# Overview
# ========
#
# This file contains the configuration for the OpenStack Ansible Deployment
# (OSAD) Object Storage (swift) service. Only enable these options for
# deployments that contain the Object Storage service. For more information on
# these options, see the documentation at
#
# http://docs.openstack.org/developer/swift/index.html
#
# You can customize the options in this file and copy it to
# /etc/openstack_deploy/conf.d/swift.yml or create a new
# file containing only necessary options for your environment
# before deployment.
#
# OSAD implements PyYAML to parse YAML files and therefore supports structure
# and formatting options that augment traditional YAML. For example, aliases
# or references. For more information on PyYAML, see the documentation at
#
# http://pyyaml.org/wiki/PyYAMLDocumentation
#
# Configuration reference
# =======================
#
# Level: global_overrides (required)
# Contains global options that require customization for a deployment. For
# example, the ring stricture. This level also provides a mechanism to
# override other options defined in the playbook structure.
#
# Level: swift (required)
# Contains options for swift.
#
# Option: storage_network (required, string)
# Name of the storage network bridge on target hosts. Typically
# 'br-storage'.
#
# Option: repl_network (optional, string)
# Name of the replication network bridge on target hosts. Typically
# 'br-repl'. Defaults to the value of the 'storage_network' option.
#
# Option: part_power (required, integer)
# Partition power. Applies to all rings unless overridden at the 'account'
# or 'container' levels or within a policy in the 'storage_policies' level.
# Immutable without rebuilding the rings.
#
# Option: repl_number (optional, integer)
# Number of replicas for each partition. Applies to all rings unless
# overridden at the 'account' or 'container' levels or within a policy
# in the 'storage_policies' level. Defaults to 3.
#
# Option: min_part_hours (optional, integer)
# Minimum time in hours between multiple moves of the same partition.
# Applies to all rings unless overridden at the 'account' or 'container'
# levels or within a policy in the 'storage_policies' level. Defaults
# to 1.
#
# Option: region (optional, integer)
# Region of a disk. Applies to all disks in all storage hosts unless
# overridden deeper in the structure. Defaults to 1.
#
# Option: zone (optional, integer)
# Zone of a disk. Applies to all disks in all storage hosts unless
# overridden deeper in the structure. Defaults to 0.
#
# Option: weight (optional, integer)
# Weight of a disk. Applies to all disks in all storage hosts unless
# overridden deeper in the structure. Defaults to 100.
#
# Example:
#
# Define a typical deployment:
#
# - Storage network that uses the 'br-storage' bridge. Proxy containers
# typically use the 'storage' IP address pool. However, storage hosts
# use bare metal and require manual configuration of the 'br-storage'
# bridge on each host.
# - Replication network that uses the 'br-repl' bridge. Only storage hosts
# contain this network. Storage hosts use bare metal and require manual
# configuration of the bridge on each host.
# - Ring configuration with partition power of 8, three replicas of each
# file, and minimum 1 hour between migrations of the same partition. All
# rings use region 1 and zone 0. All disks include a weight of 100.
#
# swift:

# replication_network: 'br-repl'
# part_power: 8
# repl_number: 3
# min_part_hours: 1
# region: 1
# zone: 0
# weight: 100
#
# Note: Most typical deployments override the 'zone' option in the
# 'swift_vars' level to use a unique zone for each storage host.
#
# Option: mount_point (required, string)
# Top-level directory for mount points of disks. Defaults to /mnt.
# Applies to all hosts unless overridden deeper in the structure.
#
# Level: drives (required)

# storage hosts:
#
# mount_point: /mnt

# policies.

# Defines the number of object parity fragments. Required for erasure
# coding policies.
#
# Option: ec_object_segment_size (conditionally required, integer)
# Defines the size of object segments in bytes. Swift sends incoming
# objects to an erasure coding policy in segments of this size.
# Required for erasure coding policies.
#
# Option: default (conditionally required, boolean)
# Defines the default policy. One policy must include this option
# with a 'True' value.
#
# Option: deprecated (optional, boolean)
# Defines a deprecated policy.
#
# Note: The following levels and options override any values higher
# in the structure and generally apply to advanced deployments.
