Overview of this book

With its broad adoption across various industries, Kubernetes is helping engineers with the orchestration and automation of container deployments on a large scale, making it the leading container orchestration system and the most popular choice for running containerized applications. This Kubernetes book starts with an introduction to Kubernetes and containerization, covering the setup of your local development environment and the roles of the most important Kubernetes components. Along with covering the core concepts necessary to make the most of your infrastructure, this book will also help you get acquainted with the fundamentals of Kubernetes. As you advance, you'll learn how to manage Kubernetes clusters on cloud platforms, such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP), and develop and deploy real-world applications in Kubernetes using practical examples. Additionally, you'll get to grips with managing microservices along with best practices. By the end of this book, you'll be equipped with battle-tested knowledge of advanced Kubernetes topics, such as scheduling of Pods and managing incoming traffic to the cluster, and be ready to work with Kubernetes on cloud platforms.

Chapter 21: Advanced Traffic Routing with Ingress

This last chapter will give an overview of advanced traffic routing in Kubernetes using Ingress resources. In short, Ingress can be used to expose your Pods running behind a Service object to the external world using HTTP and HTTPS routes. We have already discussed ways to expose your application using Service objects directly, especially the LoadBalancer Service. But this approach works fine only in cloud environments where you have cloud-controller-manager running and byconfiguring external load balancers to be used with this type of Service. And what is more, each LoadBalancer Service requires a separate instance of the cloud load balancer, which brings additional costs and maintenance overhead. We are going to introduce Ingress and Ingress Controller, which can be used in any type of environment to provide routing and load-balancing capabilities for your application. You will also learn how to use the nginx web server as Ingress...
