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. This book will give you a complete understanding of Kubernetes and how to get a cluster up and running. You will develop an understanding of the installation and configuration process. The book will then focus on the core Kubernetes constructs such as pods, services, replica sets, replication controllers, and labels. You will also understand how cluster level networking is done in Kubernetes. The book will also show you how to manage deployments and perform updates with minimal downtime. Additionally, you will learn about operational aspects of Kubernetes such as monitoring and logging. Advanced concepts such as container security and cluster federation will also be covered. Finally, you will learn about the wider Kubernetes ecosystem with OCP, CoreOS, and Tectonic and explore the third-party extensions and tools that can be used with Kubernetes. By the end of the book, you will have a complete understanding of the Kubernetes platform and will start deploying applications on it.

The rolling update feature can work well for a simple blue-green deployment scenario. However, in a real-world blue-green deployment with a stack of multiple applications, there can be a variety of interdependencies that require in-depth testing. The update-period command allows us to add a timeout flag where some testing can be done, but this will not always be satisfactory for testing purposes.

Similarly, you may want partial changes to persist for a longer time and all the way up to the load balancer or service level. For example, you may wish to run an A/B test on a new user interface feature with a portion of your users. Another example is running a canary release (a replica in this case) of your application on new infrastructure like a newly added cluster node.

Let's take a look at an A/B testing example. For this example, we will need to create a new service that uses sessionAffinity. We will set the affinity to ClientIP, which will allow us to forward...
