Overview of this book

Thanks to its extensive support for managing hundreds of containers that run cloud-native applications, Kubernetes is the most popular open source container orchestration platform that makes cluster management easy. This workshop adopts a practical approach to get you acquainted with the Kubernetes environment and its applications. Starting with an introduction to the fundamentals of Kubernetes, you’ll install and set up your Kubernetes environment. You’ll understand how to write YAML files and deploy your first simple web application container using Pod. You’ll then assign human-friendly names to Pods, explore various Kubernetes entities and functions, and discover when to use them. As you work through the chapters, this Kubernetes book will show you how you can make full-scale use of Kubernetes by applying a variety of techniques for designing components and deploying clusters. You’ll also get to grips with security policies for limiting access to certain functions inside the cluster. Toward the end of the book, you’ll get a rundown of Kubernetes advanced features for building your own controller and upgrading to a Kubernetes cluster without downtime. By the end of this workshop, you’ll be able to manage containers and run cloud-based applications efficiently using Kubernetes.

Building a High-Availability Focused Kubernetes Cluster

Hopefully, by reading the previous section, you're starting to realize that Kubernetes is less magical than it may seem when you first approached the topic. It is an extremely powerful tool on its own, but Kubernetes really shines when we take full advantage of its capability of running in a highly available configuration. So now we're going to see how to implement it and actually build a cluster using a cluster life cycle management tool. But before we do that, we need to know the different ways that we can deploy and manage a Kubernetes cluster.

Self-Managed versus Vendor-Managed Kubernetes Solutions

Amazon Web Services, Google Cloud Platform, Microsoft Azure, and practically every other major cloud services provider has a managed Kubernetes offering. So, when you are deciding how you are going to build and run your cluster, you should consider some of the different managed providers and their strategic offerings...
