Getting Started with Kubernetes

Getting Started with Kubernetes

By: Jonathan Baier, 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.

Upgrading the cluster

In order to run your cluster over long periods of time, you'll need to update your cluster as needed. There are several ways to manage cluster upgrades, and the difficulty level of the upgrades is determined by the platform you've chosen previously. As a general rule, hosted Platform as a service (PaaS) options are simpler, while roll your own options rely on you to manage your cluster upgrades.

Upgrading PaaS clusters

Upgrading PaaS clusters is a lot simpler than updating your hand-rolled clusters. Let's check out how the major cloud service providers update their hosted Kubernetes platforms.

With Azure, it's relatively straightforward to manage an upgrade of both the control plane...
