How does one "master" docker when there is not a single word about layers?
How does one "master" docker when you have "sudo apt update && sudo apt install -y git" with a description of "so it doesn't have to wait for one process to end to start the other"?
This is another book coming from a book farm where people write about things they don't know properly. This is another book coming from a book farm where reviewers seem picked in the basis of "does not know enough about the subject to not make a fuss so we can publish it as soon as possible".
If you want to learn about docker, stay away from this book. It will do more harm than good.
I'm going to be honest: I had higher hopes for a book about "mastering" a topic. This isn't a truly bad book, if you are completely new to Docker. It is basically an extended tutorial that explains all the different commands. What I would have liked to have seen was less time spent on all the potential command variants and more time on the concepts and under-the-cover workings of the technology.
A good book to read to understand Docker and to start off with it. Definitely not one which will give one a mastery over Docker. In depth coverage required for mastering Docker is missing.
This book covers pretty much everything you need to know about this amazing technology called Docker. But. While reading it, I had a feeling that something is not covered. And sometimes I had to figure things out by my own. Also, if you are not familiar with Linux, this book might be a little bit difficult.
Yet I must say, Mr.Gallaher did a good job explaining all of this. Even considering what I said before, it's a good book to learn Docker.
