Learning CoreOS

Key Features

• 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 light weight containers using CoreOS.
• A complete tutorial on CoreOS, which is the preferred OS for cloud computing as it only contains components that facilitate cloud management

Book Description

CoreOS is an Open Source operating system developed upon the Linux Kernel. The rise of CoreOS is directly related with 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.

This book is all about setting up, deploying, and using it for managing clusters and clouds. The books start with the explanation about other available orchestration for virtual machines by also setting the context on what is the need for CoreOS in the first place and the problems it solves. It makes us understand what CoreOS is and its benefits as a cloud orchestration platform. Then we are taught to set up a simple CoreOS instance with single node in the cluster and run docker container inside the CoreOS instance. The book then proceeds to introduce us to Fleet and Systemd, deploy and distribute docker services across different nodes in cluster using Fleet. Later, we are briefed about running services in cluster with constraints, publishing the services already running in the cluster to new services, and making your service interact with each other. The book concludes by teaching us about the advanced Container networking. By the end of the book, the readers will know the salient features of CoreOS and will be able to deploy, administrate, and secure a CoreOS environment.

What you will learn
