Descripción del producto
Reseña del editor
The idea behind Docker, a free an open source program, is simple. Create a tiny virtual environment, called a container, for an application that includes only its particular set of dependencies. The Docker engine accounts for, manages, and builds these containers through functionality provided by the host operating system. Software running inside containers share the Linux OS and other resources, making their footprints radically smaller, and the containerized applications easy to install, manage, and remove. Applications can be packaged without worrying about environment-specific deployment concerns, and the operations team gets cleaner, more efficient systems across the board.
Docker in Action starts with a clear explanation of the Docker model of virtualization and shows how to create, deploy, and manage applications hosted in Docker containers. It offers specific techniques for testing and distributing applications via Docker Hub and other registries. It shows how to take advantage of the Linux OS features that Docker uses to run programs securely, and how to manage shared resources. Using carefully-designed examples, the book guides readers on orchestrating containers and applications from installation to removal. Along the way, it teaches techniques for using Docker on systems ranging from personal dev-and-test machine to full-scale cloud deployments.
Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.

Anyway, good book. It covers the concepts well in addition to providing examples you can easily follow along with and best practices. There was even a scavenger hunt activity to get you familiar with search. I also liked the disclaimers about chaning tech and how to excuse the poor passwordss “suppose the DBA is a cat lover and hates strong passwords”
My favorite chapter was chapter 9 (which is online for free at Manning's site). In addition to explaining different models, it had a comparison table on how each hosting mechanism scores on various attributes with notes on each. It also had a great diagram for each. My second favorite chapter was chapter 8 which covers each of the instructions for a docker file.
So what prevented me from giving a perfect score? Little things. There's a reference to Appendix B, but no Appendix. I'd have liked a comparison of all the models (without notes) in Chapter 9. There were some forward references that confused me. Nothing terrible, but I can't give a perfect star rating. I still recommend you buy the book. It's great for getting started with Docker or learning about best practices.
Disclosure: I received a copy of this book from the publisher in exchange for writing this review on behalf of CodeRanch.
Via concise, explicative prose you will learn how to:
* install Docker locally and on various popular cloud compute platforms
* run applications in containers
* run application stacks composed of multiple containers
* run your own Docker registry
* run your own Docker cluster, and a good deal more
I am usually a little more skeptical of technical books such as this where the information could become quickly outdated, however this book really focuses a lot on the underlying idea that is Docker and some of the fundamental architectural decisions that were used. These are all still pertinent and I found so many little gems within this book that I would easily recommend it to both the docker beginner and the advanced docker user. I especially liked his take on using docker for, well everything, even `curl`.
To get the most of out of this book you will, of course, want to follow along and try the examples that are provided (to the best of your ability) and while a large portion of the book is on image management (layers, creation, distribution, registry) there is a lot on other aspects of docker including network, security (isolation) and even ideas on when and where to use docker.
There are a few things that are outdated that you should be aware of. Since this book has been written the docker organization has released their "docker for mac" solution that replaces the boot2docker tool described in the book. This makes some of the examples much easier to try. Chapter 12 (Docker Swarm) is also outdated from the major changes swarm went through with 1.12, however the content in the chapter is fantastic. And of course this is before the release of the new native Windows Docker Host, so there is no information on the nanokernel or Dockerfiles using Powershell in the book.
