Let's write a recipe that queries the list of users in our users data bag and creates a local user
for each item. You can use the search() method to perform the data bag query, just like you

user user_data [ "id" ] ddo
comment user_data [ "comment" ]
uid user_data [ "uid" ]
gid user_data [ "gid" ]
home user_data [ "home" ]
shell user_data [ "shell" ]
end end

end

The user statement within the search() block is a Chef resource. The user resource creates
a local user on the node. It takes the following attributes:
