Poulton - Docker Deep Dive

This is a book about Docker. No prior knowledge required! The motto of the book is Zero to Docker in a single book!

If youre interested in Docker and want to know how it works and how to do things properly this book is dedicated to you!

If you just want to use Docker, and you dont care if you get things wrong, this book is not for you.

Docker released its first professional certification in the fall of 2017. Its called the Docker Certified Associate (DCA) and its for people wanting to prove their mastery of Docker.

The exam objectives match a lot of real-world scenarios, so I decided to update the book so that it covered all objectives. In doing this, I worked extremely hard to keep the book interesting and applicable in the real world.

This is not an exam-cram book. Yes, it covers all exam topics, but this is a real-world book that is enjoyable to read.

At the time of publishing, this is the only resource available that covers the entire set of DCA exam objectives!

Good luck with your exam!

No offense Leanpub and Amazon Kindle, but as good as modern e-books are, Im still a fan of ink and paper! So. this book is available as a high-quality, full-color, paperback edition via Amazon. None of this black-and-white nonsense.

On the topic of Amazon Id love it if you could write a quick review on Amazon! You can even do this if you bought the book on Leanpub. Cheers!

Docker is here and theres no point hiding. Developers are all over it, and IT Ops need to be on their game! We damn well better know how to build and support production-quality containerized apps in our business-critical environments. This book will help you.

If you think Docker is just for developers, then prepare to have your world flipped on its head!

Containerized apps need somewhere to run and someone to manage them. If you think developers are going to do that, youre dreaming. Ops will need to build and run high-performance production-grade Docker infrastructures. If youve got an Ops focus and youre not skilled-up on Docker, youre in for a world of pain. But dont stress, the book will skill you up!

Yes. The book is usually more up to date and covers additional material.

If you like my video courses youll probably like the book. If you dont like my video courses you probably wont like the book.

If you havent watched my video courses, you should! Theyre fast-paced and fun and get rave reviews!

Ive divided the book into two sections:

• The big picture stuff
• The technical stuff

The big picture stuff section covers things like:

• Who is Docker, Inc.
• What is the Docker (Moby) project.
• What is the OCI.
• Why do we even have containers

Its the kind of stuff that you need to know if you want a good rounded knowledge of Docker and containers.

The technical stuff section is what the book is all about! This is where youll find everything you need to start working with Docker. It gets into the detail of images, containers, and the increasingly important topic of orchestration. It even covers the stuff that enterprises love, like TLS, RBAC, AD integration, and backups. Youll get the theory so that you know how it all fits together, and youll get commands and examples to show you how it all works in practice.

Most of the chapters in the technical stuff section are divided into three parts:

• The TLDR
• The Deep Dive
• The Commands

The TLDR gives you two or three paragraphs that you can use to explain the topic at the coffee machine. Theyre also a great way to remind yourself what something is about.

The Deep Dive is where we explain how everything works and go through the examples.

The Commands lists all the relevant commands in an easy to read list with brief reminders of what each one does.

I think youll love that format.

Docker is developing at a warp speed! As a result, the value of a book like this is inversely proportional to how old it is! In other words the older this book is, the less valuable it is.So I keep this book up-to-date!

Welcome to the new normal!

We no-longer live in a world where a 1-year old book is valuable. That makes my life as an author really hard. But its true!

Dont worry though, your investment in this book is safe!

If you buy the paperback copy from Amazon.com, you get the Kindle version for dirt-cheap as part of the Kindle MatchBook scheme! Kindle MatchBook is a new service that is only available on Amazon.com and is a bit buggy. If you cannot see how to get your Kindle version through MatchBook you need to contact Kindle support I cannot help you with this :-(

The Kindle and Leanpub versions get all updates at no extra cost!

Thats the best I can currently do!

Below is a list of versions:

• Version 5. This is the version of the book published on 6th February 2018. It includes ~200 new pages and covers all Docker Certified Associate exam topics. This version of the book got a new cover.
