Practical demo on Kubernetes deployment strategies for developers

Learn the deployment skills every developer should know — without relying on a DevOps person to explain it!

In this demo we walk through three Kubernetes deployment strategies using a real distributed application: a React UI, an Express.js REST API, a Node.js background processor, and MongoDB.

We start by running everything locally with Docker/Podman, then set up a local Kubernetes cluster using Kind, and demonstrate each strategy step by step with live traffic monitoring.

What's covered:
- Running a distributed app locally (API + UI + MongoDB + background processor)
- Docker Compose for integration testing
- Setting up a local Kubernetes cluster with Kind and MetalLB
- Rolling Update — zero-downtime API upgrade from v1 to v2
- Canary deployment — routing 25% of traffic to a new API version
- Blue-Green deployment — instant traffic switch between UI versions with zero downtime

Perfect for developers who want to understand how deployments actually work in production, not just in theory.

Stack: Node.js, React, MongoDB, Docker, Podman, Kubernetes, Kind, MetalLB, kubectl
