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.

Running Kubernetes on Multiple Clouds and Cluster Federation

In this chapter we'll take it to the next level, and look at running Kubernetes on multiple clouds and cluster federation. A Kubernetes cluster is a close-knit unit in which all the components run in relative proximity and are connected by a fast network (a physical data center or cloud provider availability zone). This is great for many use cases, but there are several important use cases where systems need to scale beyond a single cluster. Kubernetes federation is a methodical way to combine multiple Kubernetes clusters and interact with them as a single entity. The topics we will cover include the following:

  • A deep dive into what cluster federation is all about
  • How to prepare, configure, and manage a cluster federation
  • How to run a federated workload across multiple clusters
