Basic Attribute Priority
Now let's experiment with the basics of attribute priorities by trying to reset values set else-
where. As shown in
Example 8-7
,
modify the
recipe/default.rb
so that it tries to reset the
value of a higher priority automatic attribute set by
ohai
, and a lower priority attribute
defined in the attribute file.
Example 8-7. chefdk/motd-attributes/recipes/default.rb
node
.
default
[
'ipaddress'
] =
'1.1.1.1'
node
.
default
[
'motd-attributes'
][
'company'
] =
'My Company'
node
.
default
[
'motd-attributes'
][
'message'
] =
"It's a wonderful day today!"
template
'/etc/motd'
ddo
source
'motd.erb'
mode
"0644"
end
end
Perform a Chef run and check to see the resulting values:
