Setting Up Private GitHub Repos with Bundler on Heroku

To get a private GitHub repo to work on Heroku, you can leverage the netrc buildpack in conjunction with the Heroku Ruby buildpack.

When setting up the Gemfile, make sure to use the https GitHub URL. This mechanism does not work with git+ssh.

gem "some_private_gem", git: "https://github.com/org/some_private_gem.git"
