Generally - it's good to pay attention to benchmarks and speed requirements, but I wouldn't worry too much about it unless you know the app server is your bottleneck (premature optimisation and all that). The Gunicorn access log is very similar to the NGINX access log, it records all the requests coming in to the Gunicorn server: Instead, you run the Burp-UI create_app method directly. See the Gunicorn documentation for more information.. Next, check your nginx.conf file to ensure that the relevant location block specifies the same socket information Gunicorn is using.

The best way to configure a Docker Container is using environment variables, Gunicorn does not natively support this. Adding a configuration file # An IP is a valid HOST. If empty the logs would be handle by upstart.
