+======================================
+ Ceph Object Gateway Config Reference
+======================================
+
+The following settings may added to the Ceph configuration file (i.e., usually
+``ceph.conf``) under the ``[client.radosgw.{instance-name}]`` section. The
+settings may contain default values. If you do not specify each setting in the
+Ceph configuration file, the default value will be set automatically.
+
+Configuration variables set under the ``[client.radosgw.{instance-name}]``
+section will not apply to rgw or radosgw-admin commands without an instance-name
+specified in the command. Thus variables meant to be applied to all RGW
+instances or all radosgw-admin commands can be put into the ``[global]`` or the
+``[client]`` section to avoid specifying instance-name.
+
+``rgw frontends``

+Multisite Settings
+==================
+
+.. versionadded:: Jewel
+
+You may include the following settings in your Ceph configuration
+file under each ``[client.radosgw.{instance-name}]`` instance.
+
+
+``rgw zone``
+
+:Description: The name of the zone for the gateway instance. If no zone is
+ set, a cluster-wide default can be configured with the command
+ ``radosgw-admin zone default``.
+:Type: String
+:Default: None
+
+
+``rgw zonegroup``
+
+:Description: The name of the zonegroup for the gateway instance. If no
+ zonegroup is set, a cluster-wide default can be configured with
+ the command ``radosgw-admin zonegroup default``.
+:Type: String
+:Default: None
+
+
+``rgw realm``
+
+:Description: The name of the realm for the gateway instance. If no realm is
+ set, a cluster-wide default can be configured with the command
+ ``radosgw-admin realm default``.
+:Type: String
+:Default: None
+
+
+``rgw run sync thread``
+
+:Description: If there are other zones in the realm to sync from, spawn threads
+ to handle the sync of data and metadata.
+:Type: Boolean
+:Default: ``true``
+
+
+``rgw data log window``
+
+:Description: The data log entries window in seconds.
+:Type: Integer
+:Default: ``30``
+
+
+``rgw data log changes size``
+
+:Description: The number of in-memory entries to hold for the data changes log.
+:Type: Integer
+:Default: ``1000``
+
+
+``rgw data log obj prefix``
+
+:Description: The object name prefix for the data log.
+:Type: String
+:Default: ``data_log``
+
+
+``rgw data log num shards``
+
+:Description: The number of shards (objects) on which to keep the
+ data changes log.
+
+:Type: Integer
+:Default: ``128``
+
+
+``rgw md log max shards``
+
+:Description: The maximum number of shards for the metadata log.
+:Type: Integer
+:Default: ``64``
+
+.. important:: The values of ``rgw data log num shards`` and
+ ``rgw md log max shards`` should not be changed after sync has
+ started.
+
+
+Swift Settings
+==============
+
+``rgw enforce swift acls``
+
+:Description: Enforces the Swift Access Control List (ACL) settings.
+:Type: Boolean
+:Default: ``true``
+
+
+``rgw swift token expiration``
+
+:Description: The time in seconds for expiring a Swift token.
+:Type: Integer
+:Default: ``24 * 3600``
+
+
+``rgw swift url``
+
+:Description: The URL for the Ceph Object Gateway Swift API.
+:Type: String
+:Default: None
+
+
+``rgw swift url prefix``
+
+:Description: The URL prefix for the Swift API, to distinguish it from
+ the S3 API endpoint. The default is ``swift``, which
+ makes the Swift API available at the URL
+ ``http://host:port/swift/v1`` (or
+ ``http://host:port/swift/v1/AUTH_%(tenant_id)s`` if
+ ``rgw swift account in url`` is enabled).
+
+ For compatibility, setting this configuration variable
+ to the empty string causes the default ``swift`` to be
+ used; if you do want an empty prefix, set this option to
+ ``/``.
+
+ .. warning:: If you set this option to ``/``, you must
+ disable the S3 API by modifying ``rgw
+ enable apis`` to exclude ``s3``. It is not
+ possible to operate radosgw with ``rgw
+ swift url prefix = /`` and simultaneously
+ support both the S3 and Swift APIs. If you
+ do need to support both APIs without
+ prefixes, deploy multiple radosgw instances
+ to listen on different hosts (or ports)
+ instead, enabling some for S3 and some for
+ Swift.
+:Default: ``swift``
+:Example: "/swift-testing"
+
+
+``rgw swift auth url``
+
+:Description: Default URL for verifying v1 auth tokens (if not using internal
+ Swift auth).

+
+``rgw swift auth entry``
+
+:Description: The entry point for a Swift auth URL.
+:Type: String
+:Default: ``auth``
+
+
+``rgw swift account in url``
+
+:Description: Whether or not the Swift account name should be included
+ in the Swift API URL.
+
+ If set to ``false`` (the default), then the Swift API
+ will listen on a URL formed like
+ ``http://host:port/<rgw_swift_url_prefix>/v1``, and the
+ account name (commonly a Keystone project UUID if
+ radosgw is configured with `Keystone integration
+ <../keystone>`_) will be inferred from request
+ headers.
+
+ If set to ``true``, the Swift API URL will be
+ ``http://host:port/<rgw_swift_url_prefix>/v1/AUTH_<account_name>``
+ (or
+ ``http://host:port/<rgw_swift_url_prefix>/v1/AUTH_<keystone_project_id>``)
+ instead, and the Keystone ``object-store`` endpoint must
+ accordingly be configured to include the
+ ``AUTH_%(tenant_id)s`` suffix.
+
+ You **must** set this option to ``true`` (and update the
+ Keystone service catalog) if you want radosgw to support
+ publicly-readable containers and `temporary URLs
+ <../swift/tempurl>`_.
+:Type: Boolean
+:Default: ``false``
+
+
+``rgw swift versioning enabled``
+
+:Description: Enables the Object Versioning of OpenStack Object Storage API.
+ This allows clients to put the ``X-Versions-Location`` attribute
+ on containers that should be versioned. The attribute specifies
+ the name of container storing archived versions. It must be owned
+ by the same user that the versioned container due to access
+ control verification - ACLs are NOT taken into consideration.
+ Those containers cannot be versioned by the S3 object versioning
+ mechanism.
+
+ The ``X-History-Location`` attribute, also understood by
+ OpenStack Swift for handling ``DELETE`` operations
+ `slightly differently
+ <https://docs.openstack.org/swift/latest/overview_object_versioning.html>`_
+ from ``X-Versions-Location``, is currently not
+ supported.
+:Type: Boolean
+:Default: ``false``
+
+
+``rgw trust forwarded https``
+
+:Description: When a proxy in front of radosgw is used for ssl termination, radosgw
+ does not know whether incoming http connections are secure. Enable
+ this option to trust the ``Forwarded`` and ``X-Forwarded-Proto`` headers
+ sent by the proxy when determining whether the connection is secure.
+ This is required for some features, such as server side encryption.
+:Type: Boolean
+:Default: ``false``
