In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.
Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: " By default, Marathon logs to stdout and syslog."
A block of code is set as follows:
cat <<EOF > /etc/systemd/system/traefik.service

Wants=network-online.target
After=network.target network-online.target
[Service]
Restart=on-failure
ExecStart=/usr/bin/traefik
[Install]
WantedBy=multi-user.target
EOF
Any command-line input or output is written as follows:
curl -k https://localhost:8443/ping
