How should secret files be pushed to an EC2 (on AWS) Ruby on Rails application?

How should secret files be pushed to an EC2 Ruby on Rails application using amazon web services with their elastic beanstalk?
I add the files to a git repository, and I push to github, but I want to keep my secret files out of the git repository. I'm deploying to aws using:
git aws.push
The following files are in the .gitignore:
/config/database.yml
/config/initializers/omniauth.rb
/config/initializers/secret_token.rb
Following this link I attempted to add an S3 file to my deployment:
http://docs.amazonwebservices.com/elasticbeanstalk/latest/dg/customize-containers.html
Quoting from that link:
Example Snippet
The following example downloads a zip file from an Amazon S3 bucket and unpacks it into /etc/myapp:
sources:
/etc/myapp: http://s3.amazonaws.com/mybucket/myobject
Following those directions I uploaded a file to an S3 bucket and added the following to a private.config file in the .elasticbeanstalk .ebextensions directory:
sources:
/var/app/current/: https://s3.amazonaws.com/mybucket/config.tar.gz
That config.tar.gz file will extract to:
/config/database.yml
/config/initializers/omniauth.rb
/config/initializers/secret_token.rb
However, when the application is deployed the config.tar.gz file on the S3 host is never copied or extracted. I still receive errors that the database.yml couldn't be located and the EC2 log has no record of the config file, here is the error message:
Error message:
No such file or directory - /var/app/current/config/database.yml
Exception class:
Errno::ENOENT
Application root:
/var/app/current
