Chef cookbook - copy complete directory from files/default location in cookbook to a new location

I am a beginner to Chef. Can any one please advise if there is a way to copy a directory inside cookbook's files/default directory to a different location.

E.g. I have a directory structure with files a.txt and b.txt in files/ directory as follows cookbook_name/files/default/folder-name/[a.txt,b.txt]. I want them both files to be a location /home/user/work/somelocation/folder-name/[a.txt,b.txt]

I have tried cookbook_file resource as follows:

cookbook_file '/home/user/work/somelocation/' do
  source ['folder-name']
  mode "0644"
  action :create
end

and

cookbook_file '/home/user/work/somelocation/' do
  source ['folder-name/a.txt',''folder-name/b.txt'']
  mode "0644"
  action :create
end

I am aware of other means of copying files between arbitrary directories by looping through, but I am keen to know if there is more elegant way to handle directories akin to how cookbook_file handles files from standard folders inside cookbook's files/default directory.

I'm facing a similar problem and ATM the near thing to a solution I have is that in a recipe run_context.cookbook_collection[<cookbook-name>].file_filenames is an array with the complete path in destination for all the files under <cookbook>/files

for example in my config for a directory like this:

files/
  default/
     foo.txt
     bar.txt
     baz/foo.txt

It returns a directory like

[
  "/opt/kitchen/cache/cookbooks/cookbook/files/default/foo.txt",
  "/opt/kitchen/cache/cookbooks/cookbook/files/default/bar.txt",
  "/opt/kitchen/cache/cookbooks/cookbook/files/default/baz/foo.txt"
]

But this is not very useful to me

remote_directory allows you to copy a whole directory to a location of your choice. For example:

remote_directory "/etc/some_target_directory" do
  source 'local_directory' # <-- this is your directory in files/default/local_directory
  files_owner 'root'                                                                 
  files_group 'root'
  files_mode '0750'
  action :create
  recursive true                                                                      
end

There is AFAIK no "good/clean" way to copy all files that are contained in a cookbook.

In order to create multiple files, you can apply simple ruby logic to loop over these files:

['a.txt', 'b.txt'].each do |file|
  cookbook_file "/home/user/work/somelocation/#{file}" do
    source "folder-name/#{file}"
    mode "0644"
  end
end

This will create multiple cookbook_file resources (what @jamesgaddum is talking of).

P.S. the default/ part in files/default/ is optional since couple of Chef versions.

Unlikely as cookbook_file uses a checksum to compare the existing and new file, so requires a unique cookbook_file resource for each.
