Possible to not log user IP addresses?

Here begins my problem: how do i implement this for Discourse?

That solution requires the commercial version of nginx, not the open source one. The simple solution to use that without interfering with the Docker install is to get that version of nginx as a proxy for your Discourse and to use the IP address rewriter to create the X-Forwarded-For header.
