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.

Why are containers so cool?


What's also really exciting is that not only has the open source community embraced containers and Kubernetes, but the cloud providers have also deeply embraced the container ecosystem, and invested millions of dollars in supporting tooling, ecosystem, and management planes that can help manage containers. This means you have more options to run container workloads, and you'll have more tools to manage the scheduling and orchestration of the applications running on your clusters.

We'll explore some specific opportunities available to Kubernetes users, but at the time of this book's publishing, all of the major cloud service providers (CSPs) are offering some form of hosted or managed Kubernetes:

  • Google Cloud Platform: GCP offers the Google Kubernetes Engine (GKE) (for more information visit https://cloud.google.com/kubernetes-engine/), a powerful cluster manager that can deploy, manage, and scale containerized applications in the cloud. Google has been running containerized workloads for over 15 years, and this platform is an excellent choice for sophisticated workload management:

When you take advantage of one of these systems, you get built-in management of your Kubernetes cluster, which allows you to focus on the optimization, configuration, and deployment of your cluster.
