[MM3-users] How to set uWSGI buffer size in mailman3 with Dcoker

Running into an issue where users are getting a 502 bade gateway and we traced it down to the headers that are getting sent when they request web pages. This looks like our issue

By default, uWSGI allocates a very small buffer (4096 bytes) for the headers of each request. If you start receiving “invalid request block size” in your logs, it could mean you need a bigger buffer. Increase it (up to 65535) with the buffer-size option.

So any idea on how to set this in mailman3 running in the maxking docker environment?
