Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "If you want to stop a Docker container, use the docker stop command, supplying the name of the container you want to stop."

A block of code is set as follows:

{ 
  "firstName": "Chris", 
  "lastName": "Baxter", 
  "email": "[email protected]" 
}

Any command-line input or output is written as follows:

docker-build.sh

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Click the Docker whale icon in your system tray and select Preferences in the context menu that pops up."
