There are several text conventions used throughout this book.

CodeInText: Indicates code words in a text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Optionally, you can configure a separate disk to mount /var/lib/docker and restart Docker."

A block of code is as follows:

apiVersion: authentication.istio.io/v1alpha1
kind: Policy
metadata:
  name: SVC-A-mTLS-disable
  namespace: ns1
spec:
  targets:
  - name: Service-A
  peers:
  - mtls:
      mode: DISABLE

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

  peers:
  - mtls:
      mode: DISABLE

Any command-line input or output shows as follows:

$ kubectl get pods
$ istioctl proxy

Bold: Indicates a new term, an important word, or words that you see on screen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "On the left-hand menu under Workloads, click Pods."
