== RedUnicorn
RedUnicorn provides easy interaction with unicorn processes. It uses signals to communicate with unicorn to check its status, stop the processes or to provide zero downtime restarts.
=== Usage
$ red_unicorn --help RedUnicorn::Unicorn: Unicorn process interactions Usage: red_unicorn [opts] (prolicide | status | slaughter | start | restart | reload | stop | birth) -h, --help Show this help screen -p, --pid-file /path/to/file.pid Specify path to PID file (default: /var/run/unicorn/unicorn.pid) -x, --unicorn-exec /path/to/unicorn Specify path to unicorn executable (default: /var/www/shared/bundle/bin/unicorn_rails) -c, --unicorn-config /path/to/config Specify path to unicorn configuration file (default: /etc/unicorn/app.rb) -t, --timeout 30 Specify timeout for running actions -g, --restart-grace 8 Specify grace time to start replacement children (default: 8 seconds) -e, --env production Specify environment (default: production) -k, --kind (unicorn|gunicorn) Specify kind of unicorn in use (default: unicorn) Commands: prolicide: Kill single worker process status: Returns current unicorn status slaughter: Kill all worker processes (master remains) start: Start unicorn restart: Gracefully restart unicorn (zero downtime) reload: Reload unicorn configuration stop: Stop unicorn birth: Create new worker process
=== Zero downtime restarts
RedUnicorn does its best to provide true zero downtime restarts. After sending unicorn the restart signal, it will wait until the new unicorn process has forked out workers before killing the original unicorn process. If no worker processes are started, the old unicorn process will be left running.
=== Unicorn agnostic
RedUnicorn is compatible with unicorn and gunicorn.
