This adds defined anchor points for external modules to hook into the software install, config and service dependency chain. This allows external modules to manage software installation (virtualenv, containers, etc) and service management (pacemaker) without needing rely on resources that may change or be renamed.

# Used to configure nodes that are responsible for managing swift rings.
|
|
# Rings are used to make decicions about how to map objects in the cluster
|
|
#
|
|
# Specifies the following relationship:
|
|
# Rings should be created before any devices are added to them
|
|
# Rings should be rebalanced if anything changes
|
|
# == Parameters
|
|
# [*part_power*] The total number of partitions that should exist in the ring.
|
|
# This is expressed as a power of 2.
|
|
# [*replicas*] Numer of replicas that should be maintained of each stored object.
|
|
# [*min_part_hours*] Minimum amount of time before partitions can be moved.
