# Overview
# ========
#
# This file contains the configuration for the OpenStack Ansible Deployment
# (OSA) 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.
#
# OSA 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.
#
# Option: reclaim_age (optional, integer, default 604800)
# The amount of time in seconds before items, such as tombstones are
# reclaimed, default is 604800 (7 Days).
#
# Option: statsd_host (optional, string)
# Swift supports statsd metrics, this option sets the statsd host that will
# receive statsd metrics. Specifying this here will apply to all hosts in
# a cluster. It can be overridden or specified deeper in the structure if you
# want to only catch statsd metrics on certain hosts.
#
# Option: statsd_port (optional, integer, default 8125)
# Statsd port, requires statsd_host set.
#
# Option: statsd_metric_prefix (optional, string, default ansible_host)
# Specify a prefix that will be prepended to all metrics, this should be specified
# deeper in the configuration so different host metrics can be separated.
#
# The following statsd related options are a little more complicated and are
# used to tune how many samples are sent to statsd. If you need to tweak these
# settings then first read: https://docs.openstack.org/swift/latest/admin_guide.html
#
# Option: statsd_default_sample_rate (optional, float, default 1.0)
# Option: statsd_sample_rate_factor (optional, float, default 1.0)
#
# 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.

# replication_network: 'br-repl'
# part_power: 8
# repl_number: 3

# region: 1
# zone: 0
# weight: 100
# statsd_host: statsd.example.lan

# Note: Most typical deployments override the 'zone' option in the

# 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.

# --------
#
# Level: swift-proxy_hosts (required)
# List of target hosts on which to deploy the swift proxy service. Recommend
# three minimum target hosts for these services. Typically contains the same
# target hosts as the 'shared-infra_hosts' level in complete OpenStack
# deployments.
#
# Level: <value> (optional, string)
# Name of a proxy host.
#
# Option: ip (required, string)
# IP address of this target host, typically the IP address assigned to
# the management bridge.
#
# Level: container_vars (optional)
# Contains options for this target host.
#
# Level: swift_proxy_vars (optional)
# Contains swift proxy options for this target host. Typical deployments
# use this level to define read/write affinity settings for proxy hosts.
#
# Option: read_affinity (optional, string)
# Specify which region/zones the proxy server should prefer for reads
# from the account, container and object services.
# E.g. read_affinity: "r1=100" this would prefer region 1
# read_affinity: "r1z1=100, r1=200" this would prefer region 1 zone 1
# if that is unavailable region 1, otherwise any available region/zone.
# Lower number is higher priority. When this option is specified the
# sorting_method is set to 'affinity' automatically.
#
# Option: write_affinity (optional, string)
# Specify which region to prefer when object PUT requests are made.
# E.g. write_affinity: "r1" - favours region 1 for object PUTs
#
# Option: write_affinity_node_count (optional, string)
# Specify how many copies to prioritise in specified region on
# handoff nodes for Object PUT requests.
# Requires "write_affinity" to be set in order to be useful.
# This is a short term way to ensure replication happens locally,
# Swift's eventual consistency will ensure proper distribution over
# time.
# e.g. write_affinity_node_count: "2 * replicas" - this would try to
# store Object PUT replicas on up to 6 disks in region 1 assuming
# replicas is 3, and write_affinity = r1
#
# Option: statsd_host (optional, string)
# Swift supports statsd metrics, this option sets the statsd host that will
# receive statsd metrics.
#
# Option: statsd_port (optional, integer, default 8125)
# Statsd port, requires statsd_host set.
#
# Option: statsd_metric_prefix (optional, string, default ansible_host)
# Specify a prefix that will be prepended to all metrics on this host.
#
# The following statsd related options are a little more complicated and are
# used to tune how many samples are sent to statsd. If you need to tweak these
# settings then first read: https://docs.openstack.org/swift/latest/admin_guide.html
#
# Option: statsd_default_sample_rate (optional, float, default 1.0)
# Option: statsd_sample_rate_factor (optional, float, default 1.0)
#
# Example:
#
# Define three swift proxy hosts:
#
# swift-proxy_hosts:
#
# infra1:
# ip: 172.29.236.101
# container_vars:
# swift_proxy_vars:
# read_affinity: "r1=100"
