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 15. Kubernetes Infrastructure Management

In this chapter, we'll discuss how to make changes to the infrastructure that powers your Kubernetes infrastructure, whether or not it is a purely public cloud platform or a hybrid installation. We'll discuss methods for handling underlying instance and resource instability, and strategies for running highly available workloads on partially available underlying hardware. We'll cover a few key topics in this chapter in order to build your understanding of how to manage infrastructure in this way:

  • How do we plan to deploy Kubernetes components?
  • How do we secure Kubernetes infrastructure?
  • How do we upgrade the cluster and kubeadm?
  • How do we scale up the cluster?
  • What external resources are available to us?

In this chapter, you'll learn about the following:

  • Cluster upgrades
  • How to manage kubeadm
  • Cluster scaling
  • Cluster maintenance
  • The SIG Cluster Lifecycle group
