Rails 5.2 with master.key - Heroku deployment

Rails 5.2 introduces the encrypted secrets feature through the usage of the awesome credentials.yml. But I'm struggling to get it to work with Heroku.

Is there any Strategy available right now to deploy a Rails 5.2 App to Heroku?

You could also use the following command to create Heroku RAILS_MASTER_KEY with the contents of your local config/master.key:

heroku config:set RAILS_MASTER_KEY="$(< config/master.key)"

Note: make sure you are in the directory that contains your Rails app.

You should set the environment variable RAILS_MASTER_KEY, either on your heroku web dashboard, or using console:

$ heroku config:set RAILS_MASTER_KEY=<your-master-key>

Example:

$ heroku config:set RAILS_MASTER_KEY=123456789

(The < and > are placeholders)

Rails will detect this variable and use it as your master key (instead of looking for it in master.key file).
