Module: ChefMetalDocker::Helpers::Container::Actions

Included in:
ChefMetalDocker::Helpers::Container
Defined in:
lib/chef_metal_docker/helpers/container/actions.rb

Overview

This is a collection of helper methods that are used to trigger actions in the LWRPs. By putting them in a separate file we can a) keep the LWRPs cleaner and b) unit test them!
