[chef] Re: application_ruby ruby/rails version

[Gavin Reynolds < >]

Hi Rob,

It’s not that you need to tell application_ruby where your locally built Ruby 
is, it’s more that you need to tell bundler where it is. It’s not entirely 
obvious, but the best way I’ve found is to use a wrapper for bundler which 
puts your version of Ruby in the path first.

I’d asked a while back in #chef IRC and was pointed towards: 
https://gist.github.com/grahamc/0c4079e43b5f997a5bd6

Essentially, you create a wrapper that is dropped at the root of your 
deployment path. The wrapper overrides the path so your local Ruby is first 
and passes any arguments through to the bundle command. In your application 
LWRP call, set the bundle_command to the wrapper. As a result, any commands 
executed by application_ruby as part of deploying your Rails app that call 
bundler are now run with your locally built Ruby. 

Also, after you've built your local Ruby with ruby_build_ruby, make sure to 
install the bundler, rake and builder gems into that local Ruby as well, 
otherwise it won’t work :).

As for setting a specific Rails version, the best/only sensible way to do 
that is through specifying a version for the Rails gem in your Gemfile for 
Bundler.

Hope that helps!

Regards,
Gavin
