# File 'lib/chef/provisioning/load_balancer_spec.rb', line 56

def driver_url
  location ? location['driver_url'] : nil
end

#idObject

Globally unique identifier for this machine. Does not depend on the machine's location or existence.

# File 'lib/chef/provisioning/load_balancer_spec.rb', line 24

def id
  raise "id unimplemented"
end

#locationObject

Location of this machine. This should be a freeform hash, with enough information for the driver to look it up and create a Machine object to access it.

This MUST include a 'driver_url' attribute with the driver's URL in it.

chef-provisioning will do its darnedest to not lose this information.
