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.

Preparing Terraform

Before creating the Terraform configuration and code for the Kubernetes cluster, you need to create a new source code repository for the infrastructure and then create the Terraform directory structure. In addition to that, you will learn how to configure and use Terraform's shared state, which is an essential best practice for managing IaC in production environments.

Terraform directory structure

The Terraform directory is where all the Terraform source code lives in your source code repository. I recommend creating a separate source code repository. This repository should contain all the infrastructure code and configuration. The following is the directory structure of the Terraform source code that we will develop in the forthcoming sections:

Persisting the Terraform state

Terraform stores the state of the infrastructure resources under its management to be able to map it...
