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 8: Deploying Seamless and Reliable Applications

In previous chapters, we learned how to prepare our platform and infrastructure components for production usage. We also learned Kubernetes data management considerations and storage best practices to deploy our first stateful application using the Operator Framework. One of the most underestimated topics in container orchestration is container image management. Although developing applications in Kubernetes is out of the scope of this book, we need to understand the critical components of our images. There are multiple sources, public container registries, and vendors where we can find ready-to-consume application images. Mishandling container images can not only cause overutilization of our cluster resources but, more importantly, can also impact the reliability and security of our services.

In this chapter, we will discuss topics such as containers and image management. We will learn about the technical challenges when selecting...
