Docker Engine allows every value-adding software solution to be containerized, indexed, registered, and stocked. Docker is turning out to be a great tool for systematically developing, shipping, deploying, and running containers everywhere. While docker.io lets you upload your Docker creations to its registry for free, anything you upload there is publicly discoverable and accessible. Innovators and companies aren't keen on this and therefore insist on private Docker Hubs. In this chapter, we explained all the steps, syntaxes, and semantics for you in an easy-to-understand manner. We showed how to retrieve images to generate Docker containers, and described how to push our images to Docker Registry in a secure manner in order to be found and used by authenticated developers. The authentication and authorization mechanisms, a major part of the whole process, have been explained in detail. Precisely speaking...

Overview of this book
Docker is an open source containerization engine that offers a simple and faster way for developing and running software. Docker containers wrap software in a complete filesystem that contains everything it needs to run, enabling any application to be run anywhere – this flexibily and portabily means that you can run apps in the cloud, on virtual machines, or on dedicated servers.
This book will give you a tour of the new features of Docker and help you get started with Docker by building and deploying a simple application. It will walk you through the commands required to manage Docker images and containers. You’ll be shown how to download new images, run containers, list the containers running on the Docker host, and kill them.
You’ll learn how to leverage Docker’s volumes feature to share data between the Docker host and its containers – this data management feature is also useful for persistent data. This book also covers how to orchestrate containers using Docker compose, debug containers, and secure containers using the AppArmor and SELinux security modules.
