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: “Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system.”
A block of code is set as follows:
>>> hashB = int(md5(SEPARATOR.join(targetB).encode("utf-8")).hexdigest(), 16)
>>> hashB
139861250730998106692854767707986305935
>>> print(f"{targetA} % {MOD} = ", hashA % MOD)
['app=nginx', 'instance=node2'] % 2 = 0
>>> print(f"{targetB} % {MOD} = ", hashB % MOD)
['app=nginx', 'instance=node23'] % 2 = 1 When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
alerting: alert_relabel_configs: - regex: prometheus_replica action: labeldrop
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: “Select System info from the Administration panel.”
