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. Here is an example: "The definition uses HorizontalPodAutoscaler targeting the api Deployment. "
A block of code is set as follows:
1 sum(label_join( 2 rate( 3 container_cpu_usage_seconds_total{ 4 namespace!="kube-system", 5 pod_name!="" 6 }[5m] 7 )
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
1 sum(label_join( 2 rate( 3 container_cpu_usage_seconds_total{ 4 namespace!="kube-system", 5 pod_name!="" 6 }[5m] 7 )
Any command-line input or output is written as follows:
1 cd k8s-specs 2 3 git pull
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 Prometheus, and click the Import button."
