Kubernetes in Production Best Practices

By: Aly Saleh, Murat Karslioglu

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.

Chapter 5: Configuring and Enhancing Kubernetes Networking Services

In the previous chapter, you learned how to develop a configuration management solution for Kubernetes with Ansible. After completing that solution, you are now ready to build the upper layer of the Kubernetes cluster, and deploy the networking services and add-ons on top of it.

In this chapter, we will learn about enhancing and fine-tuning the essential networking services and add-ons, such as CoreDNS, ExternalDNS, and Ingress Controller. We will not dig into the basic concepts of Kubernetes networking. Topics such as Kubernetes networking models, inter-pod communication, intra-pod communication, cluster services, and basic load balancing will not be covered, as in this book we are more concerned with bringing the cluster to a state of production readiness rather than digging into the basics, which you can learn about in introductory Kubernetes books.

In this chapter, we will focus on bringing the cluster networking...
