OpenSolaris Ruby On Rails 2 AMI provided by Sun Microsystems, Inc.

This image, based on Sun's OpenSolaris 32-bit image , ami-41e70328, is a complete and optimized Ruby On Rails stack with DTrace support built into it. This stack includes, Mongrel, Mongrel_cluser, Thin, MySQL, Postgres, sample SMF scripts, the Blastwave client, Git, Ruby clients for the databases/S3, GNU Findutils, gcc, and Sun Studio. This AMI is provided by Sun Microsystems and requires registration.

Description:

We provide a documented sample SMF manifest to aid Rails deployers, available at /root/rails-sample.smf along with a basic Rails application that can be managed with it as an example. The PATH environment variable for the root user includes the software directories. Ruby is available in /usr/ruby/1.8/bin(and symbolically linked from /usr/bin), and the gem home(often set by GEM_HOME) is /var/ruby/1.8/gem_home. This is documented in the Ruby OpenSolaris ARC case.

DTrace probes have been integrated into the Ruby source code, and this provide low overhead monitoring for your Rails application.

The base AMI used was the Sun OpenSolaris 2008.05, with updated software revisions to build91. The OpenSolaris distribution is based on the OpenSolaris project, and features functionality such as ZFS, DTrace, and a new packaging system, the Image Packaging System(IPS). IPS is a network based package management system that allows for users to install applications from online repositories using the "pkg" command. Developers can install additional software on this AMI from repository using the pkg command. The root filesystem is ZFS in this AMI.

Also included in the AMI is the OpenSolaris client for Blastwave.org, pkg-get(it's available in root's PATH).
