I'd like to set up Discourse, so all public images get uploaded directly to an S3 bucket. According to Discourse documentation, I need to do that using a GUI.
However, I am running the application inside the container (Kubernetes) and would like to have S3 uploads enabled and configured before launching the application.
So far, I found a file, called /bitnami/discourse/conf/discourse.conf, which has settings for DB, Redis.
What environment variables do I need to set up in order to have that config populated with S3 bucket settings ?
