- "This is a lookup plugin to provide access to chef data bags using the pychef package.
|
|
It interfaces with the chef server api using the same methods to find a knife or chef-client config file to load parameters from,
|
|
starting from either the given base path or the current working directory.
|
|
The lookup order mirrors the one from Chef, all folders in the base path are walked back looking for the following configuration
|
|
file in order : .chef/knife.rb, ~/.chef/knife.rb, /etc/chef/client.rb"
