HTTP Frontends
==============
.. contents::
The Ceph Object Gateway supports two embedded HTTP frontend libraries
that can be configured with ``rgw_frontends``. See `Config Reference`_
for details about the syntax.
Beast
=====
.. versionadded:: Mimic
The ``beast`` frontend uses the Boost.Beast library for HTTP parsing
and the Boost.Asio library for asynchronous network i/o.
Options
-------
``port`` and ``ssl_port``
:Description: Sets the ipv4 & ipv6 listening port number. Can be specified multiple
times as in ``port=80 port=8000``.
:Type: Integer
:Default: ``80``
``endpoint`` and ``ssl_endpoint``
:Description: Sets the listening address in the form ``address[:port]``, where
the address is an IPv4 address string in dotted decimal form, or
an IPv6 address in hexadecimal notation surrounded by square
brackets. Specifying a IPv6 endpoint would listen to v6 only. The
optional port defaults to 80 for ``endpoint`` and 443 for
``ssl_endpoint``. Can be specified multiple times as in
``endpoint=[::1] endpoint=192.168.0.100:8000``.
:Type: Integer
:Default: None
``ssl_certificate``
:Description: Path to the SSL certificate file used for SSL-enabled endpoints.
If path is prefixed with ``config://``, the certificate will be
pulled from the ceph monitor ``config-key`` database.
:Type: String
:Default: None
``ssl_private_key``
:Description: Optional path to the private key file used for SSL-enabled
endpoints. If one is not given, the ``ssl_certificate`` file
is used as the private key.
If path is prefixed with ``config://``, the certificate will be
pulled from the ceph monitor ``config-key`` database.
:Type: String
:Default: None
``ssl_options``
:Description: Optional colon separated list of ssl context options:
``default_workarounds`` Implement various bug workarounds.
``no_compression`` Disable compression.
``no_sslv2`` Disable SSL v2.
``no_sslv3`` Disable SSL v3.
``no_tlsv1`` Disable TLS v1.
``no_tlsv1_1`` Disable TLS v1.1.
``no_tlsv1_2`` Disable TLS v1.2.
``single_dh_use`` Always create a new key when using tmp_dh parameters.
:Type: String
:Default: ``no_sslv2:no_sslv3:no_tlsv1:no_tlsv1_1``
``ssl_ciphers``
:Description: Optional list of one or more cipher strings separated by colons.
The format of the string is described in openssl's ciphers(1)
manual.
:Type: String
:Default: None
``tcp_nodelay``
:Description: If set the socket option will disable Nagle's algorithm on
the connection which means that packets will be sent as soon
as possible instead of waiting for a full buffer or timeout to occur.
``1`` Disable Nagel's algorithm for all sockets.
``0`` Keep the default: Nagel's algorithm enabled.
:Type: Integer (0 or 1)
:Default: 0
``max_connection_backlog``
:Description: Optional value to define the maximum size for the queue of
connections waiting to be accepted. If not configured, the value
from ``boost::asio::socket_base::max_connections`` will be used.
:Type: Integer
:Default: None
``request_timeout_ms``
:Description: The amount of time in milliseconds that Beast will wait
for more incoming data or outgoing data before giving up.
Setting this value to 0 will disable timeout.
:Type: Integer
:Default: ``65000``
``rgw_thread_pool_size``
:Description: Sets the number of threads spawned by Beast to handle
incoming HTTP connections. This effectively limits the number
of concurrent connections that the frontend can service.
:Type: Integer
:Default: ``512``
``max_header_size``
:Description: The maximum number of header bytes available for a single request.
:Type: Integer
:Default: ``16384``
:Maximum: ``65536``
Generic Options
===============
Some frontend options are generic and supported by all frontends:
``prefix``
:Description: A prefix string that is inserted into the URI of all
requests. For example, a swift-only frontend could supply
a uri prefix of ``/swift``.
:Type: String
:Default: None
