# == Class: tripleo::profile::base::swift::ringbuilder
#
# Swift ringbuilder profile for tripleo
#
# === Parameters
#
#  [*replicas*]
#    replicas
#
#  [*build_ring*] = true,
#   (Optional) Whether to build the ring
#   Defaults to true
#
#  [*devices*]
#   (Optional) DEPRECATED The swift devices
#   Should pass raw_disk_prefix, raw_disks and swift_storage_node_ips instead
#   Defaults to ''
#
#  [*step*]
#   (Optional) The current step in deployment. See tripleo-heat-templates
#   for more details.
#   Defaults to hiera('step')
#
#  [*swift_zones*]
#   (Optional) The swift zones
#   Defaults to 1
#
#  [*raw_disk_prefix*]
#   (Optional) Disk prefix used to create devices list
#   Defaults to 'r1z1-'
#
#  [*raw_disks*]
#   (Optional) list of raw disks in format
#   [':%PORT%/device1', ':%PORT%/device2']
#   Combined with raw_disk_prefix and swift_storage_node_ips
#   to create devices list
#   Defaults to an empty list
#
#  [*swift_storage_node_ips*]
#  (Optional) list of ip addresses for nodes running swift_storage service
#  Defaults to hiera('swift_storage_node_ips') or an empty list
#
#  [*part_power*]
#  (Optional) The total number of partitions that should exist in the ring.
#  This is expressed as a power of 2.
#  Defaults to undef
#
#  [*min_part_hours*]
#  Minimum amount of time before partitions can be moved.
#  Defaults to undef
#
# [*swift_ring_get_tempurl*]
# GET tempurl to fetch Swift rings from
#
# [*swift_ring_put_tempurl*]
# PUT tempurl to upload Swift rings to
#
# [*skip_consistency_check*]
# If set to true, skip the recon check to ensure rings are identical on all
# nodes. Defaults to false
#
