To get the most out of this book

You should have a basic understanding of the Linux, basic commands, tools like Git and a text editor like vi.

The book chapters contain both theory and hands-on exercises. We feel that the exercises help to reinforce the theory, but they are not required to understand each topic. If you want to do the exercises in the book, you will need to meet the requirement in the table below.

All exercises use Ubuntu, but most of them will work on other Linux installations. Chapter 10, Auditing using Falco, DevOps AI, and ECK has steps that are specific to Ubuntu and the exercise will likely fail to deploy correctly on other Linux installations.

Conventions used

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

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. For example; "The --name option will set the name of the cluster to cluster01, and --config tells the installer to use the cluster01-kind.yaml config file."

A block of code is set as follows:

apiVersion: apps/v1 
kind: Deployment 
metadata: 
  labels: 
    app: grafana 
  name: grafana 
  namespace: monitoring

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

apiVersion: apps/v1 
kind: Deployment 
metadata: 
  labels: 
    app: grafana 
  name: grafana 
  namespace: monitoring

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 on the screen, for example, in menus or dialog boxes, also appear in the text like this. For example: "Hit the Finish Login button at the bottom of the screen."
