Defined in:

Overview

Class: nova::compute::provider

Managing Resource Providers Using Config File

Parameters

schema_version

(optional) Version ($Major, $minor) of the schema must successfully parse documents conforming to ($Major, *) Default to ‘1.0’

custom_inventories

Array of hashes describing the custom provider inventory added via the $config_file config file. Format: name/uuid - Resource providers to target can be identified by either UUID or name. In addition, the value $COMPUTE_NODE can be used in the UUID field to identify all nodes managed by the service. Exactly one of uuid or name is mandatory. If neither uuid or name is provided, the special uuid $COMPUTE_NODE gets set in the template

inventories - (Optional) Hash of custom provider inventories. ‘total’ is a mandatory property. Any other optional properties not populated will be given a default value by placement. If overriding a pre-existing provider values will not be preserved from the existing inventory.

traits - (Optional) Array of additional traits.

Example : [

{
  uuid => '$COMPUTE_NODE',
  inventories => {
    'CUSTOM_EXAMPLE_RESOURCE_CLASS' => {
      total            => '100',
      reserved         => '0',
      min_unit         => '1',
      max_unit         => '10',
      step_size        => '1',
      allocation_ratio => '1.0'
    },
    'CUSTOM_ANOTHER_EXAMPLE_RESOURCE_CLASS' => {
      total            => '100',
    },
  },
  traits => ['CUSTOM_P_STATE_ENABLED','CUSTOM_C_STATE_ENABLED'],
},
{
  name => 'EXAMPLE_RESOURCE_PROVIDER',
  inventories => {
    'CUSTOM_EXAMPLE_RESOURCE_CLASS' => {
      total            => '10000',
      reserved         => '100',
    },
  },
},

] Defaults to [].

config_location

(Optional) Location of YAML files containing resource provider configuration data. Defaults to /etc/nova/provider_config

config_file

(Optional) File name of the provider YAML file. Defaults to ‘provider.yaml’

Parameters:

  • schema_version (Any) (defaults to: '1.0')
  • custom_inventories (Any) (defaults to: [])
  • config_location (Any) (defaults to: '/etc/nova/provider_config')
  • config_file (Any) (defaults to: 'provider.yaml')
