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.
