Heroku Buildpack: Custom SSH key

Use Custom SSH key buildpack if you need to, for example, download a dependency stored in a private repository.

Based on http://stackoverflow.com/a/29677091/3303182.

Usage

• Add the buildpack to your app: Heroku buildpacks:add --index 1 https://github.com/abtion/custom-ssh-key-buildpack --app fguplaner-backend-ci

• Generate a new SSH key (https://help.github.com/articles/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent/)

  For this example I will suppose that you named the key deploy_key.

• Add the ssh key as a deploy key to the private repository

  • Github: https://developer.github.com/v3/guides/managing-deploy-keys/#deploy-keys

• Encode the private key as a base64 string and add it as the IPUNG_SSH_KEY environment variable of the Heroku app.

• Encode the private key as a base64 string and add it as the COSA_SSH_KEY environment variable of the Heroku app.

Add the deploy key to Heroku configuration

# OSX
$ Heroku config:set IPUNG_SSH_KEY=$(base64 --input nordplaner_ipung_deploy_key.rsa) --app fguplaner-backend-ci
$ Heroku config:set COSA_SSH_KEY=$(base64 --input nordplaner_cosa_deploy_key.rsa) --app fguplaner-backend-ci

• Deploy your app and enjoy :)
