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: “To check the contents of a binary deb package, you can use the ar command.”

A block of code is set as follows:

spec: 
     replicas: 1 

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

$ sudo zypper search nmap

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

uid=1004(alex2) gid=1100(admin) groups=1100(admin),1200(developers),1300(devops),1400(managers)

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: “Navigate to Virtual Machines, select your instance, and click Size under Availability + Scale.”
