Discourse: If S3 is enabled, is it recommended to configure in the yml or the admin panel?

Hi, for Discourse, if enabling S3, is it recommended to configure it in the YML file or via the admin UI (/admin/site_settings/category/files)?

We recommend the YML file if you’re self-hosting, Configure an S3 compatible object storage provider for uploads

@Discourse

Configuring these settings in environment variables in your app.yml is recommended because it’s how CDCK does it in their infrastructure, so it’s well-tested. Also, the task to upload assets happen after assets are compiled, which happens in a rebuild. If you want to spin a Discourse that works properly with Object Storage since the beginning you need to set the env vars so the assets are uploaded before the site starts.

If you’re using discourse.org hosting we handle upload storage, so you don’t have access to these settings.
