Getting Started with Kubernetes, Second Edition - Second Edition

By: Jonathan Baier

Overview of this book

Kubernetes has continued to grow and achieve broad adoption across various industries, helping you to orchestrate and automate container deployments on a massive scale. This book will give you a complete understanding of Kubernetes and how to get a cluster up and running. You will develop an understanding of the installation and configuration process. The book will then focus on the core Kubernetes constructs such as pods, services, replica sets, replication controllers, and labels. You will also understand how cluster level networking is done in Kubernetes. The book will also show you how to manage deployments and perform updates with minimal downtime. Additionally, you will learn about operational aspects of Kubernetes such as monitoring and logging. Advanced concepts such as container security and cluster federation will also be covered. Finally, you will learn about the wider Kubernetes ecosystem with OCP, CoreOS, and Tectonic and explore the third-party extensions and tools that can be used with Kubernetes. By the end of the book, you will have a complete understanding of the Kubernetes platform and will start deploying applications on it.

Preface

Introduction to federation


While federation is still very new in Kubernetes, it lays the ground work for the highly sought cross-cloud provider solution. Using federation, we can run multiple Kubernetes clusters on-premise and in one or more public cloud providers and manage applications utilizing the entire set of all our organizational resources.

This begins to create a path for avoiding cloud provider lock-in and highly available deployment that can place application servers in multiple clusters and allow for communication to other services located in single points among our federated clusters. We can improve isolation on outages at a particular provider or geographic location while providing greater flexibility for scaling and utilizing total infrastructure.

Currently, the federation plane supports these resources (ConfigMap, DaemonSets, Deployment, Events, Ingress, Namespaces, ReplicaSets, Secrets, and Services). Note that federation and its components are in alpha and beta phases of...
