Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “We can verify the image of our system and review its information by executing docker image inspect.”

A block of code is set as follows:

apiVersion: apps/v1
kind: ReplicaSet
metadata:
  name: replicated-webserver
spec:
  replicas: 3
  selector:
    matchLabels:
      application: webserver
  template:
     metadata:
         application: webserver
     spec:
       containers:
       - name: webserver-container
         image: docker.io/nginx:alpine

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

$ docker rm -f webserver webserver2

Bold: Indicates a new term, an important word, or words that you see on screen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “You can verify this by quickly accessing your Docker Desktop’s settings by navigating to Settings | Resources | WSL Integration.”
