Getting Started with Kubernetes - Third Edition

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.

The Kubernetes system

To understand the complex architecture and components of Kubernetes, we should take a step back and look at the landscape of the overall system in order to understand the context and place of each moving piece. This book focuses mainly on the technical pieces and processes of the Kubernetes software, but let's examine the system from a top-down perspective. In the following diagram, you can see the major parts of the Kubernetes system, which is a great way to think about the classification of the parts we'll describe and utilize in this book:

Let's take a look at each piece...
