Thor Script for Managing a Unicorn-driven App
Today I deployed a mini sinatra app on one of our test servers to manage some internal QA. I’ve put out quite a few apps backed by Unicorn in QA recently and finally wrote a little script to handle stopping, starting, and reloading of the unicorn processes. Nothing super special here, just thought I’d share a useful script. Drop the following code into your application’s
tasks directory, or place it on the app root and call it
tasks/unicorn.thor (or Thorfile)
From your application root directory, run any of the three commands. Keep in mind you’ll need a unicorn config file that actually dictates how Unicorn should behave (like number of workers, where your logs go, etc). You’ll also need a Rackup file (
config.ru ) which tells unicorn how to run your app.
Plop this puppy behind nginx and you’re golden. Thor has a lot more things you could do with this (like overriding which config file to use) by providing method-level options, but this is a great starting point for most people. Leave a comment if you have any improvements or other ways you handle this.
