Docker Containers : Build and Deploy with Kubernetes, Flannel, Cockpit, and Atomic

The Practical Guide to Running Docker on Linux Systems or Cloud Environments

Whether on your laptop or a remote cloud, Docker can transform how you create, test, deploy, and manage your most critical applications. In Docker Containers, Christopher Negus helps you master Docker containerization from the ground up.

You’ll start out running a few Docker container images in Ubuntu, Fedora, RHEL, CoreOS, or Project Atomic. By the time you’ve finished, you’ll be deploying enterprise-quality, multi-container Kubernetes setups in modern Linux and cloud environments.

Writing for system administrators, software developers, and technology enthusiasts, Negus touches on every aspect of working with Docker: setting up containerized applications, working with both individual and multiple containers, running containers in cloud environments, and developing containers.

Teaching through realistic examples of desktop applications, system services, and games, Negus guides you through building and deploying your own Dockerized applications. As you build your expertise, you’ll also learn indispensable Docker best practices for building and integrating containers, managing Docker on a day-to-day basis, and much more:

• Understanding what Docker is and what you can do with it
• Installing Docker on standard Linux or specialized container operating systems such as Atomic Host and CoreOS
• Setting up a container runtime environment and private Docker Registry
• Creating, running, and investigating Docker images and containers
• Finding, pulling, saving, loading, and tagging container images
• Pulling and pushing containers between local systems and Docker Registries
• Integrating Docker containers with host networking and storage
• Building containers with the docker build command and Dockerfile files
• Minimizing space consumption and erasing unneeded containers
• Accessing special host privileges from within a container
• Orchestrating multiple containers into complex applications with Kubernetes
• Using super privileged containers in cloud environments
• Managing containers in the cloud with Cockpit
• Getting started with Docker container development
• Learning container build techniques from shared Dockerfiles

Christopher Negus is a bestselling author of Linux books, a certified Linux instructor and examiner, Red Hat Certified Architect, and principal technical writer for Red Hat. At the moment, projects Chris is working on include Red Hat OpenStack Platform High Availability, Red Hat Enterprise Linux Atomic Enterprise, Kubernetes, and Linux Containers in Docker format.

As an author, Chris has written dozens of books about Linux and open source software. His Linux Bible, Ninth Edition, released in 2015, is consistently among the top-selling Linux books today. During the dotcom days, Chris’s Red Hat Linux Bible sold more than 250,000 copies in eight editions and was twice voted best Linux book of the year. Other books authored or coauthored by Chris include the Linux Toolbox series, Linux Toys series, Fedora and Red Hat Enterprise Linux Bible series, and Linux Troubleshooting Bible with Wiley Publishing.

With Prentice Hall, Chris helped produce the Negus Software Solution Series. For that series, Chris wrote Live Linux CDs and coauthored The Official Damn Small Linux Book. That series also includes books on web development, Google Apps, and virtualization.

Chris joined Red Hat in 2008 as an RHCE instructor. For that role, he became a Red Hat Certified Instructor (RHCI) and Red Hat Certified Examiner (RHCX). In 2014, Chris became a Red Hat Certified Architect (RHCA), with certifications in Virtualization Administration, Deployment and Systems Management, Cluster and Storage Management, and Server Hardening. In 2011, Chris shifted from his Linux instructor role back to being a full-time writer for Red Hat, which he continues to do today.

Early in his career, Chris worked at UNIX System Laboratories and AT&T Bell Labs with the organizations that produced the UNIX operating system. During that time, Chris wrote the first official UNIX System V Desktop system manual and cowrote the Guide to the UNIX Desktop. For eight years, Chris worked closely with developers of the UNIX system, from UNIX System V Release 2.0 through Release 4.2.
