Rails + GIT Gems

1_README.md

In order to deal with GIT based gems, you'll need to make add some additional .ebextensions/*.config files.

1. Support GIT in your EC2 instance;
2. Backup the existing bundle command
3. Bootstrap your rails project to add in your vendor directory to the shared environment
4. Replace your bundle_install with a better bundle_install_deployment approach

Please note that these are placed in your Rails applications .ebextensions folder.
