Introduction In the previous article, I introduced the basic concepts of Kubernetes Ingress , and how to use Ingress along with related components ( Nginx Ingress Controller and cert-manager ) to automatically issue TLS certificates when deploying HTTPS applications . In this article, I'll show you how to define rules in Ingress to route traffic to different Services based on your needs. Prepare Docker Image First, you'll need a Docker image to get started. You can either use two different Docker images or follow my next instructions to prepare a Docker image . Here's a code block to create a NodeJS server that displays a title based on an environment variable input: import express from 'express' const port = 3000 const title = 'This is NodeJS Typescript Application' const app = express () app . get ( '/' , ( _ , res ) => { res . send (( process ?. env ?. TITLE ?? title ) + '! Current time is ' + Date . now ()) ...

Introduction This article will guide you through using Nginx Ingress Controller and Cert Manager on Kubernetes (K8s) to automatically issue TLS (Transport Layer Security) certificate . To follow along, you'll need: Basic knowledge of Google Kubernetes Engine for cluster initialization Understanding of K8s Deployment, Service to deploy applications Familiarity with Helm for installing necessary charts. Ingress Ingress is a Kubernetes resource used to manage external access to Services within a cluster . It acts like a traffic router, allowing you to define routing configurations to efficiently manage incoming traffic to Services . Ingress Controller An Ingress Controller is a distinct component from Ingress itself. There are various types of Ingress Controllers , each capable of different deployments. However, their main function is to manage and deploy according to Ingress rules . When requests reach Ingress, the Ingress Controller uses these defined rules to route traffic...
