Packaging ruby and puppet together to avoid using rvm

People at my place don’t trust rvm.

Personally found it easy to switch between different ruby versions to test things out.

Had to find a way to avoid using rvm and also not rely on the system wide ruby in the production machines.

Decided to build the newest ruby and install the puppet gem using the just installed ruby.

After ./configure ing with a –prefix flag to keep the install isolated,  I had to override the default PATH variable to point to the ruby we just built and installed.

export GEM_HOME=${PUPPET_RUBY_DIR}/lib/ruby/gems/1.9.1/gems/
export GEM_PATH=${PUPPET_RUBY_DIR}/lib/ruby/gems/1.9.1/gems/

Now Gem install the desired puppet and packaged the whole directory with fpm or your favorite rpmbuild tool.

(I’ll make this rpm available somewhere for anyone interested).

Installing this rpm gives me isolated ruby and puppet that doesn’t rely on the system ruby or the rvm.

My puppet client has this startup script,  setting all the ruby path and gem path

#set -x
# Usage
 echo "Usage: $0 master_server extra_opts " 
 echo "Extra_opts --waitforcert 20 -v -d --environment staging --trace --logdest /var/log/puppet/puppetd.log " 
 exit 1
[[ $1 == "-h" ]] && usage 
[[ $1 == "-help" ]] && usage
# Need params
[[ $# -lt 1 ]] && usage


# Let the path find puppet's ruby first 
# Set the GEM home and path for the puppet ruby
export GEM_HOME=${PUPPET_RUBY_DIR}/lib/ruby/gems/1.9.1/gems/
export GEM_PATH=${PUPPET_RUBY_DIR}/lib/ruby/gems/1.9.1/gems/



Have not encountered any obvious failing with this approach,  now to test these in a completely fresh system to make sure I’m not missing anything.

Couldn’t shake off the feeling that I’m missing something though.
