Deploy & Scale Web App on Kubernetes with RKE2 | Docker vs Kubernetes Explained

🚀 From Docker to Kubernetes – A Practical Demo Using RKE2 In this video, I’ll walk you through deploying a simple web application using Docker, analyze its limitations, and then show how Kubernetes (with RKE2) makes things better with powerful features like self-healing, service discovery, and auto-scaling. 🔧 We'll start by deploying an NGINX container using Docker and see what happens if it crashes. Then we’ll spin up a single-node RKE2 Kubernetes cluster, deploy the same app, expose it using a NodePort service, and scale it effortlessly using Kubernetes deployments. ▬▬▬▬▬▬▬ Timestamps ⏰ ▬▬▬▬▬▬▬ 00:00 - Introduction 00:21 - Deploying Application Using Docker 01:23 - What Happens When Docker Container Crashes 02:24 - Installing RKE2 Single Node Kubernetes Cluster 04:18 - Deploying Application on Kubernetes Using Pods 05:30 - Creating a Deployment in Kubernetes 06:42 - Exposing Application via NodePort Service 08:30 - Scaling Application with Kubernetes Deployment 10:23 - Final Thoughts and Conclusion 🔍 What You’ll Learn Why Docker alone isn't enough in production How to install and configure RKE2 Kubernetes cluster Deploying and exposing apps in Kubernetes How Kubernetes ensures high availability How to scale apps in Kubernetes with a single command 💬 Don’t forget to like, share, and subscribe if you found this helpful.
