In-Depth Information
With your handy programmer's text editor, edit the file
files/default/motd
you just created in
your
motd
cookbook. We think all messages are more effective when spoken by a friendly
warning cow, so we added a bit of ASCII art to our file, as shown in
Example 7-2
.

Introducing the Cookbook_file Resource
We'll use Chef to help us more easily determine that we are running on a guest virtual ma-
chine node by writing some automation to change the Linux
message of the day
. On Linux,
the message of the day is displayed when a user logs in. The message of the day is used by
Linux administrators to communicate with users. You can change the message of the day by
editing the file
/etc/motd
. When a user successfully logs in, the contents of the
/etc/motd
file
will be displayed as the message of the day.
chef cookbook generate
created a
recipes/default.rb
file for you. By convention, this is
the default location for your Chef code. All recipe
.rb
files containing Chef code are expec-
ted to be in the
recipes/
subdirectory of a cookbook.
At the moment,
recipes/default.rb
doesn't have very much in it, just some comments:
