Creating Kubernetes Clusters

In the previous chapter, we learned what Kubernetes is all about, how it is designed, what concepts it supports, how to use its runtime engines, and how it fits within the CI/CD pipeline.

Creating a Kubernetes cluster is a non-trivial task. There are many options and tools to select from, and there are many factors to consider. In this chapter, we'll roll up our sleeves and build some Kubernetes clusters. We will also discuss and evaluate tools such as Minikube, kubeadm, kube-spray, bootkube, and stackube. We will also look into deployment environments, such as local, cloud, and bare metal. The topics we will cover are as follows:

Creating a single-node cluster with Minikube
Creating a multi-node cluster using kubeadm
Creating clusters in the cloud
Creating bare-metal clusters from scratch
Reviewing other options for creating Kubernetes clusters...

Key benefits

•Explore the latest features available in Kubernetes 1.10

•Ensure that your clusters are always available, scalable, and up to date

•Master the skills of designing and deploying large clusters on various cloud platforms

Description

Kubernetes is an open source system that is used to automate the deployment, scaling, and management of containerized applications. If you are running more containers or want automated management of your containers, you need Kubernetes at your disposal. To put things into perspective, Mastering Kubernetes walks you through the advanced management of Kubernetes clusters. To start with, you will learn the fundamentals of both Kubernetes architecture and Kubernetes design in detail. You will discover how to run complex stateful microservices on Kubernetes including advanced features such as horizontal pod autoscaling, rolling updates, resource quotas, and persistent storage backend. Using real-world use cases, you will explore the options for network configuration, and understand how to set up, operate, and troubleshoot various Kubernetes networking plugins. In addition to this, you will get to grips with custom resource development and utilization in automation and maintenance workflows. To scale up your knowledge of Kubernetes, you will encounter some additional concepts based on the Kubernetes 1.10 release, such as Promethus, Role-based access control, API aggregation, and more. By the end of this book, you’ll know everything you need to graduate from intermediate to advanced level of understanding Kubernetes.

Who is this book for?

Mastering Kubernetes is for you if you are a system administrator or a developer who has an intermediate understanding of Kubernetes and wish to master its advanced features. Basic knowledge of networking would also be helpful. In all, this advanced-level book provides a smooth pathway to mastering Kubernetes.

What you will learn

•Architect a robust Kubernetes cluster for long-time operation

•Discover the advantages of running Kubernetes on GCE, AWS, Azure, and bare metal

•Understand the identity model of Kubernetes, along with the options for cluster federation

•Monitor and troubleshoot Kubernetes clusters and run a highly available Kubernetes

•Create and configure custom Kubernetes resources and use third-party resources in your automation workflows

•Enjoy the art of running complex stateful applications in your container environment

•Deliver applications as standard packages

One one hand, you want to find a place that have all the information you need to know about Kubernetes. This might be a good candidate. However, on the other hand, it's not easy to cover every topic in detail. You will still need to dive into technical blogs with more explanation.

Very outdated (about K8s 1.10 with 1.17 available) with very simple describing problems and especially solutions. Many chapters ends with "now you know how" but no, we just read some headlines about it and not really knew them yet. Many excuses like "I use this because Ubuntu distro is broken" which is false statement. Some like "you will see an error but nevermind". Why shouldn't I not mind an error?As well as second edition it should be better checked for mistyping like "Promethus" instead of "Prometheus".

This book is terrible. It reads like a blog of someone’s notes...not well thought out. Software referenced is seriously outdated. The previous 5 star reviews had to have been bought.

This book helped me cofound my own startup. An inspirational read by an inspirational author.

In "Mastering Kubernetes" 2nd Edition Gigi takes on a very ambitious task, which is to explain the intrinsics all the way up to the master-plan of a large open-source projects such as Kubernetes and several other supporting projects (such as Helm, Docker and others). In fact, it is not hard to imagine a series of 14 books, each one created out of this book's 14 chapters. Whether it's "Configuring Kubernetes Security", "Advanced Kubernetes Networking" etc, there is so much information in each chapter that can easily be extended to a whole book. Alas, you cannot help but feel that some compromise had been made in order to fit all this material into one book.This is by no means a "for dummies" book, although it goes through some basic Kubernetes terminology it does not attempt to teach you everything from the ground up. It is also not a reference guide, it will not cover every single API call that is available in the Kubernetes world, you will have to go online and research that yourself.In its fun and light-handed way, Gigi compresses the vast coverage of the material by choosing to go over only the practical aspects of Kubernetes, and its supporting projects which Gigi believes you will most likely want to consider for your current or future projects. It is encouraging to read a book that is written by an actual implementer of systems and not just a theoretical practitioner. If you already have a good grasp of Kubernetes but you wish to learn from the experiences of a fellow Kubernetes expert, the price of this book is a small price to pay for such a great knowledge exchange.
