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/X handles. Here is an example: “The directory path is nested within the chart, and the use of this directory called crds/ allows Helm to pause while the CRDs are added to a cluster before continuing with the chart execution.”

A block of code is set as follows:

apiVersion: apiextensions.k8s.io/v1beta1
kind: CustomResourceDefinition
metadata:
  name: crontabs.stable.example.com
spec:
  group: stable.example.com
  version: v1
  scope: Namespaced
  names:
    plural: crontabs
    singular: crontab
    kind: CronTab
    shortNames:
    - ct

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

$ kubectl label nodes platform-worker2 reserved=reserved
node/platform-worker2 labeled

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “These platform logs should also, as much as possible, be clear of any Personally Identifiable Information (PII).”
