============== HTTP Frontends

.. contents::

The Ceph Object Gateway supports two embedded HTTP frontend libraries that can be configured with rgw_frontends. See :ref:radosgw-config-ref 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 an IPv6 endpoint would listen to IPv6 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_reload

:Description: Optional interval in seconds to periodically recreate the SSL context, which reloads the SSL certificate and private key from their specified paths. A value of 0 disables this feature. The reload is non-disruptive to existing connections. If the reload fails, the previous context continues to be used.

:Type: Integer :Default: 0

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 Nagle's algorithm for all sockets.

          ``0`` Keep the default: Nagle'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

max_header_size

:Description: The maximum number of header bytes available for a single request.

:Type: Integer :Default: 16384 :Maximum: 65536

so_reuseport

:Description: If set allows multiple RGW instances on a host to listen on the same TCP port.

          ``1`` Enable running multiple RGW on same port.

          ``0`` Disallow running multiple RGW on same port.

:Type: Integer (0 or 1) :Default: 0

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
