OpenStack containerized Nova Scheduler service
parameters:
ContainerNovaSchedulerImage:
description: image
type: string
ContainerNovaConfigImage:
description: The container image to use for the nova config_volume
type: string
NovaSchedulerLoggingSource:
type: json
default:
tag: openstack.nova.scheduler
file: /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
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
NovaSchedulerEnabledFilters:
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
description: Number of workers for Nova Scheduler services.
type: number
NovaSchedulerQueryImageType:
type: boolean
default: true
description: >
This setting causes the scheduler to ask placement only for compute
hosts that support the disk_format of the image used in the request.
NovaSchedulerLimitTenantsToPlacementAggregate:
default: false
description: >
This value allows to have tenant isolation with placement. It ensures
hosts in tenant-isolated host aggregate and availability zones will
only be available to specific set of tenants.
type: boolean
NovaSchedulerPlacementAggregateRequiredForTenants:
default: false
description: >
This setting, when `NovaSchedulerLimitTenantsToPlacementAggregate` is true,
controls whether or not a tenant with no aggregate affinity will be allowed
to schedule to any available node.
If aggregates are used to limit some tenants but not all, then this should be
False. If all tenants should be confined via aggregate, then this should be True.
type: boolean
NovaSchedulerEnableIsolatedAggregateFiltering:
default: false
description: >
This setting allows the scheduler to restrict hosts in aggregates based on
matching required traits in the aggregate metadata and the instance flavor/image.
If an aggregate is configured with a property with key trait:$TRAIT_NAME and value
required, the instance flavor extra_specs and/or image metadata must also contain
trait:$TRAIT_NAME=required to be eligible to be scheduled to hosts in that aggregate.
type: boolean
NovaSchedulerQueryPlacementForAvailabilityZone:
default: false
description: >
This setting allows the scheduler to look up a host aggregate with metadata
key of availability zone set to the value provided by incoming request, and
request result from placement be limited to that aggregate.
type: boolean
NovaSchedulerQueryPlacementForRoutedNetworkAggregates:
default: false
description: >
This setting allows the scheduler to verify if the requested networks or port
are related to neutron routed network. This requires that the related
aggregates to be reported in placement, so only hosts within the asked
aggregates would be accepted.
type: boolean
NovaSchedulerHostSubsetSize:
default: 1
description: >
Size of subset of best hosts selected by scheduler.
type: number
NovaSchedulerShuffleBestSameWeighedHosts:
default: false
description: >
Enable spreading the instances between hosts with the same best weight.
type: boolean
# DEPRECATED: the following options are deprecated and are currently maintained
# for backwards compatibility. They will be removed in future release.
NovaSchedulerDefaultFilters:
type: comma_delimited_list
default: []
description: >

filters will be applied in the order they are listed, so place your most
restrictive filters first to make the filtering process more efficient.
