Preface

Get started with Docker, the Linux containerizing technology that has revolutionized application sandboxing. With this book, you will be able to learn how to use Docker to make your development faster and your deployment of applications simpler.

This guide will show you how to build your application in sandboxed Docker containers and make them run everywhereyour development machine, your private server, or even on the cloud, with a fraction of the cost of a virtual machine. Build a PaaS, deploy a cluster, and so on, all on your development setup.

What this book covers

, Unboxing Docker , teaches you how to get Docker running in your environment.

, Docker CLI and Dockerfile , helps you to acclimatize to the Docker command-line tool and start building your own containers by writing Dockerfiles.

, Configuring Docker Containers , shows you how to control your containers and configure them to achieve fine-grained resource management.

, Automation and Best Practices , covers various techniques that help manage containersco-ordinating multiple services using supervisor, service discovery, and knowledge about Docker's security.

, Friends of Docker , shows you the world surrounding Docker. You will be introduced to open source projects that use Docker. Then you can build your own PaaS and deploy a cluster using CoreOS.
