Overview of this book

Although out-of-the-box solutions can help you to get a cluster up and running quickly, running a Kubernetes cluster that is optimized for production workloads is a challenge, especially for users with basic or intermediate knowledge. With detailed coverage of cloud industry standards and best practices for achieving scalability, availability, operational excellence, and cost optimization, this Kubernetes book is a blueprint for managing applications and services in production. You'll discover the most common way to deploy and operate Kubernetes clusters, which is to use a public cloud-managed service from AWS, Azure, or Google Cloud Platform (GCP). This book explores Amazon Elastic Kubernetes Service (Amazon EKS), the AWS-managed version of Kubernetes, for working through practical exercises. As you get to grips with implementation details specific to AWS and EKS, you'll understand the design concepts, implementation best practices, and configuration applicable to other cloud-managed services. Throughout the book, you’ll also discover standard and cloud-agnostic tools, such as Terraform and Ansible, for provisioning and configuring infrastructure. By the end of this book, you’ll be able to leverage Kubernetes to operate and manage your production environments confidently.

Configuring NGINX Ingress Controller

There are three main ways in which to expose Kubernetes services externally: NodePort, load balancers, and Ingress. In this section, we will focus on ingresses, as they fulfill the needs of the majority of the workloads and deployments on Kubernetes clusters.

Ingress exposes TCP/IP L7 services (such as HTTP/HTTPS) and it routes traffic from outside the cluster to services within the cluster. Ingress controls traffic routing through a defined set of rules for each ingress resource and/or a global configuration for all ingress resources.

There are many configurations that an ingress can control, including giving services an external URL, SSL/TLS termination, session validity, and name-based virtual hosting. An ingress controller is the Kubernetes resource that is responsible for fulfilling the ingress.

The most popular and battle-tested ingress is NGINX Ingress Controller. This is an ingress controller for Kubernetes that uses NGINX as a...
