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

Code in text: Indicates code words in text, table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and so on. Here is an example: “Let’s delete the old nginx-deployment that we created at the beginning of this chapter.”

A block of code is set as follows:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: kcna-pv-claim
spec:
  storageClassName: standard
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 3Gi

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