Puppet Class: nova::cell_v2::map_instances

Defined in:

Overview

Class: nova::cell_v2::map_instances

Resource to run the map_instances action for cell v2

Parameters

cell_uuid

(String) Cell UUID to map unmigrated instances to. It is recommended to use this rather than cell name. Either cell_uuid or cell_name must be provided. Defaults to undef.

cell_name

(String) Cell name to map the unmigrated instances to. We will attempt to extract the cell uuid using the name as the command requires a cell uuid. NOTE: This will not work if you have multiple cells with the same name. Defaults to undef.

extra_params

(String) Extra parameters to pass to the nova-manage commands. Defaults to ”.

Parameters:

  • cell_uuid (Any) (defaults to: undef)
  • cell_name (Any) (defaults to: undef)
  • extra_params (Any) (defaults to: '')
