[chef] Re: Re: Re: Re: Re: accessing environment attributes in cookbooks

to be able to specify something like "#{node[: my_attr]}/some/directory" in an attribute file, you'll have to wait for chef 11.

you can do the same thing in your recipe until then:
node.default['my_cookbook']['cookbook_dir'] = "#{node[: my_attr]}/some/directory"

Mike and Daniel, thanks for the responses, and that makes sense about the attributes files. I did try logging from my cookbook's recipes/default.rb file, but my environment attribute was being evaluated as an empty string.

For example, with this in my environment's JSON file:

"default_attributes": {

  "my_attr": "/my/path"

},

Then if I put this in my attributes/default.rb file:

default['my_cookbook']['cookbook_dir'] = "#{node[: my_attr]}/some/directory"

And then log it like this in my recipes/default.rb:

Chef::Log.info(node[:my_attr])

Chef::Log.info(node['my_cookbook']['cookbook_dir'])

Then it logs:

INFO: /my/path

INFO: /some/directory

And not:

INFO: /my/path

INFO: /my/path/some/directory

Which is what I want. I would guess I'm just not using the proper syntax to define my attribute? But I've tried it with everything I can think of, and it's fine if I have to explicitly load the environment until Chef 11 :)

Thanks!
