NextCloud: Heroku: Install: Create Heroku Environment Variables
From Gratiel's Wiki
Environment Variables
Instead of storing security credentials within the config file, we are going to store them as environment variables. This keeps the security credentials out of the git repository.
Heroku Settings
To get to Heroku's Environment Variables, we need to get to the Settings Tab Section. In your dashboard, go to the infinite-lowlands-88888 app. You will be in the Overview tab section.
Select the Settings Tab Section
Click on the Reveal Config Vars button to view the Environment Variables associated to your app.
Add all the Environment Variables (Config Vars) shown below, and be sure to add the associated values that correspond to your app.
