class Chef::CookbookCollection
Chef::CookbookCollection
¶ ↑
This class is the consistent interface for a node to obtain its cookbooks by name.
This class is basically a glorified Hash, but since there are several ways this cookbook information is collected, (e.g. CookbookLoader
for solo, hash of auto-vivified Cookbook
objects for lazily-loaded remote cookbooks), it gets transformed into this.

# File lib/chef/cookbook/cookbook_collection.rb, line 36 def initialize(cookbook_versions = {}) super() do |hash, key| raise Chef::Exceptions::CookbookNotFound, "Cookbook #{key} not found. " << "If you're loading #{key} from another cookbook, make sure you configure the dependency in your metadata" end cookbook_versions.each { |cookbook_name, cookbook_version| self[cookbook_name] = cookbook_version } end
The input is a mapping of cookbook name to CookbookVersion
objects. We simply extract them

Validates that the cookbook metadata allows it to run on this instance.
Currently checks chef_version and ohai_version in the cookbook metadata against the running Chef::VERSION and Ohai::VERSION.
@raise [Chef::Exceptions::CookbookChefVersionMismatch] if the Chef::VERSION fails validation @raise [Chef::Exceptions::CookbookOhaiVersionMismatch] if the Ohai::VERSION fails validation
