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. 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:

 docker service create \
     --name util \
     --network monitor \
     --mode global \
     alpine sleep 100000000

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

docker service create \
    --name util \
    --network monitor \
    --mode global \
    alpine sleep 100000000

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

docker container exec -it $ID \
 curl node-exporter:9100/metrics

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: " Depending on the view, you should see three values in Console or three lines in
the Graph tab"
