We recently received an email from Heroku telling us that we would need to transition our deployments away from the ssh transport that we’ve been using on Semaphore CI to deploy our Elixir Phoenix app. The Semaphore deployment documentation only covers the ssh transport route. We needed to figure out how to move to the https deployments from our CI server. The instructions in the email were’t too helpful as those steps had already been taken in our project, the Semaphore solution replaces https with ssh for deployments.
