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.

Hosted platforms


There are several options available for hosted Kubernetes in the cloud. These Platforms as a service (PaaS) can provide a stable operating model as you push towards production. Here's an overview of the major PaaSes provided by Amazon, Microsoft, and Google.

Amazon Web Services

Elastic Container Service (ECS) has just been launched as of the time of this chapter's writing. AWS is preparing a networking plugin to differentiate itself from other offerings, called the vpc-cni. This allows for pod networking in Kubernetes to use Elastic Network Interfaces (ENIs) on AWS. With ECS, you do have to pay for manager nodes, which is a different path to that taken by Microsoft and Google. ECS' startup procedure is also currently more complex and doesn't have single-command creation via the CLI.

Microsoft Azure

The Azure Container Service is the second longest running hosted Kubernetes service in the cloud after the Google Kubernetes Engine. You can use Azure templates and the Resource Manager...
