The video walks through deploying a three‑tier voting application on a local Kubernetes cluster using Minikube, illustrating how each component—frontend, worker, and result services—can be orchestrated as separate pods. After applying the manifests, the voting front‑end is exposed on port 3004 and the result service on port 3005. The presenter copies the generated URLs, accesses the UI, and casts a vote, which is immediately written to a Redis cache and then persisted to a PostgreSQL database via the worker pod. A visual check‑mark confirms the vote was recorded, and the results page shows 100 % for the selected option after a single vote. Switching the selection from dogs to cats updates the percentage in real time, demonstrating the seamless data propagation across pods. The demo validates that a multi‑tier architecture can be reliably deployed, scaled, and monitored on Kubernetes, offering enterprises a reproducible pattern for modernizing legacy monoliths into containerized microservices.
The video explains how Kubernetes services operate when pods are distributed across multiple nodes. When a Service is created, Kubernetes automatically provisions it across every node in the cluster, mapping the target port to a uniform NodePort—illustrated with port 3008—so...
