supervisor-stdout | simple supervisord event listener to relay | Continuous Deployment library

I have a Dockerized Django application, which I'm orchestrating with Supervisor, which is not optimal but needed when hosting on Azure app services as their multi-app support with docker-compose is still in preview mode (aka. beta).

According to best-practises I have configured each application within supervisord to emit the logs to STDOUT. It works fine when I create the Docker image locally, run it and check the docker logs. However, when I have deployed it to Azure app services and check the logs, my web-application (Gunicorn) is logging as expected, however, the logs from NGINX don't appear at all.

I have tried different configurations in my Dockerfile for linking the log files generated by NGINX (linking to both /dev/stdout and /dev/fd/1 for example) and I have also gone into the the nginx.conf config and trying to log out directly to /dev/stdout. But whatever I do it work fine locally, but on Azure the logs don't show any NGINX-logs. I've pasted relevant configuration files, where you can see the commented lines with the options I've tried with. Hope someone can help me figure this one out.

EDIT: I've also tried logging the NGINX app to a log-file in the system, which also works fine locally, but not in Azure app-services. I tried deactivating the "user nginx" part in nginx.conf as I though it could have something to do with permissions, but that didn't help either.

EDIT 2: I also tried creating the log files in my home-directory in the web-app at Azure, thinking it may had to do with not being able to create logs in other directories - again, it works locally, but the logs in Azure are empty.
