A group of Unicorns is called a blessing.
Blessing is a script to manage multiple Unicorn Rack servers.
gem install blessing
Blessing CLI script takes at least one argument, which provides a list of Unicorn configuration files and then starts Unicorn instances from them.
blessing /var/www/rails_app/config/unicorn.conf blessing /var/www/*/config/unicorn.conf blessing /var/vhosts/**/config/unicorn.conf
After starting the servers, Blessing keeps monitoring the given list of configurations and reacts to the following events:
when a conf file is changed, restarts the corresponding Unicorn instance
when a new conf is found (via globbing), starts a new instance
when a conf is removed, stops the corresponding instance
Blessing reacts to the following signals:
INT, TERM - shut down Blessing group gracefully
USR1 - immediately rerun verification cycle
USR2 - try to resurrect dead Unicorns
Contributing to blessing
Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it
Fork the project
Start a feature/bugfix branch
Commit and push until you are happy with your contribution
Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
