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.

As a refresher, let's remind ourselves about the entire Kubernetes system, so we can understand conceptually where the ecosystem referred to in this chapter sits:

In this chapter, we're talking about the top, greenest layer in the preceding diagram. This layer is made up of hundreds of companies and products that power the software and frameworks needed to run Kubernetes at scale. You can find the highest level of grouping of this layer in a couple of places:

  • The first place to check is the Kubernetes Community GitHub repository:
    • You can find the repository at https://github.com/kubernetes/community, and it's a good starting point for anyone who's interested in joining the code-powered portions of the Kubernetes system. In the preceding diagram, consider the layers nucleus through interface, that is, layers one through four. Here's where we'll find the Special Interest Groups (SIGs), which will allow us to branch us out into the ecosystem layer where we can explore the supporting...
