Mastering Kubernetes - Second Edition

By: Gigi Sayfan

Overview of this book

Kubernetes is an open source system that is used to automate the deployment, scaling, and management of containerized applications. If you are running more containers or want automated management of your containers, you need Kubernetes at your disposal. To put things into perspective, Mastering Kubernetes walks you through the advanced management of Kubernetes clusters. To start with, you will learn the fundamentals of both Kubernetes architecture and Kubernetes design in detail. You will discover how to run complex stateful microservices on Kubernetes including advanced features such as horizontal pod autoscaling, rolling updates, resource quotas, and persistent storage backend. Using real-world use cases, you will explore the options for network configuration, and understand how to set up, operate, and troubleshoot various Kubernetes networking plugins. In addition to this, you will get to grips with custom resource development and utilization in automation and maintenance workflows. To scale up your knowledge of Kubernetes, you will encounter some additional concepts based on the Kubernetes 1.10 release, such as Promethus, Role-based access control, API aggregation, and more. By the end of this book, you’ll know everything you need to graduate from intermediate to advanced level of understanding Kubernetes.

Managing a Kubernetes cluster federation

Managing a Kubernetes cluster federation involves many activities above and beyond managing a single cluster. There are two ways to set up the federation. Then, you need to consider cascading resource deletion, load balancing across clusters, fail over across clusters, federated service discovery, and federated discovery. Let's go over each one in detail.

Setting up cluster federation from the ground up

Note: this approach is now deprecated in favor of using Kubefed. I describe it here for the benefit of readers using older versions of Kubernetes.

To set up a Kubernetes cluster federation, we need to run the components of the control plane, which are as follows:
