This cookbook provides a library that allows you to set a whitelist of node attributes that should be saved on the server. All of the attributes are still available throughout the chef run, but only those specifically listed will be saved to the server.


Chef 0.9.0+

Requires chef-client and a Chef Server - this cookbook doesn't make sense, nor work, with chef-solo.

Works on any platform.


node[:whitelist] provides a map of node attributes to store. The defaults are provided by this cookbook, and the map is:

node.default[:whitelist] = {
  "domain" => true,
  "fqdn" => true,
  "hostname" => true,
  "ipaddress" => true,
  "macaddress" => true,
  "platform" => true,
  "platform_version" => true,
  "kernel" => {
    "machine" => true,
    "name" => true,
    "os" => true,
    "release" => true,
    "version" => true

This cookbook honors the fact that attributes are set at different precedence levels.


Upload the cookbook, and make sure that it is included as a dependency in another cookbooks metadata, or that the recipe (which does nothing) is included in the role.

Whenever is called, such as at the end of the run, the whitelist will be applied.
