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: "We just defined a name for our repo, ubi8-httpd, and we chose to link this repository to a GitHub repository push."

A block of code is set as follows:

[Unit]
Description=Podman API Socket
Documentation=man:podman-system-service(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:

$ podman ps

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

$ skopeo login -u admin -p p0dman4Dev0ps# --tls-verify=false localhost:5000
Login Succeeded!

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: "… and prints a crafted HTML page with the Hello World! message when it receives a GET / request."
