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: "The final component to identify is apiGroups. This is an additional area of inconsistency from the URL model."

A block of code is set as follows:

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  name: cluster-pod-and-pod-logs-reader
rules:
- apiGroups: [""]
  resources: ["pods", "pods/log"]
  verbs: ["get", "list"]

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

  - hostPath:
      path: /usr/share/ca-certificates
      type: DirectoryOrCreate
    name: usr-share-ca-certificates
  - hostPath:
      path: /var/log/k8s
      type: DirectoryOrCreate
    name: var-log-k8s
  - hostPath:
      path: /etc/kubernetes/audit
      type: DirectoryOrCreate
    name: etc-kubernetes-audit

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

PS C:\Users\mlb> kubectl create ns not-going-to-work namespace/not-going-to-work created

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: "Hit the Finish Login button at the bottom of the screen."
