I would like to set some setting parameter (such as S3 parameter) by using env variable instead of GUI, is it possible and where I can find the name of the ENV for this ?

Piece of cake.

Simply take any of the settings that you can see, capitalise it to keep things consistent, add `DISCOURSE` to it, and link it all up with `_`'s (underscores).

You then put this in app.yml before the `volumes:` section, indenting it exactly (usually with 2 spaces) as the other environmental settings in there.

For example:

```plaintext
  DISCOURSE_BACKUP_LOCATION: 's3'

```

Hey there. Does this work for any Site setting configuration? For example for [Discourse Connect](https://meta.discourse.org/t/13045?silent=true) does that work?

It should, since [DiscourseConnect](https://meta.discourse.org/t/13045?silent=true) is a core feature (then again, I think plugins’ settings can also be set).
