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.

Configuring the Amazon CNI plugin

In Kubernetes, the Container Network Interface (CNI) provides a specification and framework for writing container network plugins to manage container networking, including pod communication and IP Address Management (IPAM). In the context of this book, we will not go into the details of the CNI plugins and how they work. What does concern us is how to make the best use of the CNI plugin, and how to configure it properly.

There are multiple CNI plugins that have been battle-tested over the years. Some of these satisfy the needs of general use cases, such as Calico, which is a highly recommended CNI plugin, while there are other CNI plugins that lean toward solving specific use cases.

The list of production tested CNI plugins includes Calico, Cilium, Azure CNI, Contiv, Flannel, Weave Net, and AWS CNI. The list goes on. You can get a comprehensive list of the supported CNI plugins and their features from the Kubernetes official documentation at...
