Environment Variables

For settings that can be managed with Instance Settings, you can either set the values via environment variables or through the Instance Settings page in your instance. However, it is strongly recommended to use Instance settings. Environment variables are only loaded when there are no values in Instance settings, which means that environment variables could reflect outdated values.

For other settings, there are various environment variables you can set to configure your instance. Below is a comprehensive list of all of them.
