Most of the services can be run in the foreground you will have to look at the help for each to determine the correct options for calling the configuration files, but an example would be:
- keystone-all
- neutron-server
- nova-api
These are just a few but it should give you a head start.
# glance-api --help
usage: glance-api [-h] [--config-dir DIR] [--config-file PATH] [--debug]
[--log-config-append PATH] [--log-date-format DATE_FORMAT]
[--log-dir LOG_DIR] [--log-file PATH] [--log-format FORMAT]
[--nodebug] [--nouse-syslog] [--nouse-syslog-rfc-format]
[--noverbose] [--syslog-log-facility SYSLOG_LOG_FACILITY]
[--use-syslog] [--use-syslog-rfc-format] [--verbose]
[--version]
optional arguments:
-h, --help show this help message and exit
--config-dir DIR Path to a config directory to pull *.conf files from.
This file set is sorted, so as to provide a
predictable parse order if individual options are
over-ridden. The set is parsed after the file(s)
specified via previous --config-file, arguments hence
over-ridden options in the directory take precedence.
--config-file PATH Path to a config file to use. Multiple config files
can be specified, with values in later files taking
precedence. The default files used are: None.
--debug, -d Print debugging output (set logging level to DEBUG
instead of default WARNING level).
--log-config-append PATH, --log_config PATH
The name of a logging configuration file. This file is
appended to any existing logging configuration files.
For details about logging configuration files, see the
Python logging module documentation.
--log-date-format DATE_FORMAT
Format string for %(asctime)s in log records. Default:
None .
--log-dir LOG_DIR, --logdir LOG_DIR
(Optional) The base directory used for relative --log-
file paths.
--log-file PATH, --logfile PATH
(Optional) Name of log file to output to. If no
default is set, logging will go to stdout.
--log-format FORMAT DEPRECATED. A logging.Formatter log message format
string which may use any of the available
logging.LogRecord attributes. This option is
deprecated. Please use logging_context_format_string
and logging_default_format_string instead.
--nodebug The inverse of --debug
--nouse-syslog The inverse of --use-syslog
--nouse-syslog-rfc-format
The inverse of --use-syslog-rfc-format
--noverbose The inverse of --verbose
--syslog-log-facility SYSLOG_LOG_FACILITY
Syslog facility to receive log lines.
--use-syslog Use syslog for logging. Existing syslog format is
DEPRECATED during I, and will change in J to honor
RFC5424.
--use-syslog-rfc-format
(Optional) Enables or disables syslog rfc5424 format
for logging. If enabled, prefixes the MSG part of the
syslog message with APP-NAME (RFC5424). The format
without the APP-NAME is deprecated in I, and will be
removed in J.
--verbose, -v Print more verbose output (set logging level to INFO
instead of default WARNING level).
--version show program's version number and exit
