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.

Validating cluster quality

In this section, we will learn about some of the best practices and tools in the ecosystem to improve different aspects of our Kubernetes clusters. Continuous improvement is a wide-ranging concept that encompasses everything from providing a smooth platform to services on Kubernetes and setting a particular Quality of Service (QoS) for resources, to making sure resources are evenly distributed and unused resources are released to reduce the pressure on cluster resources and the overall cost of providing services. The definition of improvement itself is gradually getting more granular, and it is not limited to the practices that we will discuss here. Before we learn about the conformance and cost management tools, let's learn about a few common-sense quality best practices we should consider:

  • Generate state-of-cluster reports: Although it is expected that Kubernetes clusters should behave the same whether it's a managed Kubernetes service...
