Help creating a foreman plugin

Support
1

This may seem like a simple thing to the ruby gurus but as a complete newb
to ruby I cant figure it out.

All I need to do is create a very simple foreman plugin to add a static
html link to the foreman menu. I've been looking at the 'How to create a
plugin' wiki
(How to Create a Plugin - Foreman).

I have cloned the git repo to '/opt/mldsrepolink', run the rename script
and created the below file:

cat /usr/share/foreman/bundler.d/Gemfile.local.rb
gem 'mldsrepolink', :path => '/opt/mldsrepolink'

After restarting httpd I can no longer access foreman:

Gem loading error: cannot load such file – mldsrepolink (RuntimeError)

Is the info on the wiki page still valid? Im running foreman 1.5 on Redhat 6

All help appreciated.

It's valid, but only on a development installation using Bundler. The
RPM installs use a tool called bundler_ext for production-style installs
using RPMs rather than rubygems.

You'll either need to set up a development environment (i.e.
Foreman :: Contribute) or generate a .gem file (gem
build *.gemspec) and install this on your EL system with "scl enable
ruby193 gem install …/foo-1.0.gem" which you can use then from the
Gemfile.local.rb without the :path option.

Cheers,
