This document describes how to use the Ruby 2.0 feature on Engine Yard Cloud.

Get started with Ruby 2.0 on Engine Yard Cloud


  • This article assumes you already have an Engine Yard account. If not, see Sign up for an Engine Yard Account.
  • To use Ruby 2.0 in your environment, you must use the Engine Yard Gentoo 12.11 stack option (stable-v4).
  • Your environment must include other component versions as described in the Engine Yard Gentoo 12.11 Tech Stack.
  • You must:

    • Create a new environment. You cannot update an existing app environment at this time.
    • Use 64-bit instances (32-bit instances are not supported on this distribution).
  • In order to deploy your app, you must use the engineyard gem (2.1.0.rc1 or newer) with this feature.

    The engineyard gem can be installed by running:

    gem install engineyard

    See Deploying with engineyard gem version 2.0.

    Note: If you aren't sure which version of the engineyard gem you have installed, you can check with:

    $ ey --version
    engineyard version 2.1.0.rc1

Hi Vincent, please confirm: are you talking about upgrading from the Engine Yard Gentoo (stable-v2) to the Engine Yard Gentoo 12.11 (stable-v4) stack? Or are you referring to a different migration? thanks, kjm
