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: "We can create a new pipeline called calculator and, as pipeline script, put the code in a stage called Checkout."

A block of code is set as follows:

pipeline {
     agent any
     stages {
          stage("Checkout") {
               steps {
                    git url: 'https://github.com/leszko/calculator.git', branch: 'main'
               }
          }
     }
}

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

$ sudo apt-get update

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: "Select Gradle Project instead of Maven Project (you can choose Maven if you prefer it to Gradle)."
