ABOUT THIS BOOK
xviii
Code conventions and downloads
This book is about a multi-purpose tool, and so there is very little “code” included
in the book. In its place are hundreds of shell commands and configuration files.
These are typically provided in
POSIX-compliant syntax. Notes for Windows users
are provided where Docker exposes some Windows-specific features. Care was
taken to break up commands into multiple lines in order to improve readability
or clarify annotations. Referenced repositories are available on Docker Hub
(https://hub.docker.com/u/dockerinaction/) with sources hosted on GitHub
(https://github.com/dockerinaction). No prior knowledge of Docker Hub or
GitHub is required to run the examples.
This book uses several open source projects to both demonstrate various features
of Docker and help the reader shift software-management paradigms. No single soft-
ware “stack” or family is highlighted other than Docker itself. Working through the
examples, the reader will use tools such as WordPress, Elasticsearch, Postgres, shell
scripts, Netcat, Flask, JavaScript,
NGINX, and Java. The sole commonality is a depen-
dency on the Linux kernel.
