Docker Deep Dive

By: Nigel Poulton

Overview of this book

Most applications, even the funky cloud-native microservices ones, need high-performance, production-grade infrastructure to run on. Having impeccable knowledge of Docker will help you to thrive in the modern cloud-first world. With this book, you’ll gain the skills you need to work with Docker and its containers. The book begins with an introduction to containers and explains its functionality and application in the real world. You’ll then get an overview of VMware, Kubernetes, and Docker and learn to install Docker on Windows, Mac, and Linux. Once you’ve understood the Ops and Dev perspective of Docker, you’ll be able to see the big picture and understand what Docker exactly does. The book then turns its attention to the more technical aspects, guiding your through practical exercises covering Docker engine, Docker images, and Docker containers. You’ll learn techniques for containerizing an app, deploying apps with Docker Compose, and managing cloud-native applications with Swarm. You’ll also build Docker networks and Docker overlay networks and handle applications that write persistent data. Finally, you’ll deploy apps with Docker stacks and secure your Docker environment. By the end of this book, you’ll be well-versed in Docker and containers and have developed the skills to create, deploy, and run applications on the cloud.

How the book is organized

I’ve divided the book into two sections:

  1. The big picture stuff
  2. The technical stuff

The big picture stuff section covers things like:

  • What is Docker
  • Why do we have containers
  • What do things like “cloud-native” and “microservices” mean…

It’s 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 where you’ll 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 cover’s the stuff that enterprises love — TLS, image signing, high-availability, backups, and more.

Each chapter covers theory and includes plenty of commands and examples.

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...
