Moonshine works with rails to get your gem dependency. In addition, it handles installing native dependencies (ie nokogiri requires libxml).
Not using bundler
Adding a new gem to a Rails application managed by Moonshine is a three step process.
1. Add gem to environment.rb
... config.gem "my_cool_gem" ...
2. Update your config/gems.yml
This will regenerate your config/gems.yml to reflect the gems in your environment.rb. Be sure to add this to your git repo by doing:
git add config/gems.yml && git commit -m "Added config/gems.yml generated by moonshine"
3. Deploy your application
The next time you deploy your application Moonshine will ensure all gems specified in config/gems.yml are installed on your server.
If you have a
Gemfile in your app, then
bundle install is run for you automatically during deploy. It will also take care of system dependencies of these gems.
Currently, the bundler support will not install system dependencies, pending a rubygems 1.3.6 release. In the interim, you will need to manually specify these in your
application_manifest.rb. For nokogiri, for example, you’d need this:
def application_packages package 'libxml2-dev', :before => exec('bundle install') package 'libxslt1-dev', :before => exec('bundle install') end recipe :application_packages
Moonshine maintains a mapping of gems to native packages. You can find this in
If you to define extra mappings, you can update this locally in your
:apt_gems: :awesomegem: - awesome - libawesome-dev
If moonshine is missing mappings for publicly available gems, please open an issue
