zefer / heroku_cedar_hirefire_patch.rb
Created July 14, 2011 15:28
Patch HireFire so worker auto-scaling works on the Beta Heroku Cedar stack
# hopefully a temporary patch so HireFire will run on the Heroku Cedar stack
# NB: the worker type is hard-coded as "worker" below, this must correlate to the type in Procfile
# NB: ENV['APP_NAME'] must be defined (e.g. 'heroku config:add APP_NAME=myherokuappname')
# using ps & ps_scale instead of info & set_workers
