TIP
Note that our
.kitchen.yml
file includes only a reference to the
default
recipe in its run
list. We never intend for external consumers of our cookbook to refer to this
message

message
recipe to organize our code, and it is assumed
that
include_recipe
will be used inside the
default
recipe to include any other neces-
sary code:
...
run_list:
- recipe[motd-attributes::default]
...
Some Chef coders use the convention of putting an underscore prefix (“_”) in the name of
recipes that are “private”—recipes used merely to organize Chef code into smaller, more
understandable chunks. They name the recipe file
"_message.rb"
to make this intent
more clear in the cookbook file structure.
Also, you need to add an
include_recipe
statement to your
default.rb
. The
in-
clude_recipe
statement ensures that the
message.rb
file gets processed during the Chef run.
Otherwise, only the recipe file
default.rb
will be evaluated when the run list is
