  OpenStack containerized Nova Scheduler service

parameters:
  DockerNovaSchedulerImage:
    description: image
    type: string
  DockerNovaConfigImage:
    description: The container image to use for the nova config_volume
    type: string
  NovaSchedulerLoggingSource:
    type: json
    default:
      tag: openstack.nova.scheduler
      path: /var/log/containers/nova/nova-scheduler.log
  EndpointMap:
    default: {}
    description: Mapping of service endpoint -> protocol. Typically set
                 via parameter_defaults in the resource registry.
    type: json
  ServiceData:
    default: {}
    description: Dictionary packing service data
    type: json
  ServiceNetMap:
    default: {}
    description: Mapping of service_name -> network name. Typically set
                 via parameter_defaults in the resource registry.  This
                 mapping overrides those in ServiceNetMapDefaults.
    type: json
  DefaultPasswords:
    default: {}
    type: json
  RoleName:
    default: ''
    description: Role name on which the service is applied
    type: string
  RoleParameters:
    default: {}
    description: Parameters specific to the role
    type: json
  NovaSchedulerAvailableFilters:
    default: []
    description: List of scheduler available filters
    type: comma_delimited_list
  NovaSchedulerDefaultFilters:
    type: comma_delimited_list
    default: []
    description: >
      An array of filters used by Nova to filter a node.These filters will be
      applied in the order they are listed, so place your most restrictive
      filters first to make the filtering process more efficient.
  NovaSchedulerMaxAttempts:
    type: number
    default: 3
    description: >
     Maximum number of attempts the scheduler will make when deploying the
     instance. You should keep it greater or equal to the number of bare
     metal nodes you expect to deploy at once to work around potential race
     conditions when scheduling.
  MonitoringSubscriptionNovaScheduler:
    default: 'overcloud-nova-scheduler'
    type: string
  NovaSchedulerDiscoverHostsInCellsInterval:
    type: number
    default: -1
    description: >
      This value controls how often (in seconds) the scheduler should
      attempt to discover new hosts that have been added to cells.
      The default value of -1 disables the periodic task completely.
      It is recommended to set this parameter for deployments using Ironic.
  NovaSchedulerWorkers:
    default: 0
