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.

Summary

In this chapter, you have learned about Kubernetes networking components and services that make a cluster ready for production. You developed the templates and configuration as code for these services with Ansible.

Despite the fact that some of these components come pre-deployed with AWS EKS, you still need to fine-tune their configurations to fulfill your cluster requirements for scaling, availability, security, and performance. You also deployed additional add-ons and services, including ExternalDNS and NGINX Ingress Controller, that proved to be essential for Kubernetes' networking needs.

By using the Ansible configuration management solution that we introduced in the previous chapter, writing the Kubernetes manifests of these services becomes simple, scalable, and maintainable. We follow the same framework and steps to configure each service, and this is repeated for all services and add-on configurations that you will develop during this book.
