Using Docker: Developing and Deploying Software with Containers 1st Edition

This book was exactly what I was looking for in regards to learning Docker. The beginning chapters gave clear insight into the history of Docker and how it evolved from virtual machines. I got a good sense of the purpose of Docker and why so many people are excited about it.Where this book was great for me was in the 6th chapter where the author shows how to create a simple web app in Docker. For awhile, I've been trying to deploy some Python code online and I was not sure how. This chapter was coincidentally programmed in Python using the Flask framework. I cloned the github resource for chapter 6, and plugged in some of my code. Within less than an hour I had my code running on localhost the way I wanted!The author is extremely knowledgeable about Docker and takes the time to point out many gotchas along the way in footnotes. I appreciated this attention to detail. He also evaluates a lot of addons and tools that work with Docker, and the trade-offs were presented well explaining exactly why you would use one tool over another. At points he mentions which technologies are still evolving, and where to check for updates.The last few chapters in this book were heavily into the networking side of things. Some of the material was quite advanced information about production systems.One minor issue with this book is that there are quite a few typos. I noticed one spelled "oen", and chapter spelled "chpater" in the book. Also, there was one place where "was were" was in a sentence, along with a few sentences not starting with capitals... I was seriously wondering how a spell checker did not catch these. I am still giving a 5-star rating though because the author's examples happened to be in the programming language I am using with an example to do exactly what I wanted. Additionally, I am happy to see how recent the information in this book is, even if it means there will be typos.

Helps with mindshift as well as setting out key points in usage. Took this prehistoric physicist/programmer from a monolithic C/C++/*NIX viewpoint to appreciating microservices in a mix of languages. Docker having developed in the months since publication, the Docker web pages must be consulted for up-to-date usage but most of the fundamentals here can still be used.

Please, don't get the headline wrong, this is not a bad book. It provides good coverage of Docker, but there are too many detailed examples that take away the real purpose of a Docker textbook, which should be teaching someone the philosophy and the design of Docker.There are chapters on the design of Docker, but the chapters filled with many overly detailed examples tend to put themselves into the focus.However, it seems that a book on Docker actually can't go too much into the above-described "grand" subjects. Why? Because Docker is largely made of smoke that hovers over the core elements provided by the Linux kernel, which are the control groups, namespaces and filesystems. The smoke is the DockerHub.This is by no means a bad book. It just isn't what a textbook should be, but I've already described why.

So far this is an excellent book. Learning a lot. It is for the person who will deploy containers. Not for the person who want to create containers from scratch.

Not the details I was looking for; running HA environments for the past 20 years was looking for a bit more insight.

Very useful

Out of date. It's bad--> really bad they are selling this. It's a 9 year old tech book. The commands don't work so it's useless. I'll try and return but...

Very good book, LOTs of information, relevant examples, and they actually work! Additionally he does a good job of helping with people using boot2docker.
