heat_template_version: wallaby description: > 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. Use parameter_merge_strategies to merge it with the defaults. 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 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: > (DEPRECATED) 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. NovaSchedulerQueryPlacementForAvailabilityZone: default: true description: > (DEPRECATED) 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. This parameter has no effect now. type: boolean conditions: nova_scheduler_workers_set: not: {equals : [{get_param: NovaSchedulerWorkers}, 0]} scheduler_default_filters: {not: {equals: [{get_param: NovaSchedulerDefaultFilters}, []]}} disabled_scheduler_enabled_filters: {equals: [{get_param: NovaSchedulerEnabledFilters}, []]} parameter_groups: - label: deprecated description: | The following parameters are deprecated and will be removed.
