Key Takeaway 23:14 Next Steps
