RunlistModifiers

This cookbook provides helpers to allow or disallow recipes from being loaded via the run list based on node attributes.

Repository:

https://github.com/heavywater/chef-runlist_modifiers

Attributes:

  • node[:restricted_recipes] = %w(users::sysadmins)
  • node[:allowed_recipes] = %w(sudo)

These are the two attributes available for modifying the run list. The behavior of each is similar but slightly different.

Restricted Recipes:

Restricted recipes are recipes which are not allowed to be run. This means that if a recipe in the run list depends on a recipe within the restricted recipes setting, neither recipe will be loaded.

Allowed Recipes:

Allowed recipes are recipes which are allowed to be loaded within the run list. This is the important distinction between the restricted and allowed recipes. The allowed recipes will remove any recipes execpt those specified from the initial run list. Any dependencies those recipes require will then be free to be loaded.

Combinations:

These attributes can be combined. This means that if a recipe in the allowed recipes depends on a recipe specified within the restricted recipes, it will not be loaded. The restricted recipes always have precedence.
