In this lecture, we’ll take the theory from Day 52 (Part 1) and bring it to life with a hands-on demo of the Kubernetes Gateway API using NGINX Gateway Fabric (NGF) inside a local KIND cluster. You’ll see how to install NGF via Helm, expose it through a NodePort, and configure Gateways, Listeners, and HTTPRoutes to route traffic to multiple applications (iPhone, Android, Desktop). This will help you clearly understand how the Gateway API’s data plane works in practice — without relying on Ingress annotations or cloud-managed load balancers. 🛠 What You’ll Learn in This Demo: ✅ How to set up a KIND cluster with port mappings for NodePort ✅ Installing Gateway API CRDs and the NGINX Gateway Fabric controller ✅ Deploying sample applications (iPhone, Android, Desktop) ✅ Creating a Gateway with listeners and exposing it via NodePort ✅ Defining HTTPRoutes to route requests to multiple backends ✅ Checking end-to-end connectivity and debugging via proxy pod logs 💡 By the end of this lecture: You’ll have a working mental and practical model of the Gateway API in action, with a functioning demo you can replicate locally. This sets you up to extend into weighted routing, TLS, and cloud-managed environments in future sessions. 🔗 Stay Connected: 👉 LinkedIn: https://linkedin.com/in/varun-joshi-2b516752 👉 GitHub: https://github.com/CloudWithVarJosh 💬 Got questions?
