Key benefits

Understand the features of CoreOS and learn to administrate and secure a CoreOS environment
Develop, test, and deploy cloud services and applications more quickly and efficiently inside lightweight containers using CoreOS
This is a complete tutorial on CoreOS, which is the preferred OS for cloud computing as it contains components that facilitate cloud management

Description

CoreOS is an open source operating system developed upon the Linux kernel. The rise of CoreOS is directly related to the rise of Docker (a Linux container management system). It is a minimal operating system layer and takes a different approach to automating the deployment of containers. The major difference between CoreOS and other Linux distributions is that CoreOS was designed to deploy hundreds of servers. CoreOS immensely helps the users to create systems, which are easy to scale and manage, making life easier for all, be it developer, QA, or deployer. This book is all about setting up, deploying, and using CoreOS to manage clusters and clouds. It will help you understand what CoreOS is and its benefits as a cloud orchestration platform. First, we’ll show you how to set up a simple CoreOS instance with single node in the cluster and how to run a Docker container inside the CoreOS instance. Next, you’ll be introduced to Fleet and systemd, and will deploy and distribute Docker services across different nodes in cluster using Fleet. Later, you’ll be briefed about running services in a cluster with constraints, publishing the services already running on the cluster to new services, and making your services interact with each other. We conclude by teaching you about advanced container networking. By the end of the book, you will know the salient features of CoreOS and will be able to deploy, administrate, and secure a CoreOS environment.

Who is this book for?

This book is for cloud or enterprise administrators and application developers who would like to gain knowledge about CoreOS to deploy a cloud application or micro-services on a cluster of cloud servers. It is also aimed at administrators with basic networking experience. You do not need to have any knowledge of CoreOS.

What you will learn

Understand the benefits of CoreOS as a cloud orchestration platform
Learn about lightweight containers and various container frameworks such as Docker and RKT in CoreOS
Manage services and containers across cluster using Fleet and systemd
Set up a CoreOS environment using Vagrant
Create and manage CoreOS clusters
Discover the service parameters using etcd

Folks who are reading to keep up to date with the latest IT news would have certainly heard about CoreOs. Lots of people still have no idea what it is and how CoreOs differs from conventional Linux flavored OSes. I was one among the novices who came across this book with the same agenda. For a first timer who is picking up the nuances of Dockers, this book is a good first read.This is a useful background info for anyone trying to hack their way into the world of containers What is it in this book that a google search cannot answer was the my obvious question. In retrospect, the background of why containers are used in CoreOs and the differentiation between CoreOs and regular flavors of Linux Distributions is explained in detail.The steps detailed in setting up CoreOs as a standalone host, along with examples on CoreOs clustering will be useful for a beginner as well as an expert.The book is concise (170 pages from Start to End)for the amount of information and the number of examples it packs.If I were to nitpick, it would be on the textbook like approach of the book. For folks who are used to the Dummies and O'Reilly style of Narration, this book is a departure with its straight and linear approach to the topic of CoreOs.

My concerns with this book were confirmed. Maybe there just isn't enough about CoreOS to make a book just about CoreOS. That could be a good thing for CoreOS. While there is a bit about CoreOS, It seems like most of this book is mostly about Vagrant, Docker, and provisioning coreOS VMs with Vagrant. I also wish there were a repository to copy the code from so that I didn't have to retype it all in myself manually. I often find it a problem to figure out if I mistyped something or the book had another syntax typo that I am unfamiliar with like the ExecStartPre missing an equals sign in ExecStart docker on 1316 at the time of this writing. I wasted a lot of time retyping/finding mistakes in this book that prevented examples from working. I'm sorry to say I would not recommend this book, and it was definitely not worth the $20 I spent on it.
