One way is to override it from the environments/some-env.rb file.

But I think to look its values later, I'll have to re-map opening individual env files.

It would be better if I could just add it in the roles file per env like env_run_list.

Is this already in chef or any plugins?

The way we deal with it is to create a cookbook/recipe per role.  So we would introduce a cookbook named "mybiz-ftpserver". Then have it do any of the environment specific logic before including the relevant recipes. Something like;

file: mybiz-ftpserver/recipes/default.rb

--------------------------------------------------------

if node.environment == 'production'

  node.override['vsftpd']['chroot_users'] = ["ftpuser"]

else 

  node.override['vsftpd']['chroot_users'] = ["other_ftpuser"]

end

include_recipe 'vsftpd::default'

--------------------------------------------------------

And then the role would look something like

roles/ftpserver.rb

--------------------------------------------------------

name "ftpserver"

description "ftpserver"

run_list('mybiz-ftpserver')

--------------------------------------------------------

That way all the logic you want for environment specific customisation is explicit in a cookbook and relatively easy to understand.

HTH,
