Add an ssh key to your build.
Adapted from SectorLabs/heroku-buildpack-git-submodule.
-
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. -
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
.
