Your one-stop guide for building, configuring, maintaining, and deploying one of the world's fastest growing OSes About This Book 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 Who This Book Is 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 Find out about chaining services running on the cluster using Flannel / Rudder and Weave Create a virtual tenant network and service chaining using OVS In Detail 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. Style and approach This practical guide covers the basics and advanced topics related to CoreOS and lightweight containers. The topics are covered in an easy-to-follow manner with each feature explained in detail, beginning with a brief overview and followed by an explanation of its corresponding configuration files.

Washington Territory, 1886 Jacob and Nell Ellstrom step from ship to shore and are struck dumb by the sight of their new home—the Harbor, a ragged township of mud streets and windowless shacks. In the years to come this will be known as one of the busiest and most dangerous ports in the world, and with Jacob's station as the only town physician, prosperity and respect soon rain down on the Ellstroms.

For fans of Downton Abbey . . . The peaceful beauty of the English countryside belies the turmoil of forbidden love and the apprehension of a changing world for the families of NetherwoodYorkshire, 1904. On Netherwood Common, Russian émigré Anna Rabinovich shows her dear friend Eve Williams a gracious Victorian villa—Ravenscliffe—the house Anna wants them to live in. There's a garden and a yard and room enough for their children to play and grow. Something about the house speaks to Anna, and you should listen to a house, she believes...Ravenscliffe holds the promise of happiness. Across the square, Clarissa and her husband, the Earl of Netherwood, are preparing for King Edward's visit.

Supplying a bustling industrial empire with the highest-quality coal keeps his coffers filled—money he needs to run his splendid estate, Netherwood Hall, and to dress his wife and daughters in the latest fashions. And keeping his heir, the charming but feckless Tobias, out of trouble, doesn't come cheap.Downstairs: Eve Williams, the wife of one of Lord Netherwood's most stalwart employees, cleverly manages her family's well-being on the low wages her hardworking husband earns in the mines. But when her ordered life amid the terraced rows of miners' houses is brought crashing down by the twin arrivals of tragedy and charity, Eve must look to her own self-sufficiency and talent to provide for her three young children. And soon the divide between "upstairs" and "downstairs" is about to close . . .and neither world will ever be the same.
