you know how to install, upgrade, and remove packages.

Git

Git has established itself as the standard for distributed version control. If you are

already familiar with CVS and SVN, but have not yet used Git, you should. Ver‐

sion Control with Git by Jon Loeliger and Matthew McCullough (O’Reilly) is a

good start. Together with Git, the GitHub website is a great resource to get

started with a hosted repository of your own. To learn GitHub, try http://train‐

ing.github.com and the associated interactive tutorial.

Python

In addition to programming with C/C++ or Java, I always encourage students to

pick up a scripting language of their choice. Perl used to rule the world, while

these days, Ruby and Go seem to be prevalent. I use Python. Most examples in

this book use Python, but there are a few examples with Ruby, and one even uses

Clojure. O’Reilly offers an extensive collection of books on Python, including

Introducing Python by Bill Lubanovic, Programming Python by Mark Lutz, and

Python Cookbook by David Beazley and Brian K. Jones.

Vagrant

Vagrant has become one of the great tools for DevOps engineers to build and

manage their virtual environments. It is best suited for testing and quickly provi‐

sioning virtual machines locally, but also has several plug-ins to connect to public

cloud providers. This book uses Vagrant to quickly deploy a virtual machine

instance that acts as a docker host. You might want to read Vagrant: Up and Run‐

ning from the author of Vagrant itself, Mitchell Hashimoto.

Docker is written in Go. Over the last couple of years, Go has established itself as

the new programming language of choice in many start-ups. This cookbook is

not about Go programming, but it shows how to compile a few Go projects.

Some minimal understanding of how to set up a Go workspace will be handy. If

you want to know more, the “Introduction to Go Programming” video training

course is a good start.

Online Content

Code examples, Vagrantfiles, and other scripts used in this book are available at Git‐

Hub. You can clone this repository, go to the relevant chapter and recipe, and use the

code as is. For example, to start an Ubuntu 14.04 virtual machine using Vagrant and

install Docker:

Job for docker.service failed because start of the service was attempted too often. See "systemctl status docker.service" and "journalctl -xe" for details. To force a start use "systemctl reset-failed docker.service" followed by "systemctl start docker.service" again.

Redirecting to /bin/systemctl start docker.service Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

Failed to start docker.service: Unit docker.service has a bad unit file setting. See system logs and 'systemctl status docker.service' for details.
