This document is for a development version of Ceph.

HTTP Frontends

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

New in version 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

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
