mongrel unicorn - Feb 2012 - Deployment with Capistrano and Foreman

Hi guys,

I wonder how do you deploy Unicorn Rails apps using Foreman and the upstart.

The things I''m not sure how to deal with are:

- restarting the Unicorn with no downtime. With upstart I think the master
process gets restarted.
- running app as unprivileged user (not sure how to use Forman with upstat at
all here).

A lot of things are really related to Foreman (the ruby one), but it would help
to hear some of the ways you guys do it.


Cheers,

I''ll defer to actual Foreman/upstart users for this.  Any solution that
works with nginx (while keeping the master process in use) should work
with unicorn, too.  I designed unicorn so it could be managed nearly
identically to nginx.

You can use the "user" directive in the unicorn config file, this
only affects the worker processes, though.

You can always use su or sudo to ensure the master process is
unprivileged, too.
