Zero downtime deploys with unicorn + nginx + runit + rvm + chef

Below are the actual files we use in one of our latest production applications at Agora Games to achieve zero downtime deploys with unicorn. You've probably already read the GitHub blog post on Unicorn and would like to try zero downtime deploys for your application. I hope these files and notes help. I am happy to update these files or these notes if there are comments/questions. YMMV (of course).

Other application notes:

• Our application uses MongoDB, so we don't have database migrations to worry about as with MySQL or postgresql. That does not mean that we won't have to worry about issues with the database with indexes being built in MongoDB or what have you.
• We use capistrano for deployment.

Salient points for each file:

• This creates a 560mb ramdisk. Adjust the size accordingly. I think the number at the end of the command is the number of disk blocks. They are 2kb in size for me.
• Restarting postgres is not necessary; you can create the ramdisk and tablespace while postgres is running.
• You will lose all data in the ramdisk tablespace when you shut your machine down
