common_attrs cookbook
A cookbook which provides tools (libraries, custom resources) to help manage Attributes during Chef runs. This is especially useful when using PolicyFiles which require a workflow to replace the concept of Environments.
Be advised that this cookbook provides you with all of the necessary tools to shoot yourself in the foot ... repeatedly ... so much so that you may end up a bloody mess. When making use of any of the Custon Resources contained within, you should be sure to have a workflow in mind.
Requirements
This cookbook required Chef 12.7.0 or later.

Documentation
Comments will be found throughout the attribute, resource and library files
so that the documentation and code are more closely linked. What's found in
this Readme will be more of a high-level overview.
Custom Resources
common_environment
Resource which will load a data_bag_item
and apply it's contents onto the node
at either the environment
or role
precedence levels during compile time. The format of this file should be mostly identical to existing environment
files, with only the default_attributes and override_attributes keys being honored.
A recipe, common_attrs::environments
, also exists which will iterate through config[:common_attrs][:environments][:active][:prepend] and create a common_environment
for each of : node.environment, node.policy_group, node.policy_name.
The recipe will then loop through config[:common_attrs][:environments][:active][:custom], creating whatever further common_environment
resources are required.
common_namespae
Resource which will take a Hash-ish node attribute and merge it onto the node
at the environment
precedence level. This allows you to set attribute overrides for a given environment, policy_group or policy_file in a centralize location.
A recipe, common_attrs::namespaces
, also exists which will iterate through config[:common_attrs][:namespaces][:active][:prepend] and create a common_namespace
for each of : node.namespace, node.policy_group, node.policy_name.
The recipe will then loop through config[:common_attrs][:namespaces][:active][:custom], creating whatever further common_namespace
resources are required.
common_secrets
Resource which will load a data_bag_item
containing secrets into the node.run_state
if it has not already been created. This may then be used by other resources, such as common_secret
or directly within your recipes.
common_secret
Resource which will load a secret from common_secret
and apply it's value to a node
attribute at compile time. In addition, the attribute path will be registered to node[:common_attrs][:obfuscated]
so that it's value is wiped prior to reporting to Chef server.
Recipes
- default: Load allofthethings
- environments: Load
common_environment
from attributes - namespaces: Load
common_namespace
from attributes - secrets: Load
common_secret
from attributes - obfuscated: Register a Chef Event handler to obfuscate attributes at the end of the converge phase.
Library Methods
This cookbook provides a number of helper methods and injects a few of them by monkey patching DataBagItem, Node::Atributes and Resource. When doing this, special care is taken to ensure that the method names are namespaced so as to minimize future WTF moments.
Documentation on each of these may be found within the library files.
- Hash.dig
- Hash.common_assign_at
- Resource.common_properties
- DataBagItem.to_common_data
- DataBagItem.to_common_namespace
- Attribute.to_common_data
- Attribute.to_common_namespace
- Comon::Delegator::ObfuscatedType
Attribute Precedence
Given that we're dealing with Attributes, special care needs to be taken to ensure that we don't get lost in the myriad of different precedence levels.
