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 10. Designing for High Availability and Scalability

This chapter will cover advanced concepts such as high availability, scalability, and the requirements that Kubernetes operators will need to cover in order to begin to explore the topic of running Kubernetes in production. We'll take a look at the Platform as a Service (PaaS) offerings from Google and Azure and we'll use the familiar principles of running production workloads in a cloud environment.

We'll cover the following topics in this chapter:

  • Introduction to high availability
  • High availability best practices
  • Multi-region setups
  • Security best practices
  • Setting up high availability on the hosted Kubernetes PaaS
  • Cluster life cycle events
  • How to use admission controllers
  • Getting involved with the workloads API
  • What is a custom resource definition (CRD)?
