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: "The OPENSTACK_KEYSTONE_DEFAULT_ROLE setting in the /etc/openstack-dashboard/local_settings.py file must also be modified before the dashboard can be used."
Any command-line input or output is written as follows:
# service nova-api restart# service nova-cert restart# service nova-consoleauth restart# service nova-scheduler restart# service nova-conductor restart# service nova-novncproxy restart
New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Looking at the following screenshot, the System Information panel provides the user with information about the environment, including Services and Compute Services."
Note
Warnings or important notes appear in a box like this.
