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: "Create the .kube directory in your home directory."

A block of code is set as follows:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: postgresql
  labels:
    app: postgresql

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

spec:
  replicas: 1
  selector:
    matchLabels:
      app: postgresql

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

$ kubectl version –client --short
Client Version: v1.18.1

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "We assigned Labels and Annotations to the node, and there are no Roles or Taints set."
