heroku-buildpack-ssh-key

Add an ssh key to your build.

Adapted from SectorLabs/heroku-buildpack-git-submodule.

1. Add the buildpack to your Heroku app:

   $ heroku buildpacks:add https://github.com/heroku/heroku-buildpack-ssh-key.git -i 1
   

   Keep in mind that the buildpack order is important. If you'll specify this buildpack after your default one (e.g. heroku/nodejs) it'll not work. See https://devcenter.heroku.com/articles/using-multiple-buildpacks-for-an-app for details.

2. Set BUILDPACK_SSH_KEY to the private SSH key you want added:

   $ heroku config:set BUILDPACK_SSH_KEY="$(cat ~/.ssh/id_rsa)"
   

The buildpack will save the SSH key to your build at ~/.ssh/id_rsa.
