Installing a Gem on Heroku from a Private GitHub Repo

Sometimes you want to use a gem on Heroku that is in a private repository on GitHub.

Using git over http you can authenticate to GitHub using basic authentication. However, we don't want to embed usernames and passwords in Gemfiles. Instead, we can use authentication tokens.

1. Get an OAuth Token from GitHub

First you will need to get an OAuth Token from GitHub using your own username and "note"

So i was using Rails 4.1 with Unicorn v4.8.2 and when i tried to deploy my app it doesn't start properly and into the unicorn.log file i found this error message:

  "app error: Missing `secret_key_base` for 'production' environment, set this value in `config/secrets.yml` (RuntimeError)"

After a little research i found that Rails 4.1 change the way to manage the secret_key, so if we read the secrets.yml file located at exampleRailsProject/config/secrets.yml (you need to replace "exampleRailsProject" for your project name) you will find something like this:
  
  # Do not keep production secrets in the repository,
  # instead read values from the environment.
  production:
    secret_key_base: <%= ENV["SECRET_KEY_BASE"] %>

Sometimes you want to use a gem on Heroku that is in a private repository on GitHub.

Using git over http you can authenticate to GitHub using basic authentication. However, we don't want to embed usernames and passwords in Gemfiles. Instead, we can use authentication tokens.

This method does not add your OAuth token to Gemfile.lock. It uses bundle config to store your credentials, and allows you to configure Heroku to use environment variables when deploying.

1. Generate an OAuth token from GitHub
