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"

Warnings or important notes appear like this.

Tips and tricks appear like this.
