Using gem from new puppetserver custom function?

[Schofield]

I am testing out the new puppetserver and finding a problem with referencing a gem installed to the local ruby. 

A custom function is installed to /usr/lib/ruby/site_ruby/1.8/pupppet/parser/functions/myfunction.rb.  It makes use of the mysql2 gem

    module Puppet::Parser::Functions
      newfunction(:myfunction, :type => :rvalue) do |args|
        require 'mysql2'
        ...
    end

The mysql2 gem is installed to /usr/lib/ruby/gems/1.8/gems/mysql2-0.3.16/lib/mysql2.rb.

When doing a puppet run on a managed node we get the following error.

    Error: Could not retrieve catalog from remote server: Error 400 on SERVER: no such file to load -- mysql2

My question is: How make a gem visible to the new puppetserver so it can be used by a custom function?

I should note this set up works fine when running puppetmaster 3.7 instead of the new puppetserver.

Have you done the steps described here: https://github.com/puppetlabs/puppet-server/blob/master/documentation/gems.markdown

Best,

Thanks for the reply.  That does indeed look to be the solution.

Piggybacking off the same topic.

I have a few parsers that use the JSON gem so require 'json' is at the top of my parser which requires the native C extensions.  Does the new puppet server come with a jrbuy version of the json gem that contains the functions?  How would I write a parser that can be used on the ruby puppet master and the new jruby puppet server if the gems are slightly different and have different method names?

I just spent a little time looking into this, and the json gem appears to work just fine under JRuby.  It looks like there *used* to be a gem called json-jruby that could be used instead, but it appears that it has now been merged into json - so, long story short, 'json' should work just fine.
