OpenStack Nova Scheduler service configured with Puppet
parameters:
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
EndpointMap:
default: {}
description: Mapping of service endpoint -> protocol. Typically set
via parameter_defaults in the resource registry.
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
NovaSchedulerLoggingSource:
type: json
default:
tag: openstack.nova.scheduler
path: /var/log/nova/nova-scheduler.log
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
description: Number of workers for Nova Scheduler services.
