Getting Started with Kubernetes - Third Edition

By: Jonathan Baier, Jesse White

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. Based on the recent release of Kubernetes 1.12, Getting Started with Kubernetes gives you a complete understanding of how to install a Kubernetes cluster. The book focuses on core Kubernetes constructs, such as pods, services, replica sets, replication controllers, and labels. You will understand cluster-level networking in Kubernetes, and learn to set up external access to applications running in the cluster. As you make your way through the book, you'll understand how to manage deployments and perform updates with minimal downtime. In addition to this, you will explore operational aspects of Kubernetes , such as monitoring and logging, later moving on to advanced concepts such as container security and cluster federation. You'll get to grips with integrating your build pipeline and deployments within a Kubernetes cluster, and be able to understand and interact with open source projects. In the concluding chapters, you'll orchestrate updates behind the scenes, avoid downtime on your cluster, and deal with underlying cloud provider instability within your cluster. By the end of this book, you'll have a complete understanding of the Kubernetes platform and will start deploying applications on it.

Chapter 12: Cluster Federation and Multi-Tenancy


  1. 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 our organizational resources.
  2. Federation allows you increase the availability and tenancy capabilities of your Kubernetes clusters.
  3. Resource synchronization across clusters and multi-cluster service discovery.
  4. Kubefed.
  5. Federation-controller-manager and the federation-apiserver.
  6. HPAs will act in a similar fashion to normal HPAs, with the same functionality and same API-based compatibility—only, with federation, the management of pods will traverse your clusters.
  7. Deployments, ReplicaSets, Events, ConfigMaps, DaemonSets, Ingress, Namespaces, Secrets, and Services.
