rainbows - rackup-like command to launch Rainbows!
rainbows [-c CONFIG_FILE] [-E RACK_ENV] [-D] [RACKUP_FILE]
A rackup(1)-like command to launch Rack applications using Rainbows!. It is expected to be started in your application root (APP_ROOT), but the "working_directory" directive may be used in the CONFIG_FILE. While Rainbows! takes a myriad of command-line options for compatibility with ruby(1) and rackup(1), it is recommended to stick to the few command-line options specified in the SYNOPSIS and use the CONFIG_FILE as much as possible.
This defaults to "config.ru" in APP_ROOT. It should be the same file used by rackup(1) and other Rack launchers, it uses the Rack::Builder DSL. Embedded command-line options are mostly parsed for compatibility with rackup(1) but strongly discouraged.
-c, --config-file CONFIG_FILE Path to the Unicorn-specific config file. The config file is implemented as a Ruby DSL, so Ruby code may executed. See the RDoc/ri for the Unicorn::Configurator class for the full list of directives available from the DSL. -D, --daemonize Run daemonized in the background. The process is detached from the controlling terminal and stdin is redirected to "/dev/null". Unlike many common UNIX daemons, we do not chdir to "/" upon daemonization to allow more control over the startup/upgrade process. Unless specified in the CONFIG_FILE, stderr and stdout will also be redirected to "/dev/null". -E, --env RACK_ENV Run under the given RACK_ENV. See the RACK ENVIRONMENT section for more details. -l, --listen ADDRESS Listens on a given ADDRESS. ADDRESS may be in the form of HOST:PORT or PATH, HOST:PORT is taken to mean a TCP socket and PATH is meant to be a path to a UNIX domain socket. Defaults to "0.0.0.0:8080" (all addresses on TCP port 8080) For production deployments, specifying the "listen" directive in CONFIG_FILE is recommended as it allows fine-tuning of socket options. -N, --no-default-middleware Disables loading middleware implied by RACK_ENV. This bypasses the configuration documented in the RACK ENVIRONMENT section, but still allows RACK_ENV to be used for application/framework-specific purposes.
RACKUP COMPATIBILITY OPTIONS
-o, --host HOST Listen on a TCP socket belonging to HOST, default is "0.0.0.0" (all addresses). If specified multiple times on the command-line, only the last-specified value takes effect. This option only exists for compatibility with the rackup(1) command, use of "-l"/"--listen" switch is recommended instead. -p, --port PORT Listen on the specified TCP PORT, default is 8080. If specified multiple times on the command-line, only the last-specified value takes effect. This option only exists for compatibility with the rackup(1) command, use of "-l"/"--listen" switch is recommended instead. -s, --server SERVER No-op, this exists only for compatibility with rackup(1).
-e, --eval LINE Evaluate a LINE of Ruby code. This evaluation happens immediately as the command- line is being parsed. -d, --debug Turn on debug mode, the $DEBUG variable is set to true. -w, --warn Turn on verbose warnings, the $VERBOSE variable is set to true. -I, --include PATH specify $LOAD_PATH. PATH will be prepended to $LOAD_PATH. The ':' character may be used to delimit multiple directories. This directive may be used more than once. Modifications to $LOAD_PATH take place immediately and in the order they were specified on the command-line. -r, --require LIBRARY require a specified LIBRARY before executing the application. The "require" statement will be executed immediately and in the order they were specified on the command-line.
The following UNIX signals may be sent to the master process: · HUP - reload config file, app, and gracefully restart all workers · INT/TERM - quick shutdown, kills all workers immediately · QUIT - graceful shutdown, waits for workers to finish their current request before finishing. · USR1 - reopen all logs owned by the master and all workers See Unicorn::Util.reopen_logs for what is considered a log. · USR2 - reexecute the running binary. A separate QUIT should be sent to the original process once the child is verified to be up and running. · WINCH - gracefully stops workers but keep the master running. This will only work for daemonized processes. · TTIN - increment the number of worker processes by one · TTOU - decrement the number of worker processes by one See the SIGNALS (http://rainbows.bogomips.org/SIGNALS.html) document for full description of all signals used by Rainbows!.
Accepted values of RACK_ENV and the middleware they automatically load (outside of RACKUP_FILE) are exactly as those in rackup(1): · development - loads Rack::CommonLogger, Rack::ShowExceptions, and Rack::Lint middleware · deployment - loads Rack::CommonLogger middleware · none - loads no middleware at all, relying entirely on RACKUP_FILE All unrecognized values for RACK_ENV are assumed to be "none". Production deployments are strongly encouraged to use "deployment" or "none" for maximum performance. Note the Rack::ContentLength and Rack::Chunked middlewares are also loaded by "deployment" and "development", but no other values of RACK_ENV. If needed, they must be individually specified in the RACKUP_FILE, some frameworks do not require them.
