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: "First, we will create a directory for our PKI and generate the CA's private key in a file called ca-key.pem."

A block of code is set as follows:

{
  "tlsverify": true,
  "tlscacert": "/etc/docker/ca.pem",
  "tlskey": "/etc/docker/server-key.pem",
  "tlscert": "/etc/docker/server.pem"
}

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

dockerhost$ systemctl daemon-reload
dockerhost$ systemctl restart docker.service

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: " In the form field labeled Name, set the value to Unicorn Capacity."
