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 4: Managing Cluster Configuration with Ansible

In Chapter 3, Provisioning Kubernetes Clusters Using AWS and Terraform, you learned how to create a Kubernetes infrastructure with Terraform and AWS, and you also learned how to develop infrastructure as code and provisioned your first production-like cluster.

This was just the first step towards building operational and production-ready Kubernetes clusters. By now, you should have an up-and-running cluster with Terraform infrastructure modules to provision other similar clusters.

These clusters are still plain; they're not configured or optimized to run production workloads. To make these clusters fully operational, we simply need to deploy and configure the required Kubernetes services for them.

In this chapter, you will design and develop a configuration management solution that you can use to manage the configuration of Kubernetes clusters and their supporting services. This solution is automated and scalable...
