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: "The Dockerfile is used to create the image when you run the docker build command." A block of code is set as follows:

{
"apiVersion": "v1",
"kind": "Pod",
"metadata":{
"name": ”rest_service”,
"labels": {
"name": "rest_service"
}
},
"spec": {
"containers": [{
"name": "rest_service",
"image": "rest_service",
"ports": [{"containerPort": 8080}],
}]
}
}

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

docker rm $(docker ps -a -q -f status=exited)

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: "Clicking the Skip For Now will take you to the the images list without logging into the Docker Hub."

Warnings or important notes appear in a box like this.
Tips and tricks appear like this.
