Configuration Options¶

periodic_task¶

These options apply to services using the periodic task features of oslo.service.

run_external_periodic_tasks¶

Type:	boolean
Default:	true

Some periodic tasks can be run in a separate process. Should we run them here?

service¶

These options apply to services using the basic service framework.

backdoor_port¶

Type:	string
Default:	<None>

Enable eventlet backdoor. Acceptable values are 0, <port>, and <start>:<end>, where 0 results in listening on a random tcp port number; <port> results in listening on the specified port number (and not enabling backdoor if that port is in use); and <start>:<end> results in listening on the smallest unused port number within the specified range of port numbers. The chosen port is displayed in the service’s log file.

backdoor_socket¶

Type:	string
Default:	<None>

Enable eventlet backdoor, using the provided path as a unix socket that can receive connections. This option is mutually exclusive with ‘backdoor_port’ in that only one should be provided. If both are provided then the existence of this option overrides the usage of that option.

log_options¶

Type:	boolean
Default:	true

Enables or disables logging values of all registered options when starting a service (at DEBUG level).

graceful_shutdown_timeout¶

Type:	integer
Default:	60

Specify a timeout after which a gracefully shutdown server will exit. Zero value means endless wait.

sslutils¶

These options apply to services using the SSL utilities module.

ca_file¶

Type:	string
Default:	<None>

CA certificate file to use to verify connecting clients.

Deprecated Variations¶

Group	Name
DEFAULT	ssl_ca_file

cert_file¶

Type:	string
Default:	<None>

Certificate file to use when starting the server securely.

Deprecated Variations¶

Group	Name
DEFAULT	ssl_cert_file

key_file¶

Type:	string
Default:	<None>

Private key file to use when starting the server securely.

Deprecated Variations¶

Group	Name
DEFAULT	ssl_key_file

version¶

Type:	string
Default:	<None>

SSL version to use (valid only if SSL enabled). Valid values are TLSv1 and SSLv23. SSLv2, SSLv3, TLSv1_1, and TLSv1_2 may be available on some distributions.

ciphers¶

Type:	string
Default:	<None>

Sets the list of available ciphers. value should be a string in the OpenSSL cipher list format.

wsgi¶

These options apply to services using the WSGI (Web Service Gateway Interface) module.

api_paste_config¶

Type:	string
Default:	api-paste.ini

File name for the paste.deploy config for api service

wsgi_log_format¶

Type:	string
Default:	%(client_ip)s "%(request_line)s" status: %(status_code)s  len: %(body_length)s time: %(wall_seconds).7f

A python format string that is used as the template to generate log lines. The following values can beformatted into it: client_ip, date_time, request_line, status_code, body_length, wall_seconds.

tcp_keepidle¶

Type:	integer
Default:	600

Sets the value of TCP_KEEPIDLE in seconds for each server socket. Not supported on OS X.

wsgi_default_pool_size¶

Type:	integer
Default:	100

Size of the pool of greenthreads used by wsgi

max_header_line¶

Type:	integer
Default:	16384

Maximum line size of message headers to be accepted. max_header_line may need to be increased when using large tokens (typically those generated when keystone is configured to use PKI tokens with big service catalogs).

wsgi_keep_alive¶

Type:	boolean
Default:	true

If False, closes the client socket connection explicitly.

client_socket_timeout¶

Type:	integer
Default:	900

Timeout for client connections’ socket operations. If an incoming connection is idle for this number of seconds it will be closed. A value of ‘0’ means wait forever.
