Kubernetes for the Absolute Beginners - Hands-On - Demo - Deploying Microservices Application on Kubernetes

The video tutorial guides viewers through setting up a multi-tier application on a Minicube cluster. It covers creating pod definition files for various components like the voting app, result app, Redis, and Postgres. The tutorial explains setting up environment variables for database connectivity and creating services to expose pods. It concludes with testing the application by accessing it through a web browser, ensuring all components work together seamlessly.
