# == Class: nova::scheduler
|
|
#
|
|
# Install and manage nova scheduler
|
|
#
|
|
# === Parameters:
|
|
#
|
|
# [*enabled*]
|
|
# (Optional) Whether to run the scheduler service
|
|
# Defaults to true
|
|
#
|
|
# [*manage_service*]
|
|
# (Optional) Whether to start/stop the service
|
|
# Defaults to true
|
|
#
|
|
# [*ensure_package*]
|
|
# (Optional) The state of the scheduler package
|
|
# Defaults to 'present'
|
|
#
|
|
# [*workers*]
|
|
# (Optional) The amount of scheduler workers.
|
|
# Defaults to $::os_workers
|
|
#
|
|
# [*scheduler_driver*]
|
|
# (Optional) Default driver to use for the scheduler
|
|
# Defaults to 'filter_scheduler'
|
|
#
|
|
# [*discover_hosts_in_cells_interval*]
|
|
# (Optional) This value controls how often (in seconds) the scheduler should
|
|
# attempt to discover new hosts that have been added to cells.
|
|
# Defaults to $::os_service_default
|
|
#
|
|
# [*query_placement_for_image_type_support*]
|
|
# (Optional) This setting causes the scheduler to ask placement only for
|
|
# compute hosts that support the ``disk_format`` of the image used in the
|
|
# request.
|
|
# Defaults to $::os_service_default
|
|
#
|
|
# [*limit_tenants_to_placement_aggregate*]
|
|
# (Optional) This setting 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.
|
|
# Defaults to $::os_service_default
|
|
#
|
|
# [*placement_aggregate_required_for_tenants*]
|
|
# (Optional) This setting controls if a tenant with no aggregate affinity
|
|
# will be allowed to schedule to any availalbe node when
|
|
# ``limit_tenants_to_placement_aggregate`` is set to True.
|
|
# 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.
|
|
# Defaults to $::os_service_default
|
|
#
|
|
# [*max_placement_results*]
|
|
# (Optional) This setting determines the maximum limit on results received
|
|
# from the placement service during a scheduling operation.
|
|
# Defaults to $::os_service_default
|
|
#
|
|
# [*enable_isolated_aggregate_filtering*]
|
|
# (Optional) This setting allows the scheduler to restrict hosts in aggregates
|
|
# based on matching required traits in the aggregate metadata and the instance
|
|
# flavor/image.
|
|
# Defaults to $::os_service_default
|
|
#
