Custom SSH keys buildpack

This buildpack allows you to set multiple ssh keys per repository.

It is useful e.g. for GitHub deploy keys, which have to be unique per repository.

You have to set a comment for each private key with a repository name - repo_owner/repo_name.git.

You can change an existing key comment with this command:

ssh-keygen -c -C "repo_owner/repo_name.git" -f /path/to/private/key

Installation

Put your private keys as Heroku environment variables with variable name in the following format:

GITHUB_DEPLOY_KEY_#

where # is index of a given key (e.g. 0, 1, 2...):

heroku config:set GITHUB_DEPLOY_KEY_0="-----BEGIN RSA PRIVATE KEY-----...."
heroku config:set GITHUB_DEPLOY_KEY_1="-----BEGIN RSA PRIVATE KEY-----...."
...

Then add the buildpack to your Heroku app. It should be set as the first (default) one:

heroku buildpacks:add https://github.com/baronapp/represent-custom-ssh-keys-buildpack.git -i 1
