You’ve heard about this thing called Docker. You see a friendly and innocuous whale as the Docker mascot. Everyone around you is abuzz with interest about Docker containers and how it’s the best thing since sliced bread (plain or toasted). You’ve tried to look into this container technology thingy; out jump spectres called cgroups, namespaces, kernels, and virtual machines. Morale breaks and you run for the hills, screaming.
Fear not! It’s time to rally. Using Docker is actually not that hard. I’ve taught a diverse array of people (hobby hackers, biochemists, professional software engineers, to name a few) just enough Docker to be dangerous. It’s your turn.
Full disclosure: I was given the opportunity to read an early version of the book and make small suggestions. However, I do not profit from this book's success.
Reading this book was at least the fourth time I've attempted to learn Docker and after doing so it's difficult to remember what I found so hard about it. The author takes everything step by step, giving enough information to make the reader comfortable with the essentials without explaining every possible edge case or detail. This book can be completed in an afternoon which is enough to teach you the parts of Docker relevant to the average developer's use case. It's not going to teach you everything of course but you'll have a solid foundational understanding from which you should be easily able to add onto. There's humor in the book to keep it entertaining but it doesn't detract from the knowledge.
Before this book, I didn't see the point of Docker. Now, it's an essential and easy step in all of my projects.
The only ‘no shit’ book out there that can get you started on Docker in minutes!
The author has definitely underplayed the “I tried to keep it short”. I’d say the book is a masterclass in a crash course form. It is extremely well structured and thought out. A quick and potent read, full of fast and simple examples. It gives the learner a gratifying experience especially for those in a hurry to actually get started on a practical and relevant project. You will finish having a confident understanding of Docker.
Concise and friendly way of writing. Points are clearly laid out and doesn't beat around the bush. Definitely a must read if you are starting your Docker journey.
